Selecting New Tires and Wheels
Posted February 17, 2012 11:06 AM
Some of us just love tires. All those little rubber hairs on new tires and the smell is wonderful. We live in a great time for tires. No matter how you drive, where you want to go or the look you're after; there is a tire for you.
The same is true about wheels. The hardest part is choosing from the thousands of wheels available.
We may not be able to help with that, but we can help you get some things in mind before you consult with your Mountain View tire professional. Let's start with function and think about how you drive.
For example, maybe you have a large SUV but you don't drive off-road, so an off-road tread isn't important. Also, because you are not out bouncing over rocks in the California backcountry, you don't need a high profile tire to protect your rims. So that means you can probably go with the low-wide look.
If you have a winter season with rain and snow or if you find you need better ice and snow performance, they make great, high-performance snow tires that won't make it look like you are driving a tractor.
There really are a lot of options for any given vehicle. You will find it very helpful to have a discussion like this with your Sunnyvale tire pro when you need new tires. You can find the best solutions for your driving needs and to make improvements in ride or handling.
Picking a wheel that is the same size as what you are now running is pretty simple. But, it gets trickier if you want to upsize. Just get some help when you go bigger. All that tire and wheel still needs to fit in the available space. You do not want your tires to rub when you turn or hit a bump. You also need to make sure your brakes and suspension bits will fit with your wheel of choice. It doesn't matter how great your car looks if it's not drivable.
Taller, wider wheels and tires probably weigh more than your stock shoes. And it's "unsprung" weight - that has a big impact on brake performance. The upsized shoes increase rotational inertia - if you go too big you may need to upgrade your brakes to compensate.
Another possible problem is an inaccurate speedometer. This happens because the number of rotations can change with the new wheels. Fortunately, speedometers and odometers are all controlled by the engine computer; so it is simple to get it reprogrammed and compensate for the bigger tires.
No matter what you are after: low cost, long life, high performance, traction or stunning good looks, your wheel and tire professional at Deans Automotive, Inc. in Mountain View, California can help you identify your needs and give you a custom fit. With all the options available, you don't have to compromise. There is a tire out there with your name on it!

Professional Fuel System Cleaning
Posted February 7, 2012 10:58 AM
Getting enough fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean.
Today’s production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume.
You can buy fuel system cleaners that you just pour into your gas tank that can help maintain an already clean fuel system, but can’t do a major cleaning. For that, you need to see Deans Automotive, Inc.. They have the tools and chemicals to do the job right. Deans Automotive, Inc. can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.
You'll find Deans Automotive, Inc. at 2037 Old Middlefield Way in Mountain View, California 94043. Or just give us a call at (650) 961-0302 to schedule an appointment.
You’ll enjoy more power, better gas mileage and reduced exhaust emissions. The cleaners also help prevent rust and corrosion in your fuel system and lubricate vital engine parts.
And, as with all maintenance, it can help prevent costly repairs that can happen because you didn’t take preventative steps. Check with your service technician at Deans Automotive, Inc. and see when your car is scheduled for a fuel system cleaning.

Mountain View California Winter Prep Service For Your Auto
Posted January 31, 2012 2:15 PM
When winter approaches in Mountain View California, we break out the sweaters, coats, boots and mittens. We want to be ready for winter conditions. Your vehicle needs to be ready for winter as well. The last thing you want is to get stranded out in the cold. You need your vehicle to be safe and reliable. It's a good idea to get caught up on any neglected maintenance items anytime - but the stakes are higher in the winter.
There are some specific things that we need to do in Mountain View California to have our vehicle ready for winter. The most obvious is having the antifreeze checked. If the antifreeze level is too low, it can't properly protect your engine, radiator and hoses from freezing. If your car does not seem to be making enough heat to keep you warm, your antifreeze level may be low or you could have a thermostat problem. Get it checked out. If you are due for a cooling system service, now is a perfect time to have it done.
In the cold months around Mountain View we always worry about being able to stop in time when it's slick out. The first thing to remember is to slow down and allow yourself plenty of room to stop. Of course, you want your brakes to be working properly. A thorough brake inspection will reveal if the pads or any other parts need replacing. Check with your service consultant to see if it is time to replace your brake fluid. It accumulates water over time which really messes with your stopping power.
It is a really good idea to have your battery tested. A battery's cranking power really drops with the temperature. If your battery is weak in the fall, it may not be up to winter. There is nothing like a dead battery in a snow storm.
Which leads us to an emergency kit. You should always have a blanket or something to keep you and your passengers warm if you get stranded. If you will be venturing away from civilization, pack more items such as food and water to help you survive. Keeping at least half a tank of gas is a good precaution if you get stuck and need to run the car to keep warm and it will help keep your gas lines from freezing up.

