How to Tune Up Your Car.

Cars have hundreds of precise components constantly working, so it's no surprise that the system can get a little bit run down. When you tune your car up you maintain and balance the whole machine, and stop problems before they start. A tune-up isn't everything, but they can save you a lot of money in the long run.

Car's need a tune-up performed from time to time and vary from vehicle to vehicle. Mel's RDS Service center is well equipped with the tools and technical information to carry out a tune-up in a professional manner.

Inspect the spark plugs. If they're platinum, they only need to be changed every fifty thousand miles. Any other types of spark plugs should be replaced more often. Be sure to check the ignition wires as well, because they wear out as well. High quality ignition wires are well worth the cost.

Replace the distributor cap and rotor if equipped every thirty thousand miles to ensure optimum engine performance. If you have a distributorless ignition system just check the ignition coils. Ignition coils do not wear out as quickly, and will not always need repair.

If your car is older than 1978 you may need to change the points and condenser, and then adjust the ignition timing. More modern cars have a computer that automatically adjusts fuel mixture, ignition timing, and idle speed, so there is no need.

Next check and adjust the valves, unless your car has hydraulic valves. Always replace the valve-cover gasket, especially if you see oil leaks from the sides of your engine.

Check the belts. If they are beginning to wear, replace them. The consequences of a failing timing belt can be minor, like a loss of gas economy, or they can be more serious, like a slipping belt causing the engine to misfire. If a belt breaks entirely the damage can be critical.The accessory drive belts need to be checked for cracks and replaced as needed.

Look at the levels of all the fluids under the hood, and refill them if necessary. This is a good moment to change the oil and oil filter, especially if it has been about three thousand miles since the last change.

Replace the air filter. The air filter is a critical component, and extremely easy to change on most vehicles, so it should be changed every 15,000 miles as well.

If you have a manual transmission you should adjust the clutch. Clean the terminals of the battery and the cable ends. If the battery requires distilled water, add the appropriate amount.

Check the PCV (positive crankcase ventilation) valve and replace it if it is worn. A clogged PCV valve can make the car stall or the engine misfire.

This is everything you need to get your car humming like a finely-tuned musical instrument. Work carefully and thoroughly as you tune-up your car, and you will enjoy many hours of happy driving.

Always refer to your manufacturer's hand book for your particular vehicle.
