HELP! Something is wrong with my engine.

your water pump pulley is also connected to the fan and clutch, the smooth pulley should be your idler/ belt tensioner. these will also go bad. n.a.p.a. should have a tensioner in stock.....some where around $30 . if you have anti-freeze right under the water pump. make sure when you get it running . check under the water pump for leaks or a steady drip. this will indcate that the pump is going bad.

The idler/belt tensioner pulley turned, with a little friction, but turned.

If the fan still turns, then its not the fan clutch? How do I tell. Its all turned by the same pulley

If you replace the water pump, make sure you get one that rotates the correct way. It may not be an issue with the newer stuff but with mine, there are two different possible rotations. As was said, it's not too bad a job but you will have to take the radiator out to make room.

Doing it in the cold will suck though.

that is a good point john.. iirc though the newer jeeps are all california emmisions ready.. but back in the day of CJ's and a few early YJ's both california emmisions ready and non cali ready.. this iirc was mainly noticable to the consumer as either sets of V belts or a single serpentine belt. usually the cali ready vehicles in the jeep family had a serpentine belt...

Liz,
If your looking for a warm snow free place to do this.. I have a friend who just opened a garage in Newport who might for a few dollars let you in to use it pm me for more details either way good luck.. if you want another hand or anything let me know id be happy to help out

id stay away from a pep boys reman water pump, better off with a napa reman the one on cleveland ave has on in stock for 40, no point in saving 5-10$ if the pump doesnt last. while ur in there might want to replace the thermostat only 5$ tops. use a little weather strip adhesive to hold the gasket to the pump then on the other side use a little orange silicone. that way the gasket wont try to move while ur installing it and the orange silicone will allow you to slide the pump around to line it up. this doesnt really aid in the sealing of the gasket just helps with proper alignment and guarantee it not to leak, so dont over do it with either the adhesive or silicone just a thin layer will do it. you can do the same for thr thermostat.

I think I might just have my brother tow it back to my grandfathers hanger back in middletown were I was putting the lift on last week. I have to take it back down there anyway to finish my lift modifications, and clean up. You should see the piles of boxes, old parts, and tools! I cant wait to get pics up of that.

I replaced the thermostat 2 months ago when I did my reg maintenance, only because it just went in my car (100K miles). It cant hurt.

I put my new radiator in very tight on wednesday. I gonna take my time and see if I can do it without taking out the radiator.

Me and a friend replaced my water pump on Sat. and it was pretty straight forward. I don't know if there is a difference between XJs and TJs in this area but it went in well. We only removed the fan and tilted the power steering out of the way.

Arent all TJ 4L water pumps reverse acting?

Me thinks me sees a problem. How long was the radiator out? When a Waterpump dries out and its in its end days, it will often fail sortly thereafter. I have seen that before. Again, I would not reccomend doingth ejob with the rad in the way, but, it can be done.

The radiator was out for maybe 2 hours... All I can say is that if it was in its ending days, then I am at least glad it went out in my driveway and not on the trail.

If something jammed up on that water pump pulley (the clutch fan seizing), you may have spun the flange on the water pump shaft. It's just a press fit. That's what happened to me when my fan took out my radiator.

At this point spending 100$ to replace both is a drop in the bucket.

I think I am going to start a thread in the Members forum about adding a CRYING icon.
