New belt and tensioner belt wobble on pulley
I just replaced my tensioner and belt with the contitech kit (ina tensioner and idler pulley) which finally cured my cold start chirping. I noticed my belt is running straight and good on everything except the new tensioner pulley. I drove 100 miles after and figured it would straighten itself out, but it only has a little bit.
Is this normal even after that much driving and will continue to straighten out or should I take the belt back off and just retry it or can I try and align it while taking a little tension out? Torqued new tensioner to 18ft lbs and marked the bolt and went 90 degrees. Idler was torqued to 30 ft pounds. As I said car drove fine all 100 miles tonight and was definitely not babying it on the last half of trip. Thanks. |

I wouldn’t drive the car in that condition. The clip was short and didn’t get every angle. But you have a problem. It appeared like the belt was walking. It could walk off, and it could take the engine with it. You either got a belt or tensioner problem. I would put the old belt back on to see if it walks, if yes tensioner probably, if no belt problem.
