A timing chain is located inside the engine, and is what connects the top and bottom rotating components in an engine. It has to keep the components spinning precisely at the same time, consistently. Imagine your car’s engine is like a well-choreographed dance. The timing chain is the conductor, making sure everyone (or in this case, every part) moves at the right moment. It’s a strong, durable link in the engine that keeps things in sync, ensuring your car’s performance is smooth and efficient. Unlike some other parts, you don’t need to change the timing chain regularly – but then why are some cars notoriously famous for having to get timing chains replaced prematurely?
A timing belt is similar to a timing chain. It is essentially a very strong cogged (or geared) rubber belt that does the same thing as a timing chain, but does it on the outside of the engine. The engine design is what determines if it is a timing chain or belt type. Japanese engines popularized timing belts; but practically all manufacturers have used timing belts and chains at one time or another. Timing belts are designed with a time or mileage expiration in mind, so it was a moderately easy serviceable part that was designed to be replaced from time to time.
Typically if you had a timing chain, you were worry free for the life of the engine having to deal with anything maintenance related. If your engine had a timing belt, you would typically replace it around 60,000 miles or so. Recently though, some engines have shown to have a real Achilles heel to longevity and/or reliability; even though they have a timing chain.
Is this something that can be prevented? While I’d love to say yes, there are some cars that inevitably will need some type of repair or replacement with their timing chain, despite what you do to try and prolong or maintain it. On the other hand, I have some tips on what you can do to help it more than hurt. I think premature timing chain stretch is something that can be prolonged but can’t be avoided. Sometimes its beyond what you can control- (the type of engine/how it was designed/the components they use/etc).
Next week we’ll dive into why timing chains stretch, along with some engine examples.
