The 2008 Chevy Impala features a timing chain, but it is prone to various engine issues. Problems such as spark plug detachment, loose gaskets needing tightening, and oil leaks can arise. Engine overheating is a critical issue that may lead to fires or explosions. Excessive oil consumption may necessitate more frequent oil changes. It is recommended to replace coolant every 60,000 miles, air filters every 15,000 to 30,000 miles, and spark plugs every 100,000 miles for non-copper plugs or every 30,000 miles for copper ones.
The 2008 Chevy Impala is equipped with a timing chain which is stronger than a belt but may still stretch over time. If you hear a ticking noise coming from the engine, make sure to take your car in for servicing.
