I was driving my 2000 Isuzu Rodeo when my drive belt broke and found that the bearings in a pulley were totally destroyed so I replaced the pulley and drive belt but know my SUV is running poorly. Once I replaced the pulley and drive belt my SUV would not go over 40 miles hour and is idling poorly?

So what it the serpentine belt that you replaced or the timing belt? Did the car overheat when the belt broke? How hot did it get?

This guide will help you replace the belt

So when the belt broke did you check the antifreeze level and how low was it? If it was low it may have gotten hotter then the guage picked up. So you have it cold too in december we where -15 and better for a week here in North Idaho. We are much warmer no with 15 above taking the windchill in factor. I also must ask is it blowing any smoke out the tailpipe like black or blue or any other color? Also how much exhaust it coming out the tail pipe is it good and steady and increase when you have someone throttle it or does it seem to be the same all the time? Get back to me and we go from there.

No black or blue just blowing white smoke do to the cold weather and the antifreeze level is fine. Could there be a timing/belt issue do to the serpintine belt breaking?

Ok do you have a check engine light on or does it come on? If it does then call around and see if any of your local parts stores will do a free scan and get the codes and then clear them and give me the codes.
Now when was the last time that the timing belt was replaced?
When the belt broke it didn't hit anything and maybe diconnect the mass air flow meter or break any wires to it or anything like that did it? Let me know what you find and we will see where we go from here.

Belt keeps bumping off. I have changed out both pulley and an alternator. What else could be causing this?

The power steering pump and generator are rarely the cause of a serpentine belt jumping off the pulleys. Look for a pulley that is turned or tipped in relation to the belt and other pulleys. The most common offender is the spring-loaded tensioner pulley. Next would be one of the idler pulleys. One way to find a turned or tipped pulley is to sight down along various pulleys to see if the side of the belt is peeking out. It should be perfectly inline regardless of where you look. If the belt is off-center by as little as 1/16", it will set up a squeal as it walks across the pulley as it goes around it.

When there's no belt squeal and it's tracking properly over every pulley, that's the time to consider something locking up intermittently which presents a sudden tug on the belt. That will cause the tensioner pulley to bounce and momentarily release tension on the belt. On GM products the generator often does that. On other brands, probably the air conditioning compressor would be the most likely suspect.

Hi there,

if this is diagnosed as a head problem, there is only one thing to do. And that is fix it properly, if you relay on cans of stop leak, you will only delay the inevitable and very possibly do more damage as well.

We do not have a picture of that. Just fit pulley and fan into which holes will line up with fan. See picture for belt diagram.

I have a 1994 Isuzu Rodeo that makes a loud squeeking sound when I start it. I just had the engine rebuilt and the mechanic told me that it needed a new fan belt bracket. I checked with the local junkyards and they didnt exactly know what I was talking about. Is fan belt bracket the correct term? And also if I need a new bracket would I also need a new pulley?

Hi there,

you best go back to the mechanic that did the original job and get him to point out exactly what is required. Pulleys normally don't give any problems.

My alternator belt got thrown off. There are 3 belts and this just happens to be the very back one. How do I go about getting the 2 front ones off to get to where I can replace this one? What tools will I need? Is there a tensioner (I don't see one) or do I have to loosen the power steering pump, etc. To do this job?

Hello, 3hawks1

You must first loosen the pivot the slider bolts of each accessory, here is a diagram I found for you.

https://www.2carpros.com/diagrams/isuzu/rodeo/1994

You can see each pivot and slider (below)

Please let us know happens so it will help others. If this is not right please down vote and enter in a comment of why it is wrong please.

Best, Ken

Welcome to 2CarPros.

Take a look at the attached picture. If that is the set up you have, there is a slide adjustment on the lower right of the pump that moves when removed. Also, there are two mounting bolts behind the pulley that may or may not have to be loosened for the pump to actually move.

Take a look at pic one to confirm I have the right routing diagram. There are a few for this vehicle. If it is correct, loosen the slide bolt and the two mounting bolts behind the pulley. I have attached a picture of the pump so you can see where the two mount bolts are located. In the picture you can see the threaded holes.

If you look through the following link, it shows the different designs. If you see the one that is like your vehicle, let me know and then I know what you are dealing with.

Let me know if you have questions or if this helps.

Joe
