When to replace the fan belt?

[HUGHP]

Our 04 Sightseer with the V10 is at the dealer for other issues but wonder if it would bee wise to have them replace the serpintine belt. Don't think this is a repair I could do stuck out in the boonies. Just turned 35,000 miles.

We use a conservative 10yrs or 50,000 miles and have never had a failure. Manufactures say 100k but.....

The newer EPDM rubber that belts and hoses are made of now do not oxidize nearly as bad as the older ones in the 70s and 80s. 10yrs is no problem.

If it will help you sleep better on the road, go for it. Especially if it can be included in the shop hours currently being done. Eather way, keep the old one or buy a new one for a spare. BTDT, had it swapped out when I had to have an alternator replaced in Whitehorse, YK.

Hugh, for whatever it worth, we have 68,000 miles on our coach still has the original belt. I asked the service tech to check it when I had it it for a generator fuel line replacement and he said it still looked in good shape.

belts like sparkplugs MFG says 100,000 miles for each; seems like a lot, seems like a personal thing; whatever your confortable with. just keep an eye for cracks and fraying on the belt; if you got an engine miss its time to change the plugs.

The official answer at least according to me is when you see signs of cracking, slipping or hear squeals.

I would go ahead and replace the belt, bag it up and keep the old belt on the coach for emergencies. I carry a spare belt and and a spare fuel filter for the truck diesel in the tool box.
