Does the Corolla Need to Replace the Timing Belt?

[SavannahMarie]

The timing belt of the Corolla should generally be replaced when the vehicle has traveled between 60,000 to 100,000 kilometers. The specific replacement interval should be based on the instructions in the vehicle's maintenance manual. Function of the Timing Belt: The timing belt serves as a connecting link between the preceding and the following. The upper part connects to the timing wheel of the engine cylinder head, and the lower part connects to the crankshaft timing wheel. The timing wheel is connected to the camshaft, which has cams. The contact point is the small rocker arm, which generates pressure through the power transmitted by the timing belt, playing a role in lifting. The lifting of the intake valve allows atomized gasoline to enter the cylinder, while the lifting of the exhaust valve allows exhaust gases to exit the cylinder. History of the Timing Belt: The timing belt first appeared in the 1960s and was used in most 4-cylinder vehicles, with increasing application in V6 engines. Initially, timing belts were used in overhead camshaft engines. Compared to traditional timing chains, timing belts are more prone to damage.
