I just changed the timing belt and water pump on a 1998 Camry, 4 cylinder. Preventative maintainence.
I used the spring to adjust the belt tension, per the service manual. I checked the spring with a spring scale and ruler per the service manual -- it was OK. The idler pulleys seemed good (smooth- and tight-running, good surface finish).
I now get a mild roar or similar noise around 2000 rpm.
I Googled "roar", "camry", and "timing belt." One hit said that the timing belt will make noise if too loose and if too tight -- that it is very hard to get it just right. True?
Any ideas?
Will it break in? Is a mild roar indicative of a life-limiting condition?
I hate to take this thing apart repeatedly. The lower bolts on the engine mount were a bitch.
Thanks.
