wear marks on belt ?

Goldie · 06-08-2008, 09:31 PM

I noticed my belt has some wear that looks like the top of it has been rubbing on something and leaving a brownish mark along the 1/2 closest to the engine. I plan to change it out anyway since it's still the original 8+ year old, 100,000+ mile belt, but would like to know if there's something I should check as to why it might be rubbing somewhere.

Yeah - look for something with a bad bearing, such as the alternator, power steering pump, AC compressor, idler, etc. - i.e., something that has a lot of play in it. My belts on the camper did something similar, and I saw that but it didn't register what I was looking at, and shortly thereafter the water pump failed badly - there was a TON of play in the bearings. Obviously the Duratec's water pump isn't run off the main belt, but everything else is.

Those big wiring harness plugs on the rear valve cover have a REALLY close tolerance there; make sure they aren't saagging and making contact.
