When should the timing chain of EA888 be replaced?
2 Answers
For models equipped with EA888 engines before July 2012, the timing chain must be replaced after 60,000 kilometers. The relevant explanations are as follows: 1. Reason: After 60,000 kilometers, the engine's tensioner may become loose, leading to the risk of timing chain misalignment or even cylinder and valve damage. If there are symptoms such as oil loss, difficulty in starting, or sudden engine shutdown while driving, immediate replacement is necessary. 2. Precautions: During replacement, the tensioner 06H should be replaced with 06K, the timing chain should be replaced with a threaded type, and all four guides should be replaced. It is recommended to replace the entire set, including the tensioner, timing chain, balance shaft chain, plastic guides, and the lower side cover.
I've driven a car with the EA888 engine for several years and found that the timing chain replacement really depends on the specific situation. Generally speaking, this chain doesn't need to be replaced as frequently as a belt because it's more durable, but early models of the EA888 were prone to chain elongation issues. Based on my experience, it's time for a thorough inspection around 150,000 kilometers. If you hear clicking noises during startup or the engine light comes on, you should get it repaired immediately. If chain failure isn't addressed promptly, it can cause engine interference, which would be expensive to fix, with repair costs starting at several thousand yuan. I recommend having technicians check chain tension with diagnostic tools during regular maintenance for early prevention. Remember, safety first—never delay inspections, as chain issues affect the entire engine operation.
