General Maintenance Tips For Your Car

A well maintained vehicle will never let down its owner. It will not desert you when you need it most. Here are a few maintenance tips for your car

Check the Engine Oil: To prevent the engine from deterioration, its important that the engine maintains the amount of oil it is programmed to receive. Negligence in doing so will lead to a deteriorating engine performance, meaning you'll get falling mileage.

Make Sure the Lights are working properly: It is important for the lights to be properly focused, for your own and for the oncoming vehicle's safety. Travel on low beam so that it does not obstruct your view instead of helping you along.

Have Suitable Tyre Pressure: The required amount of air pressure needs to be strictly maintained if your car is to get the right mileage and pick-up. Make sure pressure is not to high or you'll shorten the life of your tyres.

Radiator Water: If your engine uses water for cooling, take care to ensure that it is regularly changed.

Some other tips...
Get your vehicle serviced only at authorized service stations
Check the engine oil level once every two weeks. Also check the levels of coolant and water in the radiator and battery.
Always use genuine spare parts.
Avoid accelerating and braking abruptly.
Shut up the engine whenever you expect to wait.
Drive at a moderate speed of 45-55 km/h to maximize fuel efficiency.
Use air-conditioning only when necessary.
Avoid riding on the clutch pedal, and release the clutch pedal fully while driving.
Maintain optimum air pressure in your tyre to improve mileage.

Checking the automatic transmission fluid

Place your car at a level surface and engage the parking brake. Start the engine. Set transmission shifter in "P" (Park) position, and let the engine idle (on some cars this procedure may be different, check the owners' manual for details). Pull the transmission dipstick. Check your owners manual to find where transmission dipstick is located in your car.

Wipe it off with a clean lint free rag. Then insert it back carefully all the way down into its place.

Pull again and check the fluid level. If the engine is cold, it should be within "COLD" marks. If the car was driven and is fully warmed up, the level should be at the upper end of the "HOT" mark. If it's just a little bit lower I wouldn't worry about it. Otherwise I'd top it up. Check the fluid condition also: If it's too black and dirty with burnt smell - your transmission is not going to last. Normally it should be clean and transparent, as in the image. The new fluid comes red. Over the time it becomes brownish. If it is brown, check your owner's manual, may be it's time to change it. Some manufacturers require to change the transmission fluid at 30,000 or 50,000 miles others specify that you never have to change it - check what's your car owner's manual says.

How to top up the transmission fluid:
It's very important to use only specified transmission fluid - check your owners manual or simply visit your local dealer, they alway have proper transmission fluid in stock. Incorrect transmission fluid can even destroy the transmission. Add a small amount of the fluid through the dipstick pipe as shown in the image. Wait for a few minutes - let the fluid to flow down. Recheck the level again. Do not overfill, it also may cause problems with your transmission.

Engine cooling fans

Cooling fans are mechanical devices that removes the hot air and other gases, which is harmful with regards to the safety of the engine unit. These gases and hot air can be discomforting for the people sitting inside the vehicle.

These fans can be categorized in three ways.
1)Fans deliver large amounts of air or gas at low pressure,
2)blowers have high rates of delivery at medium pressure, and
3)compressors deliver at high pressure.

The cooling fan has to be controlled so that it allows the engine to maintain a constant temperature.

Almost all the front-wheel driven cars and vehicles have the electric cooling fans installed in them as their engine is usually mounted transversely. The fans are controlled by a thermostatic switch or by engine computer, and they turn on when the temperature of the coolant goes above a set point. They turn back off when the temperature drops below that point. Usually you find the automatics in more sophisticated cars.

Cars that are rear wheel driven have engines that are usually longitudinally placed and have these engine-driven cooling fans. These fans have a switch that is controlled with the surrounding temperature and is called as a thermostatically controlled viscous clutch. This clutch is positioned at the hub of the fan, in the airflow coming through the radiator. This special viscous clutch is much like the viscous coupling sometimes found in all-wheel drive cars. These types of latest engine cooling fans can be retrieved by placing special orders.

Some designers have applied a semi-analytic and semi empirical formula which is specifically developed for predicting noise radiation from engine cooling fan assemblies. These engine cooling fans significantly reduce the noise that is caused by the engine.
