Los Altos Auto Repair

If you start me up, I'll never stop, so the lyrics go to the Rolling Stones: "Start Me Up."  Hi Cayenne here and well that's all good until your car doesn't start.    So yes, today we are going to start you up about ignition systems.  Let's get barkin'!

When you start up your gasoline engine car, you may not know it's using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval, which is called timing.

The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage was then sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid-state ones, but they still needed replacement after 120,000 miles/200,000 kilometers.

The next evolution came in the 80's when the distributor was replaced with a couple of sensors that talked to a computer.  This "DIS" (distributor-less automotive ignition system) was a big advance.  Plus, it didn't use just one ignition coil for all the cylinders.  It had coil "packs" that each provided spark to two cylinders.  That way, the voltage could be boosted even higher, to 30,000 volts, which helped engines be able to ignite a leaner fuel/air mixture.

Even more improvements have recently come. Now, instead of coil packs, a coil is attached to each spark plug. No more spark plug wires means less maintenance. Plus, a stronger, hotter spark of 50,000 volts can make an engine more reliable, increase fuel economy, and reduce emissions.

No matter what ignition system your vehicle uses, your vehicle service facility has a staff of technicians trained to work with the latest technology. Make sure to maintain your vehicle regularly so you can fully take advantage of these modern engineering marvels.

Now that you have all the information, maybe these lyrics will stick.

Cayenne here, and you've heard the saying "get back to the daily grind," but what if the daily grind is your vehicle?????  Well, today, we will grind our way into barking about the question.  

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you.  No, it is.  So listen to what it's saying and you could avoid a much more costly repair down the road.

A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on.  One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels.  Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. 

Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening.

Other causes of grinding while turning can be problems with the suspension in the front.  You may have a failing CV (constant velocity) joint.  It could be your brakes are partially engaging while you are turning.  That metal-on-metal sound is never a sign that things are working just the way they're supposed to.

To a technician looking to pinpoint the problem with your vehicle, it's not a daily grind at all.  Experience and training will help her or him zero in on what's causing the noise and get you back on the road. Maybe you can enjoy your sound system more after that distracting background noise has disappeared!

I leave you with this quote about the "grind"

"Nothing can substitute for just plain hard work."

Happy Holidays everyone, Duke here and you know dogs can see better than humans even at night.  Our visibility to detect small and large creatures running around at night is amazing but you, not so much. You've all been through it. The vehicle ahead of you kicks up mud, slush, snow or salt on your windshield and you can't see a thing.  And not being able to see a thing when we're driving?  Not a good thing.  So today, we will bark out the importance of having visibility by cleaning the glass on our vehicles. Let's wipe away the dirt and get barkin'!

Debris on a vehicle's glass can be blinding when driving directly into the sun.  Other things can ruin visibility: scratches on the glass, fogged windows, and mineral deposits. 

So let's make one thing clear:  Your windows.  Here are some tips.

• Number one rule, don't use abrasives on glass. That means no gritty cleaners that are made of metal.  Avoid at all costs those dark green abrasive pads on some kitchen sponges that are made to clean metal pots and pans UNLESS the manufacturer specifically says they can be used on glass.
• Use the appropriate cleaner for the substance that's being cleaned off. Special automotive glass cleaners are available, and your Allied Auto Works service advisor can make recommendations.
• Vinegar can work wonders. Sometimes you'll see hard, grayish water spots on your windows that nothing seems to take off. Distilled white vinegar (available in the grocery store) gets rid of them safely, quickly and easily.
• Use a microfiber cloth designed for cleaning glass; that's what professional detailers choose.
• Clean the insides of windows, too. That film that develops on the inside of vehicle windows can be the result of plastic interior surfaces decaying in the heat of sunlight (plastic contains oil). The film can also be caused by cigarette smoke. Clean that oily layer off thoroughly.

Now that you have clean windows, here's how to keep 'em clean.

• Replace your wipers at least once a year. Rubber deteriorates the older it gets, even if you rarely use your wipers.
• You might consider a newer type called a "beam" blade. Most have an aerodynamic design that cleans your windshield better, especially at higher speeds.

Your service advisor at Allied Auto Works will be able to recommend good wiper blades for your vehicle and install them properly.

Visibility.  See what we mean?  Now where did I see my bone last??

Happy Holidays to all,

Duke

Hello, Cayenne here today.  TPS......hmmm, that sounds like it stands for Tender Porterhouse Steak.....yummy.  No, don't be silly and wishful.  What it really stands for is Throttle Position Sensor.  Yes, I know it's not as tasty sounding, but it's very important to your vehicle.  So today we will bark about what TPS is.  Let's get barkin'!

