Timing belt and water pump

The timing belt serves a very important part when it comes to making your engine run. The timing belt is the belt that controls the camshafts in your engine and keeps the entire operation running smoothly. It is present in engines with overhead cams, and are essential to keep these cams turning at the right time in order to keep the engine running. Remember that a camshaft is the shaft that opens and loses the intake and exhaust valves in your engine, both letting air in to create combustion, and venting the exhaust that comes from those explosions. A timing belt must be properly calibrated in order to move in time with the motion of the pistons.

When it comes to engines, the two most important terms to remember when talking about timing belts are “interference” engines and “non-interference” engines. Interference engines have a very, very small amount of space between the valves and pistons, while non-interference engines tend to have a lot more room.

Caution A failure in the timing belt will cause the engine to suddenly stop. This means that your car will suddenly stop running and you will not be able to get it started again.
Timing belt should be changed every 60,000 to 75,000 miles, although some belts are designed to last up to 100,000 miles before requiring a change. Regardless though, it is best not to let a belt go more than 80,000 miles or so, even if the recommended change point is a lot higher. Changing your belt early is definitely a lot safer for your engine, and a little money out of pocket can save you a lot of money and a new car in the long run.

Your car’s water pump is an important part of your vehicle. It is the part that is continually pumping coolant to your vehicle’s engine so that it does not overheat. A leak or a defective bearing can cause serious damage to your car’s engine. If you see coolant underneath your vehicle or get high temperature readings, these may be warning signs that your water pump needs replacing or the coolant system needs to be checked.
