There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle.  A lot of us are quick to blame the battery.  But it may instead be your alternator that's failing. Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running.  The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment. Alternators have bearings inside them that keep things turning smoothly.  Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up.  That's not good, and if that happens, you may even be able to hear the bearings grind. Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright.  You might even notic ... read more

Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and San Diego drivers couldn't wait to get them off the car. Then along came television advertisements for “all-season” radials. CA drivers ran out and bought some and we thought we were done with snow tires forever.Tires have come a long way since then. Modern winter tires sold in the San Diego area are much better designed for the wide range of conditions that come with CA winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at San Diego temperatures below 45°F (7° C) which reduces their traction. That's a concern in winter, especially with snowy or wet conditions. But it also means that San Diego drivers are better off with winter tires in cold weather even when it's dry.The tread design on winter tires has been improved to move snow, slush ... read more

A lot of fuel is wasted in the San Diego area by dirty fuel delivery systems in vehicles.Let's start at the tank. The gas tank gathers dirt, rust and sediment over the years. That's why there's a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently.The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at Pacific Highway Auto Repair will leave your intake components as clean as a whistle.The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they're clogged, the fuel doesn't get atomized the way it's supposed to and doesn't get burned as efficiently.See your owner's manual or ask your San Diego service advisor at Pacific Highway Auto Repair when a fuel sy ... read more

Differential? What's that? And what's it for? I've been told by my service advisor that I need to get it serviced, but is that on the level?Do these questions sound familiar? They're not uncommon for San Diego drivers. A lot of us in San Diego don't know what a differential is or what it's for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it's more important to the operation of your vehicle than the air conditioner or windshield wipers.A differential allows your vehicle tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.The location of your differential depends on what kind ... read more

It's easy to get letters like PVC and PCV mixed up.  PVC is a plastic that's used in a lot of things, especially plumbing pipes.  And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere.  PCV stands for positive crankcase ventilation.  When your engine ignites gasoline in the cylinders, some of the gases produced make their way into the crankcase, where oil is held to lubricate the engine.  In earlier days, those gases would be vented out through a hose and go directly into the air.  It was a waste of gasoline (since about three-fourths of the gases were unburned fuel) and a nasty source of pollution. So engineers devised a one-way valve that directed those gases back into the engine's air intake system to be burned again.  After a while, the PCV valve can get clogged up with gummy oil.  Not only does that reduce the recirculation of the gases, but it can also cause pressure in the crankcase ... read more

Of the things you think about most, your tires are probably pretty far down the list. That’s understandable because today’s tires are engineered to do their job without needing you to pay too much attention to them. But they DO wear out, and worn tires can contribute to skidding in bad weather, not being able to stop, a ride full of uncomfortable vibrations and, even a sudden blowout. Yikes. Let’s figure out right now how to know if your tires need replacing! Let’s face it. Most of us don’t know the first thing about tires. So, the best way to make sure what shape yours are in is to take your vehicle to a qualified service facility to have the tires checked out by a trained technician.  Here are things they’ll check: Tread.  Tread is the part of the tire that touches the road surface.  Different tires have different tread patterns and something called tread blocks - the raised rubber parts that contact the road. The longer a tire has ... read more

If your vehicle isn't starting or doesn't sound like it used to when you crank it, the culprit may be the battery.  You may have left a light on, or something plugged into one of charging ports.  Maybe you accidentally left your vehicle in the "on" or "accessory" position when you last got out. Maybe you've left it in the garage or driveway for a long time without starting it.  That can spell the end for a vehicle battery. It's also possible that your battery is just simply too old. There's no standard lifespan of a battery, but 3-5 years is about average, even though some people only get 2 and heavier duty batteries may last many more. It's possible your battery is defective, too.  And it could be your vehicle's charging system isn't recharging the battery.  Whatever the cause, if you're having problems with your battery, it's a good idea to bring it in and have us perform a thorough battery test.  With state-of-the-art testing equipment, a technician wil ... read more

Something you're going to be hearing a lot about around San Diego, CA, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.Most people in CA are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in San Diego, CA. But that's about to change.In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in San Diego, CA, so we are now ready to start seeing more diesel options offered over the next few years.Why are so many San Diego drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. There's more power in a barrel ... read more

As the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there's one more component to keep an especially sharp eye on during winter: your alternator. The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys.  In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move ... read more

You swap your winter boots for flip-flops in the summer.  Why not change your winter engine oil for summer, hot-weather oil?  While it may seem like it makes sense, there's some good news.  Most drivers don't have to, and here's why. Engine oil can be made in different thicknesses.  That thickness is called viscosity, how easily it flows.  Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well.  So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather.  While there was a time when oils could be only made in one viscosity, times have changed.  Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls.  It self-adjusts to match the conditions.  Now that's what I call a great invention. In most temperate climates, you don't have to swap out the type of oil you use ... read more