Winter in Mountain View California always makes us think of our windshield wiper blades - usually during that first storm when they aren't working right. That's why it's a really good idea to replace your blades in the fall before the winter storms. If you live where there's a lot of snow and ice, you might want a special winter blade that resists freezing up. And be sure to have enough windshield washer fluid.
The final thing to consider is your tires. Any tire can lose pressure over time - up to one pound every six or eight weeks. For every 10 degrees the temperature drops you lose another pound of pressure. So if it was 80 degrees outside when you checked your tire pressure two months ago and now it's 40 degrees out, you could be down 5 pounds of pressure. That's enough to be a real safety issue and it wastes gas too. You may need special winter tires as well. Your tire professional can help you find the right tire design for your expected road conditions.
If you're getting winter tires, it is always best to put them on all four wheels. If you are only getting two, have them put on the rear - even if you have a front-wheel drive or four-wheel drive vehicle.
This is a very important safety measure recommended by tire manufacturers. Sliding or fish-tailing on ice and snow is a matter of not having enough traction at the rear end. That is why your newest tires should always be on the rear.

Questions To Ask Your Mountain View Service Advisor
Posted January 27, 2012 9:31 AM
We find that a lot of Mountain View service and repair at Deans Automotive, Inc. are a little tentative when they talk with their automotive advisors. They want to ask questions, but don't want to be embarrassed or to seem pushy. Cars are very complicated and there's more to know about them than most of us have the time to learn. Maybe it's because cars have become so much more reliable that the average person just doesn't need to know as much to keep their vehicle on the road.
You know, your local hospital has a Patient's Bill of Rights that they post throughout the hospital. We think our Mountain View automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.
It's all about the communication. It's a little harder when you're trying to find the right service center in Mountain View. But once you've developed a relationship, the communication should come easier.
What are some of the barriers to communication? Well, let's go back to the medical example. When your doctor's explaining something to you, it's something that she understands very well and is very familiar with. So she may use jargon you don't understand or that you don't have the education and training that's foundational to understanding what she's trying to explain.
So you fall behind and get frustrated.
It can be the same with your Mountain View automotive service advisors. Most of them are very busy trying to service and fix cars to get their customers back on the road. So, just ask when you feel you need more information.
Financial related issues seem to be most frustrating to customers. If you're not sure, ask what the payment policies are. For example, there's a big difference between giving your car a quick once over and doing a thorough inspection. Diagnosing a problem may take quite a while. Make sure you know what's done as a courtesy and what has a fee. Remember, you still have to pay for the office visit even if the doctor says you only have a cold.
Communication is a two way street. If you have some real budget concerns, ask your Mountain View service advisor what he can do. He can give you priorities and options. He can tell you what needs to be taken care of right away for safety or financial reasons. Then you can work out a plan for when to get the rest done. He can also help you with options on the parts. The preference is to always use a high-quality part with a reputation for reliability. But if money is real tight, he might be able to find a rebuilt part or a used part. He should tell you the difference in the guarantee for the part so you can make a good decision.
Ask about warranties for parts and labor. Be sure to get all the paperwork you need to make a possible claim in the future. Your service center and its technicians stand behind their work and want you to understand precisely what that means.
Be sure to ask for and keep a detailed explanation of all the work that's done on your vehicle. These records will help you keep track of service, warranties and document the good care your vehicle has received when the time comes to sell it.

