Does the engine head require replacement required due to loose timing belt replacement?
My 2007 Cadillac STS (48K miles with all warranty performed by dealer on schedule)
engine light came on and I took it to the dealer for inquiry. The dealer replaced the
timing belt under warranty but told me that the rear cam shaft bearings were worn but
would not be covered under warranty so I would have to pay for the replacement of the
engine head. Question: wouldn't the rear cam shaft bearing wear be a direct result of
a loose timing belt?
There is no way that they could know that without disassembling the top of the engine. At 48,000 miles on a Cadillac you should have no issues . I think they are trying to stick it to you. What codes were pulled when they checked it?
Double check this but I believe Cadillac's powertrain warranty is 5 years OR 50,000 miles whichever comes first. For this to happen on such a low mileage engine it would most likely be the result of poor maintenance. Tuff is right also, they'd need to disassemble the top end of the engine to make a diagnosis like this. But, Cadillacs aren't what they used to be either!! It wouldn't surprise me to find some kind of engine disaster on any Cadillac, except for the Brougham Series, made after 1981. Definitely get a second opinion. I agree with Tuff, sounds fishy to me.
