When I'm looking at 1990-1993 DeVille's for sale online to compare to my 1992 DeVille, many of them are saying "new timing belt" or "timing belt recently replaced". What and where is the timing belt? Is it another name for Serpentine belt? I replaced the Serp. belt about 1,000 miles ago, currently I have 70,000 on the clock. Is the timing belt something that should be replaced? Does it break often?
Also, how can I find previous threads I've either started or responded to. There is a answer in a previous thread that I started but can't find it and don't want to start another thread to get the answer again.