Deans Automotive, Inc. On Your Serpentine Belt
Posted January 20, 2012 10:17 AM
Today we’re going to be talking about serpentine belts for our Mountain View California customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the device that makes electricity to power the vehicle and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you're driving around Mountain View California in the summer.
The power steering and power brake pumps are driven by the serpentine belt in most vehicles. Those pumps make the pressure that assists your steering and braking.
In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Mountain View California, the water pump is driven by the timing belt.
The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of work for one belt.
But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of work, but they’re tough and can last for thousands of miles.
Just how long will they last? That’ll vary for each individual car in the Mountain View California area. Your manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection can reveal a belt that’s getting close to failing.
Deans Automotive, Inc. can look at the belt: if it has more than three or four cracks per inch it needs to be replaced. A deep crack that’s more than half the depth of the belt - replace. Frayed, missing pieces, a shiny glazed look? It’s out of there.
What’s involved in replacing the belt? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.
This pulley is mounted to the engine block with a spring loaded arm. Its job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV recommends replacing them at the same time as the belt. It just makes sense.
What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating around our Mountain View California streets. A loose belt might give you a slow, slapping sound.
What do you do if your belt breaks? If you’ve actually had that happen on our local Mountain View California freeway, it can be a little scary. Often the first thing you notice is that you have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.
Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is very critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Pull over as quickly as you safely can. Open your windows and turn the heater on full blast to provide a little engine cooling and pulled over as soon as possible.
The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won’t run and will just shut off. You don’t want that to happen while you’re driving in our local Mountain View California traffic.
Remember, this does not have to happen if you replace your serpentine belt on schedule. Ask your technician at Deans Automotive, Inc. to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

Coolant Antifreeze Service In Mountain View California
Posted January 11, 2012 11:53 AM
You may know that most automotive failures in Mountain View California are tire related, but do you know the second most common cause for vehicle failure? Nope, it's not teenagers. It is the coolant system. But, if you take good care of your coolant system, it will take good care of you.
A car's engine creates a lot of heat - so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause engine damage. This could be very expensive, not to mention inconvenient.
The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to remember is this: coolant system failure is very common, but it is also very easy to prevent. Your Mountain View service center knows the manufacturers' recommendations, and can tell you when the coolant needs to be changed. They can also perform a coolant system service.
Give us a call or stop by for a coolant service or checkup.

Even the best antifreeze cannot completely protect the coolant system from harmful deposits forever. The anti-corrosion additives are used up over time, so the coolant must be replaced. A coolant service cleans out the system and replaces the old fluid with fresh coolant. A coolant system service is a low-cost way to protect against major engine repairs down the road. Prevention is the key. Be sure to watch out for the two main warning signs: if your temperature gauge is in the "hot" zone or if you get a message warning you to check your coolant. If you take a look under the hood, you will see the coolant overflow bottle. You can see there are lines that indicate the proper level of coolant ... if your engine is cold - or if it is hot.
You can add water or antifreeze to that bottle yourself, but be careful. First, you never want to open the radiator pressure cap. The steam could severely burn you. Second, try to get to your service center immediately if your coolant is low. If that is not possible, follow the directions in your owner's manual. Third, remember that you need a proper mixture of water and antifreeze, or you will damage your engine. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.
You will need to check your owner's manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. If you're not sure, ask your service technician at Deans Automotive, Inc. for guidance.

Tire Tread Depth for Mountain View California
Posted January 4, 2012 9:53 AM
So, when are your tires actually worn out? This is a question a lot of us in Mountain View California ask ourselves. For many, the answer is 'when they no longer pass a safety inspection'. But waiting that long can have a serious impact on your safety.
The U.S. Federal government doesn’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Deans Automotive, Inc. (just call (650) 961-0302) to find out what your requirements are in the Mountain View California area.
Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give you enough safety?
Well, Consumer Reports issued a call to consider replacing tires when tread reaches 4/32”. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the big issue is braking on wet surfaces.
We tend to think of the brakes doing all the stopping, but you also need to have effective tires to actually stop the car. When it’s wet or snowy in Mountain View California, the tread of the tire is critical to stopping power.
Picture this: you’re driving over a water-covered stretch of road. Your tires actually need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is actually contacting the road and not floating on a thin film of water – a condition known as hydroplaning. When there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.
This is where the studies come in. We think you’ll be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to cover it.
A car and a full-sized pick-up truck were brought up to 70 mph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32” of tread were tested – this is the depth suggested by Consumer Reports
When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph with the worn tires.
Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph at the point where new tires brought the car to a halt. That’s a big improvement – you can see why Consumer Reports and others are calling for a new standard.
Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile of clear road ahead to come to a safe stop. Obviously this is really a big safety issue.
The tests were conducted with the same vehicles, but with different sets of tires. The brakes were the same, so the only variable, was the tires.
So, how do you know when your tires are at 4/32”? Well, it’s pretty easy. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.
Now you may remember doing that with pennies. But a penny gives you 2/32” of an inch to Abraham Lincoln’s head. The quarter is the new standard – 4/32”.
Tires are a big ticket item and most people in Mountain View California want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out? For us, and we would guess for many, the answer is “no”.
Well, Mr. Washington, let’s go out and look at my tires.

