Cambelt vs Camchain

The timing chain is an essential component of a car's engine that synchronizes its various parts to work together. Comprised of metal links, it transmits the movements of the crankshaft to the camshaft and grabs onto different gears and wheels. Depending on the car model, the timing chain can be single, double, or triple and is kept taut by a hydraulic tensioner.

The timing chain is similar to the timing belt as both synchronize the movement of parts in the engine. However, the timing belt can also drive the water pump in some car models. In general, both the timing belt and chain are responsible for synchronizing the crankshaft, camshaft, pistons, and valves.

A timing chain offers greater longevity due to its high strength, with no need for replacement under normal circumstances. It requires only a check after reaching 125,000 miles and is resistant to temperature changes. However, its disadvantages include less smooth rotation, which consumes more energy, increased weight leading to higher fuel consumption and noise, difficulty in fitting smaller cylinders, and a higher purchase price. As the timing chain is made of metal links, it needs to be constantly lubricated with engine oil.

More cars are being fitted with timing chains, with BMWs and Mercedes among the most common models. Other cars equipped with a timing chain include all Cadillacs, Alfa Romeo 159, Honda Jazz, Suzuki Swift, Mazda with Skyactiv-G engine.

To check whether a car has a timing belt or chain, it is advisable to ask a mechanic, check the owner's manual or visually inspect the end of the engine by removing a cover. If the timing chain is found to be damaged, it is crucial to seek the assistance of a trusted professional, as replacing it may require disassembling the entire engine.