You know you have an accelerator pedal; step on it, and your vehicle is supposed to go.  But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS.

The TPS is a sensor that helps your vehicle determine the right mix of air and fuel reaching your engine.  It does that by keeping track of the throttle and sending that information to your vehicle's computer.  Other factors affect how well your engine is performing, including air temperature, how fast the engine is turning over and air flow. 

When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator.  In some cases, it may accelerate on its own.  Sometimes, your vehicle won't go over a certain speed.  Your Check Engine light may go on.

Any of these symptoms should be checked out soon. If your TPS stops working right, your vehicle may not be safe to drive. Fortunately, most vehicles have a "limp home" mode that allows you to get off a busy road and to a safe spot. 

Your service advisor can tell you which TPS is the correct replacement for your vehicle. Your shop may have to re-program the new TPS so it works correctly with your vehicle's software.

It's a fact of life these days that computers control many of a vehicle's functions. The sensors that feed information to those computers help make your vehicle work how it was engineered to and keep you motoring safely and efficiently down the road.

As we move into Winter, I leave you with this,

It's Thanksgiving week, and the delicious smell of turkey is awaiting me. Hi, Cayenne here and you know I love the smell of turkey coming out of the oven, but have you ever had an awful smell coming from inside your car? Rotten egg smell, yuk, and today, we will bark about what that horrible odor is.  

The pungent smell of rotten eggs can send people running for the hills, so when that odor is inside your vehicle, yikes! Yolks! The good news is that a trained service technician can locate the source of that smell and stanch the stench… that comes from another word that begins with S.  Sulfur.

Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs often signals a catalytic converter that isn't working as it should.  That could be due to age, damage or an abundance of oil clogging it up. 

If a sensor in charge of managing the fuel fails, the engine can run with a fuel mixture that is too rich.  That can overload the catalytic converter and allow some byproducts to escape without interruption from the chemical reaction that prevents them from going out of the tailpipe.

There's another possibility, but it's usually only found in stick-shift vehicles. That's leaking old transmission fluid.

Catalytic converter repairs are best left to a professional. Technicians at your vehicle service facility have equipment and training that can help them pinpoint the cause of this funky fragrance. Once the cause is found, repairs are made, and/or parts are replaced, and the smell should go away fairly rapidly.

Now, let's start talking about the smells I do love: turkey, pumpkin pie, and sausage stuffing......I can go on

Happy Thanksgiving,

Cayenne

Brrrr, it's cold this morning in California. The seasons are definitely changing. Duke here and when I am in the car for a ride, I sometimes look in the rearview mirror and notice objects appear to be close. You may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving.  So let's open our eyes and start barkin'!

While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you.  There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors.

It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are.

Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, you'll never be sure they're pointed in the direction that will let you see where traffic is.  The one on the windshield must be firmly attached.  If it won't stay where you want it, head to your service facility, where they can tighten it or replace any parts necessary to let the mirror maintain its aim. A technician can reattach it with the proper adhesives or fasteners if it has fallen off the windshield completely.  There may be electronics that need to be properly connected as well.

The outside mirrors cover your blind spots and they must be able to hold their adjustments, too.  Many adjust electronically; switches and motors can fail, electrical connections can detach or become corroded and the reflective glass can crack, discolor or develop a hazy fog.  A technician can diagnose and repair those problems and recommend any replacement parts you might need.  Mirrors that are adjusted manually should also be restored to proper working order for you to maintain this essential rear visibility.

Drivers don't think about their rearview mirrors all that much.  On reflection, don't they deserve respect and care for the important job they do?

"Life is a mirror: if you frown at it, it frowns back; if you smile, it returns the greeting"

Good Day, everyone. Cayenne here.  Do you know what TPS stands for? No, it's not Tender Porterhouse Steak, even though that sounds good to me. It means Throttle Position Sensor. Yes, I know it's not as tasty-sounding, but it's very important to your vehicle.  So let's get barkin' about TPS.

Cayenne here today. Everyone loves things that sparkle. Our vehicles send out their own spark through the ignition coil.  But how do you know it might be time to replace the ignition coil?  Well today we will ignite you some sparkling information on the subject.

Ever wonder how your vehicle’s engine can take the 12 volts from its battery and ramp that up to as high as the tens of thousands of volts it takes to fire its spark plugs? The secret is something called an ignition coil. Most newer vehicles have an ignition coil at each cylinder, but older ones have one that serves all the spark plugs. 

