Replace Only the Timing Belt or the Three-Piece Set?

[SavannahFitz]

Replacing the timing belt requires changing the three-piece set: 1. It is necessary because some engine water pumps are driven by the same timing belt. If the belt is worn out or corroded, it must be replaced. If the water pump is independently driven, the timing belt does not need to be replaced unless it has reached its replacement cycle. 2. The timing belt is a consumable item, and if it breaks, the camshaft will not operate in sync with the timing, which can cause severe damage due to valve and piston collision. Therefore, the timing belt must be replaced according to the manufacturer's specified mileage or time. 3. During the operation of a car engine, the four processes of intake, compression, combustion, and exhaust continuously occur in the cylinder. Each step must be synchronized with the movement and position of the piston to ensure proper coordination between intake, exhaust, and piston movement. The timing belt acts as a 'bridge' in the engine, transmitting power from the crankshaft to the corresponding components.
