As a result of this friction, the belt and pullet exert more pressure to work properly which ultimately leads to the breakage of the belt.

Too Much of Heat: the timing belt is usually made of a rubber-like material. So if the engine begins to produce a large amount of heat due to any reason, the heat will cause the rubber to melt slowly and thus the belt will decrease its life.
