1. Maintaining the battery life of a car:
Manufacturers usually say that the battery is maintenance free but one should never believe it. The battery should be regularly checked to enhance its life and prevent the chances of being stranded with a dead battery.
The battery should be kept clean as the current would get drained by a dirty case. The battery posts or terminals should also be cleaned and care should be taken to see if the case has any damages such as cracks, bulges etc. as it requires replacement in such cases.
2. The filers in the car engine:
There are many filters such as those of oil, fuel, transmission, and air which are essential for preserving the engine, so it is needed to change them as per a definite schedule.
There is about a quarter of dirt oil om the oil filter, so it should be changed after every oil change or every other oil change.
As a part of the tune-up, it is necessary to check and change the air filter whenever it is dirty or after every 2 months. These filters can be blown with compressed air to clean them and enhance their longevity.
If a fuel filter is clogged, it results in poor engine performance, so, no matter how much the makers and deals tell not to change them, it is better to change them once every year.
Initially, the transmission fluid should be changed after 8000km and then after every 40000 km or two years after that.
3.Changing the spark plugs:
Certain cars are equipped with lifelong plugs which last for about 160,999km but if this is not the case with your car, the switch should be done after 48000km. the spark plug wires should also be changed which have a life period of 80,0000km. If the wires are damaged, they can spoil even high-tech new spark plugs.
4.The PCV(positive crankcase ventilation) valve:
The PCV valve is a device responsible for controlling the emission in old cars. It recirculates the partly burnt gases from the crankcase of the engine to the combustion chamber. In order to ensure that the engine functions properly, this valve has to be changed after every 48,000 km. Also, it prevents the formation of harmful sludge and corrosion. The correct PCV valve should be used or else, the engine will be damaged.
5. Lubricating the lug nuts:
This is needed in order to avoid freezing the studs because of corrosion. It is an expensive job to get them repaired. So it is better to use the anti-seize lubricant after cleaning the stud threads with a wire brush. Besides the lug nuts, this will also prevent the spark plugs from seizing, thus they won’t loose while driving.
6.The timing belt:
If a timing belt fails, it can cause you a damage worth thousands of dollars. So it is a good practice to get them changed after 50,000 miles or as per the owner’s manual.
7.Testing the drive-belt tension:
This should be done every month. Very tight belts can wear out the bearings in the accessory parts such as the AC compressor, water pump, and power-steering pump. If the belts are very loose, they will wear out easily, leading to premature failure.
It should be tested before starting the car so that any kind of injury can be avoided because of a hot belt or moving engine part. The tension can be checked by pressing the belt’s longest exposed run’s center by placing a ruler next to it. If the depression in the belt is nor more or less than 0.5-1 inch, then it is good, otherwise, the belt tension can be adjusted according to the car’s service manual.
Besides this, it is important to look out for damage in the belt such as glazing because of oil leakage, fraying or cracks.
