DRIVE BELT CHANGE - Serpentine belt

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

It was the serpintine belt and no the vehicle did not overheat but it did reach normal temperature faster being it was -2 deg.

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.

I am in need of a diagram showing the routing of the serpentine belt. cannot figure it out. Help!

:D

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.

i got the car with a bad water pump and broke time belt
i replace the pump at belt, the car will start and run with out any misfire. i see water coming out of the muffler. no smoke on idle only water with some dark particles
dont show milky oil or water at the oil sump or dipstik
will run for 45 min with temp gage show normal temp. after 45 to 50 minute will stop and wont. start after 20 min will start and run for 30 min an stop. it will not misfire will runing.
is there any good headgasket repaire that i can tried with out replacing the gaskets or what can i do to fix
or find the problem thx you

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.

Need to find out how to connect fan since there is more than three holes to choose from. need exact diagram of the three belts and sizes, etc.My vehicle is four wheel drive.

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.

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.

Where are the bolts to release the power steering pump belt?

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.

On my 1994 Isuzu Rodeo 3.2ltr v6 Power steering is on bottom, A/C is on top.

Welcome back:

Take a look at the picture I attached. If that is the one you have, it has an automatic tensioner (one belt). Is that correct? If it is, you simply turn the adjuster with a wrench in the opposite directions of the belt and it will release tension.

If that is incorrect, could you upload a picture of yours so I can see what you are working with?

Let me know.

Joe

Here is the pix of the p/s pump.

I'm sorry, but the image you showed me is of a chevy small block. Not isuzu 3.2ltr v6.

So I have this set up(check image) in my 95 rodeo but can’t seem to loosen the tension to take my drive belt off, where are the bolts to loosen it? I am able to take the other two belts off but can’t get the first one.

I believe there is a bolt in the rear that needs to be loosened. I attached a picture of the pump and circled where I believe it to be. I know there are two bolts behind the pulley that mount it on mount, and I believe there is a third on the rear that does the same, but needs loosened to allow the pump to pivot. You have the tensioner loose.

Let me know if this helps..

After putting in some oil, I forgot to place the cap back. It fell into the fan, and broke the cooling fan blades. I didn't notice anything until the battery light on my dash flashed. After I pulled over, I looked under the hood and realized the damage. The broken fan, isn't the problem (or maybe it is?) but the belt going from fan, to crank, to alternator fell off. I put the belt back on, but noticed that the alternator belt was rubbing on the belt going to the a/c compressor. I can't figure out how to adjust the belt to get them from touching.

Hi:
First, check to make sure the belt is properly routed and make sure the tensioner is working properly. This vehicle has an automatic tensioner and can't be manually adjusted.

Go to this site. It starts with engine timing belt diagrams and at the bottom refers to serp belts.

https://www.2carpros.com/diagrams/isuzu/rodeo/1997

This is the Belt Diagram, The it tightens the belt from the adjuster/lock at the bottom of the alternator. I tightened that up, which is when I noticed that the belts were hitting each other. Even with the belt off of the alternator, I can;t find a way to align the belt between the fan pully and the crank below it.

Something has to be out of alignment. Have you checked for any excessive play in the belt driven accessories that could allow the belt to move?

Okay, so I figured it out. The fan pulley bolts to a mount. the mount is made up of a plate and a shaft with bearings so that it can spin. When the fan broke, it wobbled the plate that the pulley bolts to, up the shaft. I tried to press the plate back, but it wouldn't move, so I had to get a new pulley mount.

Glad you found the problem. Honestly, I never would have expected that to bend. It's a rigid piece of steel.

how do you put on a new belt please?

see picture move the tension-er in the direction of arrow and that will relieve tension on belt for removal. The tension-er should be replaced at same time of belt however. it may take a socket or just ratchet end to fit in tension-er to move it. See picture.
