I have a 97 Honda Civic DX Coupe with CAI/H/Catback and Y8 IM. Timing belt/water pump was changed by a shop about 10,000 KM ago.The Car has 340k and plan on driving it until the engine blows because finances are tight right now. I've noticed since the cold weather has started that there is a really annoying grinding or screaching sound on cold start-ups. The sound comes about 3-4 seconds after the car starts and lasts anywhere from 4-6 seconds. Then goes away with no further issues. I have recently changed the ALT/PS belts and adjusted to proper tension. Could the timing belt be too tight? I've noticed since it was changed that the drivetrain has had a wine to it, especially when starting cold. Any help would be much appreciated before I take it to a shop and pay top dollar for a diagnosis lol!
