serpentine belt problems

Postby txs » Wed Dec 16, 2009 6:48 pm

Ok, I got the non air belt and tried putting it on, while it's a good bit shorter than the air version belt it's still that new railroad, Norfolk and Way. you sure there's not an extra idler I need to do the switch?

The nonAC belt is routed a different way. You probly don't have a diagram eh? Maybe someone can post one for ya, I've seen it online before.

Bill, I figured out the routing but is it ok to run the grooved part of the belt over the flat pulley of the tensioner.

No. It goes like this:

Crankshaft UP to FAN
FAN to ALTERNATOR
ALTERNATOR to WATER PUMP
WATER PUMP to IDLER
IDLER to CRANKSHAFT

The way you are doing it will make the belt come off. Ask me how I know.... :yuck:

This came off of my truck, cant be wrong.

That is the routing I used but the ribs are on the tensioner pulley, ain't no way to get it on the flat side of the belt, definitly don't want to screw up the new belt, freaking thing was 50+ $

Sorry, my bad. I did it some other way and it popped off.

Tom, it won't hurt it any. Lots of belts run like that. If you're worried, you can get a grooved pulley.

Just enough power to break everything behind the crankshaft.

Looks to me like standard setup (non-A/C) runs with grooves on the tensioner pulley.
