Need Urgent Help - Pulley came off while driving

Back Story: I recently was stuck during the huge snow/ice storm that hit the Midwest a few weeks ago. After I was pulled out of the ditch, my belt squealed very loud. I notice that it was completely on one of the pulleys (that one that is no longer on). So I loosened the tensioner pulley (I believe - the one right below the one that is no longer there) and was able to slide the belt back on an d I had no problems, until today...

What happened today: I was driving home from Iowa until I started to smell burnt rubber, I first assumed it was my belt since I have had recent problems with it. I was only a mile or two from home - so I decided to slow down and try to make it home. Before I turned to go into town I heard a loud crack - it sounded like the belt snapped in half - I lost power steering. I made it to my garage and at this point there was a lot of steam coming from under the hood. Anti-freeze/coolant was leaking out of somewhere but I wasn't sure where. Not much came out - less than a soup can worth. I then realized that the pulley was lying on one of my radiator fan blades and the belt wasn't broke and was all tangled up. I also noticed that the pulley I previously tightened up was not straight...

I took lots of pictures because I'm a firm believer that they help tremendously. Hopefully someone can help me. I need my Jeep to be running tomorrow evening...

This is how it was when I first opened the hood

As you can tell the tensioner pulley (I think that's what it is) is bent

This is a look inside of the (broken?)pulley's socket. I can feel something in there like a metal o-ring sort of thing, also the whole this moves very easily. By the whole thing I mean the metal inside ring that is surrounded by the black bumpy plastic. I also got a piece of metal out of the inside of it, it was really small like a shaving.



Thanks to anyone that has any advice or input. I will take more pictures if needed or try to explain anything else more if you would like.


Thanks!

Get a new power steering pump you should be good- Rockauto's a good place to start they usually have a 5% coupon floating around. Shouldn't be do bad to do.


Looks like the shaft failed, did it take anything else out?

I didn't notice anything else that went out because my heater hasn't worked for a couple weeks and I don't have AC in the Jeep. What about the tensioner pulley that is bent then?

Agree with tsc in that its your PS pump. Once thats replaced along with a new belt I'd inspect everything on your cooling system. The failure of your PS pump will not cause you to leak antifreeze but parts flying could. So check everything over good.

And replace the tensioner if its bent.

Ok, but what would cause the power steering pump to fail? Also since I need it fixed tomorrow - I would have to get a autozone power steering pump... The belt seems fine, a couple minor tears, but noting cracked or worn through.

Also is that what that pulley is called? The belt tensioner?

looking at autozone it looks like the pulley is sold separately- you might want to get a new pulley unless you have a way to remove the old one from the shaft.


It looks like the whatever retails the shaft on the power steering pump failed and allowed the shaft to pop out= not sure you can repair that.


This might help- but I didn't watch all of it




Pretty dry. but it gets to the point

I think that the belt might have jumped off the power steering pulley again and it caused it to wobble out. Does that sound possible? Also I hope they're open on mlk Jr day.

No, what happened is your power steering pump blew up and that's why the drive pulley left. The anti-freeze is very likely from holes in the radiator tubes that were cut by the fan blade when some of them got pushed forward.

This repair will likely involve a new steering gear at some point due to metal bits from the pump not making the one you have very happy and if you don't get all of them out of the system, they will take out your new pump.

You will likely need a new radiator, new serpentine belt, new steering gear at some point, power steering fluid, coolant, and a place to get all this done.

The tensioner pulley has two points of tightness you need to address. One is the long screw that moves it up and down in the slot and you should not turn that until you loosen the bolt in the front of the pulley. Once you make the adjustment, then you tighten that bolt back up to keep the pulley from wobbling and also to lock it in place in the slot.

If you are unsure it is a good part, add one of those to the list of things you need.

Also, be cautious of your belt tension. With that style of adjuster, you can easily get the belt too tight which will take out the new pump, idler, water pump, or anything with a bearing in it that it turned by the crank pulley.

What exactly is a steering gear?

My radiator looks fine, no cuts though. I couldn't even bend the metal fans blades to touch the radiator. I'll look more for some leaks.

My coolant level looks fine, maybe a little low. I have a garage with a good supply of tools, so that shouldn't be a problem.

How much power steering fluid would my Jeep hold? Should I just bleed my lines, or completely flush them with new fluid?

On my list, I have a power steering pump and serpentine belt, currently.

Mrblaine hit on the big piece you probably need a new radiator too.

The belt squeal was probably a seized pulley.


Steering gear box attaches to the other end of the power steering lines- it attaches to the frame and the pitman arm.


The metal shavings from the failed box will take out lower part.

Is there a torque spec for the bolts on the pulley?

Unless I'm missing something you left out about another possible leak for the coolant, there is no reason to see or smell coolant after an incident like this unless the incident damaged the radiator, a hose, or the coolant reservoir.

I'm not there and can't see it, so it's possible that I'm wrong. We'll know for sure when you get it fired up and back up to operating temp.

In regards to the coolant. From the pics, I dont see where the fan hit the radiator, which would be pretty obvious on the cooling fins... My guess is a hose.
