I usually buy vehicles that need the timing belt replaced. (Most people trade in or sell at that point for $ reasons). I do most of the work myself because it’s not overly complicated if you follow a manual. People at my office ask me about general car maintenance. When I ask about timing belt changes they always respond with, “Do I need to change that?” or “I have never changed that.”

Sajeev,
Here’s what I got: 2002 Saturn L200 156000 miles bought new. Excellent car no problems whatsoever, maintained precisely. Question about timing chain scuttlebutt. Should I change it preventatively , switch to synthetic oil, or just do not worry about?
