How much is a timing belt service

Hello, this vehicle is not equipped with a timing belt. The 3.6L V6 engine has a timing chain, which is installed for the useful life of the engine, and does not require replacement. What is the cause of wanting to replace a "timing belt" for this vehicle? As far as lack of power and transmission concerns, a diagnostic test should be performed by a professional, trained technician with proper equipment and tools as well as workshop manuals for reference. Anything else will be guessing which can be far more costly than a professional inspection. www.repairpal.com/repair-shops
