sjc6765 Posted October 31, 2005 Share Posted October 31, 2005 That is what it sounds like, grruummph,,,,,grruummph,,,,, grruummph very rhythmatic, about 10 seconds apart. Only when the car is cold, after you drive it, no more noise. '93 sc300 with automatic trans. has anybody come across this before? Quote Link to comment Share on other sites More sharing options...
DomLee Posted October 31, 2005 Share Posted October 31, 2005 Have you checked the timing belt? Could just be an old belt...or a tensioner that is somewhat stuck. If so, time to replace these. Quote Link to comment Share on other sites More sharing options...

teelias Posted December 20, 2005 Share Posted December 20, 2005 Does anybody have a step by step for replacing a timing belt? Sounds like a tensioner (already mentioned). Mine was a Power Steering pump bearing. The colder the louder. Once warm, no problems.
