Having problems with your 1991 Isuzu Rodeo ?
The serpentine belt on this rodeo continues to fray. it appears that the belt rides to close to the inside (motor side ) of the water pump and cooling fan pulley. The air conditioner has been replaced and works fine. All pulleys seem to be in alignment. With the air conditioner off and a shorter belt on it does the same thing. Is there something I am missing here. The cooling fan pulley does not seem to have any wear either. It seems to idol and run fine then when at a higher rpm it will shred t
I can probably help you both. Check your powersteering pump. There is a bracket that connects it to the exhaust manifold. My braket broke and the pump adjusted forwards which allowed the belt to get chewed on. I can also help with the routing of the belt. If you have AC and power steering it travels this way, ( I can also give a picture with an email address). Put the belt in through the passenger side by the battery and loop it over the crank pully, now bring it around the water pump so that the inside of the belt is on the crank and the back of the belt is on the water pully, then it goes around the power steering and up to the AC, there is an idler pully between the altenator and the AC compressor, the belt goes under it, then over the altenator, lastly you'll need a 15 MM socket and will have to pull the tensioner to the driverside by pulling to the passenger side and puttin the belt on the outside, Use a long bar and watch that top radiator hose and the fan blades. Its a bit of a pain, but I've had to take my belt on and off so many times I don't have to look at the pictures. Plus the pictures are drawn sideways to the engine. If I'm feeling frisky I'll draw it on paint and post a link for it.
Call carquest and ask if they have a belt diagram section in their belt book... if they do, just go trace it. :)
