Why Replacing the Timing Chain on a 1991 GMC Sierra 5.7 is Essential
As an owner of a 1991 GMC Sierra 5.7, I have personally experienced the importance of replacing the timing chain. A timing chain plays a vital role in the engine’s proper functioning, and when it wears out, it can cause major issues and even lead to engine failure.
