What are Timing Belts and Timing Chains?

You must have heard advice from your family or friend when you had bought a car to makes sure when the timing belt was done, but did you ever realized what timing belt is? It is essential in a car to about the purpose of the timing belt and also that when it was last changed.

Both of them performs the same function; they need to connect the camshaft and the crankshaft to keep them rotating in a sync. Despite having the similar functionality both are different component. They both have the benefits and disadvantages. They are not visible when you open the bonnet of the car as they are sheltered by the metal or plastic cover to watch them from debris.

The engine is fundamentally split up into two parts; one is the top part and the bottom one. Both the parts of the engine must rotate precisely on time with each other. And this is the accountability of the timing belt or chain to make sure that it happens without any malfunction. If it so happens that the timing goes out of sync only for a couple of degrees the engine will start showing symptoms like:

•    Miss-firing from intake or exhaust

•    Rough running

•    Difficult starting

•    Lack of power

•    Overheating

Timing belts Vs. Timing chains:

Timing belts:

It is made up of rubber which is reinforced with steel wire. It is flexible and there, is no metal contact it eliminates the need for any lubrication. The manufacturer recommends that there should be changing the timing belt between every 60,000 to 100,000 miles, you can ask the manufacturer for the exact recommendation to do so. The water pump can be replaced at the same time as the belt because it has done as much work as the belt.

Timing chain

It is made up of metal and resembles the chain as that of a motorbikes or bicycles. The chain also needs lubrication by engine oil. As a general rule, it only needs to be changed when it is giving specific problems. So the main benefit is that it lasts for long. It also makes louder noise while working.
