Using Proper Fluids In Your sedan Or Other Vehicle

Today Convoy Auto Repair is talking about the proper fluids for your vehicle. It's become more complicated with changes in automotive design and manufacturing. It's not that people in CA are confused as much as they don't realize how much things have changed in recent years. Let's take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness. It was common in those days to use a lighter weight oil in the winter when it's cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn't thin out too much in the summer heat and vaporize in the engine. Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine ... read more

Winter Tires

What type of technology do you use? Do you prefer an 8-track tape or an iPod? When it comes to winter tires, much of the public's perception dates back to when 8-track was the best way to listen to the Bee Gees. Twenty years ago, winter tires differed from highway tires only in their tread design. We called them snow tires back then and they had big, knobby lugs that were designed to give good traction in deep snow. They had the same rubber compound as regular tires and they weren't very good on ice, packed snow or wet roads. They were not even very good on dry roads. They really helped in deep or loose snow, but they did a poor job the rest of the time. They were loud and rode hard. You couldn't wait to get them off in the spring. Then all-season tires started to come along. All-season tires are really a compromise between summer and winter performance. They have acceptable hot weather ride and tread life, and you can get through mild winter road conditions OK. But there are ... read more

Keep it Flowing With A Fuel Filter Replacement At Convoy Auto Repair

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around San Diego CA use fuel filters. Generally speaking there's not a lot of dirt in our San Diego CA auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That's because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your sedan is five years or older, it can actually have a fair amount of sediment built up. That just means that the fuel filter has to work harder as your sedan ages. It'll get clogged sooner and need to be replaced more often. A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That's because enough fuel is getting through around town, but when you need more fuel for speed, enough ... read more

Emergency Items For Your sedan

Your close-to-home kit for around San Diego would have some basic items to work on your car: everything you need to change a tire, gloves, a couple quarts of oil, some antifreeze and water.

Recommended Service Intervals

Everyone in San Diego knows we're supposed to go to the dentist twice a year. We get our teeth cleaned and have a thorough dental inspection. Once a year, we get x-rays to look for problems that can’t be seen with the naked eye. When the dentist is done, he tells us what he’s found – “Everything’s fine, see you in six months.” Or “You’ve got a small cavity starting, let’s schedule an appointment to take care of it.” By the time you leave, you have a plan for addressing any necessary repairs. This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills. If we buy into this way of handling our dental care, why do we resist so much when facing the same system for our car care? Following the manufacturer’s recommended intervals can be confusing. First there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steer ... read more

Risk of Extended Oil Change Intervals

Nothing in your engine workers harder than your oil. With hundreds of moving parts, and thousands of explosions every minute, it's no wonder that engine oil needs to be changed frequently! You've probably heard the old rule of thumb: Change your oil every 3,000 miles/ 5,000 kilometers or 3 months, whichever comes first. But some car manufacturers have introduced extended car oil change intervals. They figure that a modern vehicle driven under the right conditions can go for 5,000 miles/8000 kilometers or more between an oil change. The key phrase here is "under the right conditions". If you look at your owner's manual, you'll see two different maintenance schedules: one for "normal" driving conditions and one for "Severe Service". Severe service driving conditions include stop and go, short trips, towing, hauling, hot, cold, and dusty driving. That's why at AutoN ... read more

Headlamp Replacement

Like everything automotive, there have been great strides in headlight technology in recent years. We can all drive more safely at night because of it. Good headlights improve visibility down the road, enabling you to see farther. They also improve your peripheral vision, helping you to see the sides more clearly. The more you can see, the quicker you can react to road conditions. This is important because nearly half of traffic fatalities take place at night. And as the country's population ages, everything that helps older eyes is welcome. Most new cars come with halogen headlamps. A decade ago, halogens were exotic and expensive. Now that they are standard equipment, the price has come way down. Many luxury cars are equipped with high intensity discharge, or HID, headlamps. You have probably seen them on the road, they're very bright and have a bluish tint. From behind the wheel, there is no doubt that HID headlamps are the best thing going. However, many people complain about HID ... read more

San Diego Customer Detective Work

One might say the most challenging part of being an automotive service technician at Convoy Auto Repair in San Diego CA is diagnosing a problem before it can be fixed. Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So it's challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it's not something obvious, it's easy for the customer to focus on the fixing and not the diagnosing. Let us introduce you to something we'll call Customer Detective Work – that is helping your San Diego CA technician find clues to what's wrong. We start with the detective basics: What, Where and When. Play along with me. You come in to Convoy Auto Repair and your car is making a funny sound. Do you see where we're going?

How Your Check Engine Light Works

Have you ever had an experience like this in San Diego? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your check engine light started flashing! You fear the worst, but within a block or two, the light stopped flashing, but stayed on. By the next day, the light was off. You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works. Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage. Warning, warning! It flashes the check engine light, to alert you to take immediate action. It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the ... read more

Tire Replacement

You know you need new tires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank. Tire size can be confusing. There's so much on the side of the tire, and it's hard to keep straight. Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing. Let's start with the size number. For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number. The R signifies it's a radial tire. And 16 is the rim ... read more
