San Diego Auto Repair

With the recent focus in Mission Valley on improving fuel economy, we've been told how important it is to maintain our tire pressure. Everyone in Mission Valley knows that tires wear out, but we all want to make them last as long as possible because they're fairly expensive to replace. In addition to saving gas, properly inflated tires last longer. Under-inflated tires will wear out more quickly. Some people in Mission Valley wonder if there is benefit to adding a few extra pounds of pressure when they fill up their tires. But actually, there isn't. In fact, there are very good reasons not to over-inflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling. Every vehicle in the Mission Valley area has a sticker on the driver's side door jamb that tells you the manufacturer's recommended tire pressure. This recommendation is an integral part of the vehicle's suspension tun ... read more

Today we want to talk about timing belts. They’re something that many San Diego 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 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 ... read more

Today we’re going to be talking about serpentine belts for our 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 San Diego CA 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 San Diego CA, 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 desi ... read more

We live in such a disposable society. It's amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough - they had to do without. Most people couldn't afford new cars very often, so they had to make them last as long as they could. It's a good thing that cars are more reliable these days. They just don't break down as often. And the good news for us CA penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us San Diego car owners making sure we follow the manufacturer's recommended maintenance schedules. Extend Vehicle Life with these Simple Tips Every time you go a couple thousand extra miles between a car oil change, you ... read more

Is your car sometimes hard to start? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your car's fuel system starts with the car air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy. Most of today's cars have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system. Some CA drivers are interested in buying fuel system cleaners that you can pour into your gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning ... read more

Hey San Diego, are your tires worn out? What is the standard for our CA streets? How can you tell on your sedan? While there may be legal requirements for the San Diego area, there are safety concerns that go beyond meeting minimum replacement mandates. 2/32 is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently. We're referring to the Consumer Reports call to consider replacing tires when tread reaches 4/32 of an inch, or 3.2 millimeters. And the recommendation is backed by some very compelling studies. The issue is braking on wet surfaces in and around San Diego. Most of us think of our brakes doing most of the work, but if you don't have e ... read more

At Convoy Auto Repair we’ve had a lot of people asking how they can make vehicles last longer. These questions are actually a reflection of a trend that’s been building for several years. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles on them. It looks like it’s going to keep heading in that direction for a while. With high fuel prices a lot of folks are putting off buying a new car. Thanks to AutoNetTV, we can provide you with a video answer to this question. So let’s say you’re one of the average people in San Diego; you’ve got a nine year old car with 80,000 miles on the odometer. What can you to do make it last another year or two? Let’s start with the premise that there’s no reason that a modern car can’t run for 200,000 miles with proper care. The engineering and manufacturing quality is there. Of course, some parts will wear out alon ... read more

At AutoNetTV we love doughnuts. So let's pretend you have three doughnuts right in front of your for our discussion of upsizing wheels and tires. Hey, don't eat them now - your going to need them later. Many people want to accessorize their car - you know, make it theirs. One of the easiest ways to get a custom look is to get some new wheels. There are thousands of wheel designs out there to get you the look you want. And for many, that look includes bigger wheels. It used to be that cars came from the factory with 15 or 16 inch wheels. Now 16, 17 and even 18 inchers are standard. And the factories are offering optional wheel packages up to 20 inches or more. So let's talk about what to consider when you want to upsize your wheels. It's not exactly a do it yourself project, so you need to know a thing or two before you get started. The most important term to know is rolling diameter. The rolling diameter is simply the overall ... read more

We live such busy lives nowadays: work, social events, running the kids all over San Diego. Some days, it’s all we can do to keep track of everywhere we need to be. That’s why you’ve gotta be organized. Lists, PDA, calendar- we have to keep track of it all. So let’s talk about schedules. Specifically, automotive service schedules. And particularly, the scheduled services that are sometimes forgotten. We have a list of 10 service items that are often overlooked. They’re all very important and need appropriate attention. So here we go, in no particular order. 1. Power Steering Service Be honest; have you ever thought of this on your own? Your power steering fluid gets dirty and builds-up moisture over time. Cleaning out your power steering system means that dirt and gum are removed and your power steering parts are protected from corrosion. Ask your service advisor if it’s time for a power steering check-up. 2. Wheel Alignment When your wheels are out o ... read more
