I am fast approching 105,000 miles so I know its time to do the timing belt. Currently my car is making a clicking noise at idle that I can only hear with the radio off and the windows up and is inaudable from outside the vehicle. I did some reading and I think it might be the tensioner. I purchased the Timing belt and what I thought was going to be the tensioner from napa but the tensioner came in as just the roller portion. Do you guys think replacing just the roller portion will be enough to eleviate the clicking if the tensioner is even whats causing it? Also the clicking seems to go away when its really hot out if that helps any.