Timing Belt Replacement in Mountain View
Posted December 30, 2011 12:24 PM
Today we want to talk about timing belts. They’re something that many Mountain View drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most Sunnyvale car owners remember because it’s not well understood.
Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.
Now, not all los altos and pallo alto vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we're left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.
Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost thousands to repair the engine.
So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from Deans Automotive, Inc. may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it’ll cause. There’s no middle ground.
So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Deans Automotive, Inc. service advisor right away if your manufacturer requires a timing belt replacement.

Sometimes you can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.
What does it cost to replace a timing belt in pallo alto or sunnyvale? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the damage caused by a failure.
At Deans Automotive, Inc. we’re all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

Odometer Rollback On Your Mountain View California Auto
Posted December 21, 2011 1:22 PM
How do you know if an odometer is telling the truth?
Well, back in '86, Congress passed the Truth-in-Mileage Act to protect California consumers against mileage fraud. It says a California seller must certify the mileage reported is the Actual Mileage.
To have your odometer checked in Mountain View California, stop by Deans Automotive, Inc.:
Deans Automotive, Inc.
2037 Old Middlefield Way
Mountain View, California 94043
(650) 961-0302
If it isn't, the seller must say why; like maybe the odometer is past its mechanical limits. Some older odometers only go to 99,999 miles and then start over at 0. Or, the odometer has been tampered with, broken or replaced.
If the seller tells you the mileage isn’t accurate, there’s not much chance of putting a good number to it; And there’s the unscrupulous seller who claims the reading is true, but it’s not so. What can you do?
First, you can go to www.CarFax.com, where for a small fee, they’ll give you a comprehensive vehicle history search on your Honda, showing local Mountain View California ownership history, accident reports, total-loss events, Manufacturer buybacks, Lemon reports and warranty status.
You can get a mileage history by checking with the local Mountain View California DMV (or wherever you happen to be) and other verified sources looking for inconsistencies in the mileage reported when the car’s bought and sold. If there are signs odometer rollback, now you’ll now.
If so, proceed with caution. Or, negotiate a lower price. Or just walk away. There’s always another.

Tire Replacement: What pallo alto Drivers Need to Know
Posted December 13, 2011 1:33 PM
Looking at getting some new tires? The choices at pallo alto tire stores can be a little overwhelming. Suppose you have an SUV and are trying to decide between all season tires or some that are also rated for off-highway. Do you get off the payment on the outskirts of pallo alto more than most? If so, some additional off-road traction would be nice.
Maybe the real reason for wanting those off-highway tires is that they look cool. Well there’s nothing wrong with that. If you make sure that you’ve got your functional needs covered with your selection, then you can have some fun with where you go from there.
Let’s suppose you zip around pallo alto in a sporty car. You may like to run a high-performance summer tire when the weather’s good. When California weather turns cold, you can put on high-performance winter tires. For the kind of driving you like to do, you want full-on performance tires. All-season tires are naturally a compromise that works well for most pallo alto drivers, but since you have a choice, go for dedicated summer and winter tires.
When it’s time for new tires, visit with a knowledgeable Deans Automotive, Inc. tire professional. Describe your needs and wants. He’ll come up with some selections for you to discuss. And once you settle on a type of tire, there are options for special needs: like pulling a trailer or carrying heavy loads.
Tires are one of the biggest purchases for pallo alto drivers. With so many choices, you’ll be able to get what’s best for you. Take their time. And don’t worry about what’s in stock. If you want something that isn’t here at Deans Automotive, Inc., manager Warren McCord can order it. Chances are you’ll be rolling on your new tires in a couple of days.
