My minivan started a rattling noise under the hood on Feb. 13.I haven't driven it but twice since and it is still making the noise. I also smelled something like rubber burning at first, but not the second two times that I drove it. I don't see any leaks under my van.
Is this a water pump problem? on 2000 Chevrolet Venture
Check with belt(s) off for any pulley alignment problems and seizing. Tensioner sounds like culprit.
sounds like your belt is out of alignment due to a pulley failing , look under the hood with the engine running the belt should be straight .
also, the belt tensioner is a common failure with these engines. have it checked out soon before it lets you down.