There are telltale signs that you have an ignition coil problem. As you might expect, one symptom is that it’s hard to start your engine or that it won’t start at all. If your engine is misfiring or not running smoothly, or you see the Check Engine light come on, those could all point to an ignition coil failure.

Several things can contribute to ignition coil trouble in addition to normal wear and tear. Moisture and dirt may have gotten inside the coil, and the heat and vibration of your engine over time can cause it to go bad. Bad spark plugs or plug wires can also be a cause.  

While ignition coils can last 100,000 miles/160,000 km, depending on how you drive and in what conditions, if you start noticing some of the signs and symptoms just described, it’s a good idea to schedule a visit to see us so a technician can diagnose what’s wrong. Driving too long with an engine misfiring can damage your catalytic converter, which can be expensive to replace.

A technician will thoroughly check your ignition system and determine where the failure is. If only one coil is bad, it may be the only thing that needs replacing. If your vehicle has a distributor, it may also need replacing. Properly working ignition coils will help your vehicle operate at its best and help prevent future engine damage.

Leave a little SPARKLE wherever you go,

Cayenne

Hello South Bay residents!  What a beautiful day here in California.  Take a nice car ride with the windows down and the wind in my face.  But wait, you may be driving along and find that suddenly your radio stops working.  There are no numbers on the display.  Then, when you get home, you notice the garage door opener doesn't do a thing when you press the button. Hmm, this was working just fine this morning.  Are the two problems somehow related?  Let's start barkin' and find out!

No, your vehicle doesn't need an exorcism. This has all the signs of an electrical issue, and when you experience symptoms like those, you've probably blown a fuse.  Most vehicles have fuses, just like most houses have circuit breakers (some houses still have fuses). They cut the power when it reaches a pre-determined threshold that could cause major damage if it was allowed to continue.  You might say fuses take one for the team.

Most modern automotive fuses are plastic with a thin strip of metal in them designed to melt when a calibrated amount of power passes through.  The philosophy is it's better for an inexpensive fuse to be destroyed than your sound system or your engine's main computer.

It can be tricky to figure out what fuse has blown and why.  Modern vehicles have many computerized electronic components; they can easily be damaged if too much electricity gets to the wrong spot.  At Allied Auto Works in Los Altos, we have technicians trained to trace which fuse has blown and why.

While sometimes a simple fuse replacement will fix the problem, other times, some other electrical components may have failed, causing the circuit to overload. Our technicians have special equipment to track down where the power problems are, get to the root of the problem, and fix it at the source.

Keep in mind that fuses are there to protect your vehicle. When they shut down your radio, garage door opener, vanity mirror, or anything else, just be thankful they're doing their job. They may have saved you from a much more expensive repair. They've sent an important signal to you about your electrical system. That's why it's good to keep up with "current" affairs.

I leave you with this thought today,

Duke here. Who thinks about their fuel gauge? You probably don't… until it doesn't work anymore. Then you have to guess how much fuel is in your tank, and that's no way to live life on the road. Imagine how upset the hounds will be if they don't get their car ride. So today, we will be barkin' about fuel gauge problems and what to do. Let's get barkin'!

Fuel gauges, like every other part in your vehicle, can fail.  When yours stops working, you will probably want to head over to your service facility soon because no one relishes running out of fuel.

The fuel gauge system is much more than just the gauge on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level. It's called the fuel-sending unit, and it sends an electrical signal to the gauge (on the dash), telling it to display how much fuel is left in the tank. 

So, what could go wrong? Well, a few things. For one thing, corrosion from bad fuel can cause it to stick, and it won't move up and down anymore. So you could fill up your tank, and the gauge would still read Empty. If a sending unit needs to be replaced, the parts can be costly. The good news is that fuel-sending units rarely fail, and most drivers will never have one go bad.

Other things that can go wrong? An electrical problem could cause a fuse to blow and you won't get a reading at all.  A technician can figure out where that electrical problem is and how to repair it.  Finally, it's possible for the gauge itself (on the instrument panel) to fail.

One thing to keep in mind is if your fuel gauge isn't working, you might be tempted to carry around an extra container of fuel.  That's ok if it's outside the cabin, such as in the bed of a pickup.  But if you carry it inside the cabin or trunk, fuel fumes can be very dangerous for your health, even fatal.

A working fuel gauge gives you peace of mind… so you'll never have that "empty" feeling.

I leave you with this thought,
