I just had a â€œBâ€? service. The dealer mentioned that it was time to â€œInspect and possibly replace the Timing Chainâ€? next service. I have searched on a few forums and have never found ANY instance of anyone having the timing chain replaced! Are they full of *hit or what? I have 191,000KM on the truck. It is not the serpentine belt but the Chain! Is it time to switch to the other dealer in town for serviceâ€¦.
