I have a minor issue here and I am wondering what you all think. I replaced the serp. belt last year and maybe have about 3500miles total on it. When I drive normally without getting on it the belt stays in place on the pulleys. However, when engaging in WOT throttle activities the belt tends to walk back a rib towards the timing cover on the crank pulley. I can lift the belt off the idler pulley and place it back where it is supposed to be and then start the engine. This always moves the belt back into line on the crank pulley. I just replaced the harmonic balancer as the old one was starting to wobble some, the belt did the same thing with the old one. I figured with the wobble that was causing the issue. The marks on the tensioner are between point B-max belt length and C-belt replacement. Now I have had the belt off maybe a half a dozen times to do various work on the car since I put it on. I am doubting that the belt is the issue. I think I may have a bad tensioner, it does move freely and has resistance to movement with a wrench but that doesn't necessarily mean anything. My best guess is that a high RPM's when the belt is experiencing high amounts of centrifugal forces that the belt slips off a rib because the tensioner cannot hold it onto the pulleys.
I do not want to replace the belt they are 50 some bucks and the tensioner is 17 years old the belt a year old. So I doubt it is the belt but it is possible, weirder things have happened.
Is there any accurate measurement I could do to the belt off the car to determine if the belt is within spec. and possibly rule that out. I didn't look real hard in my FSM for belt length so if anyone knows...
Your thoughts?
