Here are some of the standard foreign and domestic automotive maintenance procedures that you should be sure to have done periodically:

Oil Changes: This is one of the most obvious, yet it is also one of the most frequently overlooked. Changing your oil and oil filter every three thousand miles keeps your engine running smoothly. Not changing your oil and oil filter often enough, on the other hand, can be disastrous: Over time, the additives in your engine oil break down, and the oil becomes thick and sludge-like. When this happens, the oil creates resistance on the engine, causing buildup and premature wear. Old engine oil can also cause the rubber seals in your engine to prematurely dry out and crack, creating leaks that can be quite expensive to fix.

There are a lot of quick-lube places that will change your oil quickly and cheaply, which may make you question the need to take your car to a good foreign or domestic automotive maintenance shop. However, it is definitely worth the extra money to make sure an experienced professional services your car. It is not uncommon for quick-lube shops to employ inexperienced teenagers at minimum wage, and horror stories (driving off without oil in the engine, finding months later that the oil plug won’t come out because it was stripped) abound.

Air Filter Replacement: Replacing the air filter is another important precaution that many people forget about. The silly thing is that this is also the easiest thing you’ll have to do on your car. Just as easy, if not easier, as filling the washer fluid on some cars. In fact, this one is so easy that you may not even have to get a foreign or domestic automotive maintenance shop to do it for you. Just make sure you get a high quality replacement filter. If you are not sure where it goes, ask. There will be a couple of clips you’ll have to undo to open the air filter box, but that’s about it.

Your air filter should be replaced once or twice a year. Every six months, you should at least check it. If it looks dirty, replace it. The better airflow your engine gets, the better it will perform, which to you means higher gas mileage and lower maintenance costs over time.

Basic Tune-Up: A tune-up basically involves replacing a bunch of inexpensive, quick-to-wear-out parts, and checking out a bunch of more expensive, slower-to-wear-out parts. This should be done once a year, but again, many people aren’t very good at making sure it gets done regularly.

A basic tune-up involves replacing (or cleaning and re-gapping) your spark plugs, replacing your distributor cap and rotor, and checking and/or replacing your spark plug wires. Other parts that might need to be replaced during a tune-up are your PCV (positive crankcase ventilation valve) and your oxygen sensor. All of these can affect the way your car runs, causing your gas mileage to go down and the carbon monoxide in your exhaust to go up.

Radiator Flush and Coolant Replacement: Your cooling system is a vital system. It prevents your engine from overheating, which can ruin an entire engine in mere minutes. Your cooling system therefore ought to be treated with respect, which means flushing your radiator and replacing the coolant every year or so, preferably at the end of summer or fall, before the cold weather hits.

The reason for flushing your radiator and replacing the coolant is that the Ph balance in antifreeze breaks down after a while, destroying many of its protective properties. Not only will it not cool to as low a temperature, but it will also begin to allow rust to form in your cooling system, which may lead to premature leaks in your radiator.

Be sure your replacement coolant is half water and half antifreeze. The 50/50 mixture has the lowest possible freezing temperature, the highest possible boiling point (meaning your coolant won’t boil on hot days), and will protect against corrosion inside the system.

Automatic Transmission Fluid and Filter Replacement: Many people don’t realize that their automatic transmission contains fluid and a filter that need to be replaced periodically, just like an engine. Unfortunately, neglecting this maintenance repair can result in parts in the transmission going out more quickly than they should, requiring you to overhaul or replace your transmission, which is a costly venture, to say the least.

The fluid and filter in your automatic transmission should typically be replaced about every 25,000 miles, which is less than a year’s worth of driving for most cars. The oil in a standard transmission doesn’t need to be replaced as frequently. Replacement about once every couple of years, unless you happen to do a lot of hard driving, such as towing.

Keeping up on these five preventative maintenance repairs will ensure that you maximize the life of your car. A good foreign or domestic automotive maintenance shop can help you keep track of the required maintenance, making sure that you don’t miss anything important.

When you find yourself receiving angry glances from people while you’re driving in town, take it as a telltale sign that you are indeed having some muffler trouble. The noise your car is making is not a part of your imagination. Actually, the faster you accept the truth that you need to have a muffler repair, the sooner you could get the problem fixed. If you continue to procrastinate it, you?ll end up in an auto shop with a considerable bill for the muffler repair service.

Before anything else, what are the warnings that you are in need of a muffler repair? Your car may be making a lot of noises but not every squeak, squeal, and screech calls out for a muffler repair. How can you be sure that the sound means muffler trouble?

Once you?ve heard a rumble coming from your sedan, read this as a low-pitched rhythmic sound, then chances are you have a malfunctioning muffler, converter, or exhaust pipe. If what you?re hearing is a clunk, which is a random thumping sound, then what you have is a loose muffler or exhaust pipe. Like what my math teacher told me, identifying the problem is half of the solution. After knowing just what it is that?s making your car so noisy, then we can begin the muffler repair.

The problem is a loose muffler or exhaust pipe.

Don?t even think about muffler repair on a still hot muffler. When you just finish driving the car, leave it for around an hour. That will be enough time for the engine and all the other auto parts to cool down. After drinking a glass of iced tea and enjoying a little conversation with your friend over the phone, you and your car are ready for some muffler repair.

Lift up the car and carefully secure it on jackstands so that you can go underneath and start some damage control. The exhaust pipe is likely to be found about two feet behind the engine pointing toward the rear of the car. If you are looking at the right place, then you will be able to see a thin metal shield right in the middle of the exhaust pipe and the car floor. If you still can?t find it, it is approximately under the car seats. With all those clues, I?m sure you already have an idea where it is.

Now that you have the metal shield in your line of vision, do everything possible to make it rattle. Poke, prod, push, pull, by all means, do what you can so that you will be able to hear the same thumping sound your car is making when you drive. You may be asking yourself why you have to make it rattle. Well, you want to be 100% sure that all you have is a loose muffler or exhaust pipe. Otherwise, the solution I have here will not do you any good.

If there is no rattling sound even after you did your best to produce the same sound, don?t smile yet. Cover all your bases. Start the car engine. I want to make the next statement as clear as possible. Do not go back underneath the car while the engine is running unless you like the idea of pain inflicted in your own skin. Rather than going under the car, simply lean your head down and listen attentively to distinguish where the clunking sound is coming from.

If the source of the noise is the heat shield, all you have to do now is to tighten it up. Turn off the engine first then go underneath the car. With your good old screwdriver, tighten all the bolts connected to the heat shield and I mean, every single bolt. While you are already down there, check if the heat shield has been twisted or curved. You can fix a bent heat shield through a pair of pliers or a screwdriver. Pull the heat shield away from the spot where it makes contact with the exhaust pipe.

That?s it. Just by tightening the bolts, you can avoid the hassle and the cost of going to a car care center for a muffler repair. You can now drive in style and in silence.
