Today we want to talk to San Diego drivers about timing belts. They're something that many 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 San Diego area auto owners remember because it's not well understood.Let's review what a timing belt does. As most 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 open ... read more

If someone tells you to put the brakes on something, you know it means stop.  And stopping is one of the most important safety maneuvers you can do in any vehicle.  That means your brakes have to work properly.  Let's face it.  You stop dozens of times every time you drive.  And over time, that takes its toll on your brakes.  Friction is what stops your vehicle.  Most newer vehicles have disc brakes, and the parts that wear out the fastest are those that rub against each other every time you stop, the rotors and the pads. The rotors are discs that rotate with the wheels, and the pads are removable surfaces that make contact with the rotors to slow or stop your vehicle.  Bits of both wear off each time you stop, and when enough of either (or both) lose too much material, your brakes become unable to safely slow or stop your vehicle.  The pads usually are the parts that wear out first.  Signs that your brakes might be getting worn are: Y ... read more

Let's talk about deciphering the auto service menu board. San Diego, CA, service centers like Pacific Highway Auto Repair have a board that lists the routine services they provide.

You may notice that when you get your vehicle's oil changed, your service adviser may recommend that you have your tires rotated at the same time.  The reasons are simple.  That will allow your tires to wear more evenly and reduce the noise your tires make as you drive down the road. There are different ways of rotating tires. If your vehicle has non-directional tires and the same size wheels at each corner, here are the different rotation patterns. For all-wheel drive and rear-wheel drive vehicles, one is called the rearward cross pattern.  The rear tires are moved to the front and stay on the same side of the vehicle, and the front tires are moved to the rear on the side opposite of where they were on the front.  For all-wheel and four-wheel drive vehicles, use the X pattern.  The rear tires are moved to the front on the opposite side of the vehicle, and the fronts are moved to the rear on the opposite side of where they were on the front. For front-wheel dri ... read more

In warm weather, you want to be in a cool vehicle. When we're talking cool, we don't mean stylish or trendy, but cool as in not sweltering inside.  And if your vehicle's air conditioner stops working correctly, it seems to always break at the worst time—during a heat wave.  Automotive air conditioning problems fail for a number of reasons: Blower motor not working.  No air comes through the vents, even though the rest of the system could be working fine. Refrigerant leak. When the gas that cools the air off escapes from the air conditioning system, your air conditioner can no longer cool off the outside air Condenser and compressor. These are parts of your AC system that compress and expand a refrigerant gas to cool off the outside air. They are fairly complex. When you bring your vehicle into our service center, we'll run a series of diagnostic tests to figure out what isn't working correctly.  The air conditioning system has a lot of parts. There are elect ... read more

Every time you drive your vehicle, you wear down your brakes just a little bit.  And after a while, that adds up.  Gradually, your stopping power isn't like it used to be.  Since brakes are one of your vehicle's most important safety features, it just makes sense to keep them performing well. Most vehicles have disc brakes.  One key component, as the name suggests, is the disc.  Most vehicles have discs on their front and rear wheels.  The discs (also called rotors) are made of metal, and each rotates with the wheel hub.  Your brakes also have pads that make contact with the rotors when you press down on the brake pedal, and the friction stops your vehicle. After many, many stops, that friction wears down both the pads and the discs and reduces their ability to stop the way you need them to.  The discs may also become uneven from all the heat they generate, and your brakes won't stop as well as they used to when they were newer.  Some signs ... read more

When you get in your vehicle, how does it smell? If it's not so nice, it may be time to have your cabin air filter changed. It's not the same one that filters out the air used in the engine.  The cabin air filter screens out dust and other particulates from the outside air so when it enters the cabin, you don't have to breathe them in when you're driving.  Maybe your commute finds you traveling along dusty rural roads, or maybe you pass by some city factories that have smokestacks spewing out smoky exhausts.  Or in spring, maybe you notice your allergies acting up because of the pollen in the air.  The cabin air filter will remove a lot of those things. The more it filters out, the more those small particles add up.  That reduces how much airflow the heating/air conditioning system can handle, and you may notice not as much air is coming through your vehicle's vents.  That can also be a sign you need your air filter replaced. Our technicians will remove an ... read more

All modern San Diego vehicles come with fuel injection systems, so it's a topic San Diego drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in San Diego, CA. Some vehicles have 10 or 12 cylinders.

You probably figured out those shifty letters.  They're what you see on your automatic transmission shifter and stand for Park, Reverse, Neutral, Drive and Low.  Your automatic transmission is one of the great automotive inventions; here are some ways you can keep yours working well. Maintain your transmission regularly.  A technician will check your transmission fluid's level and even its appearance and smell.  If it's dark or has an unusual odor, that could be a sign of trouble. Change from one transmission direction gear into another only when your vehicle is stopped.  So many drivers want to switch from Reverse to Drive quickly or the other way around.  If you do that when the vehicle is moving, you can damage your automatic transmission. Keep your vehicle's cooling system in top shape.  What does the cooling system have to do with the transmission? It helps keep the transmission fluid from overheating.  Follow the manufacturer's recommendati ... read more

Every day you drive, you're sitting behind the dashboard. But how in the world did it get that name? Back in the days of the horse-drawn carriage, horses would kick up dirt and mud on the driver and passengers, "dashing" debris against the carriage. So those who built carriages began installing a board to protect them. So, dash-board. Dashboard. The dashboard is still there, though changed quite a bit from the early days. Now its main purpose is to house the controls and instruments for your vehicle's systems. Of course, you have the speedometer, tachometer and gas gauge. But there are four warning lights you need to pay attention to on your dashboard and instrument panel. Some of these may even be gauges, depending on your model of vehicle. Regardless, paying attention to them is a good idea if you want your vehicle to keep going as long as possible. Oil pressure—The oil pressure light will come on if your engine doesn't have enough pressure in its system. Low oil pressure means ... read more
