Advantages and disadvantages of timing chains and timing belts.
A hot debate between mechanics and car owners is that they say timing chain or timing belt is better.??
What is the function of timing belt and timing chain?
Both of these have an important purpose, coordination between the crankshaft and the valve shaft.
In this video, I present the advantages and disadvantages of the timing belt and the advantages and disadvantages of the timing chain.
Most of the old cars use the timing chain, and of course, some powerful cars also use this system.
The timing belt has advantages and disadvantages that the car manufacturer decides to use in the car, which is the most important reason for reducing engine noise and reducing fuel consumption.
But the main disadvantages of the timing belt is its short life, but in contrast to the timing chain, they have a long life.
The cost of replacing the timing chain is between 1500 and 4000 thousand dollars and it must be done by a mechanic.
The cost of replacing the timing belt is more than 500 to 1000 dollars.
The timing belt replacement time is around 60 to 120 thousand kilometers and the timing chain replacement time is around 400 to 600 thousand kilometers.
In any case, the breaking of the timing belt and timing chain, if the engine of the car is of interference type, will cause the valves to tilt and damage the cylinder head. But this is not the case with non-interfering motors.
When the timing belt is broken, it should never be started again. The test method for timing belt breakage is to put the car in 1st gear and push it.
