2.5 L water pump replacement

Hi,

I'm currently replacing my water pump. I did this once before with someone who knew what they were doing and it seemed pretty easy. Anyway, I remember we removed the fan clutch. I see that it has 4 bolts on it, but they seem to be lock bolts, and when I try and turn them, the tension of the belt is not enough to get them off. HELP, how do I remove my fan clutch?

TIA

First remove the belt. Then hold the fan blade with one hand and turn the bolts with the other!

I don't have power steering. Sorry, I'm a mechanical moron.

Ok, I found a few things that explain it. Thanks.

I also drive a 95 rio grande and you should have power steering...that water pump is super easy to do, just take your time and be sure to seal it good with the rtv.

Depends on what year rig you are working on. My 90 had 2 v belts (before I yanked that sorry excuse for an engine out of its hidey hole) and the alternator belt was in front of the power steering belt. To remove the nuts I just use a screw driver to pry against a nut on the other side and the fan shaft and turn the wrench with the other hand. Go around and do all 4 then just take them off the rest of the way easily. The fan will probably be pretty snug/rusty on the water pump shaft so you might have to smack it around a bit with your palms (NOT hammer). I like to wait til I get the fan off before I remove the belts just for the extra help the tension gives in removing the fan nuts. After the belts are off then the pulley will come off and the rest should be self explanitory.
If you are working on a later one then the only real different is the belt is longer and wraps around everything.

It's a 95 with AC. I have another car to drive, so it's no rush. I did it before with a friend in an afternoon, so I know it's not that bad. But I remember we removed the belt and I think the entire fan blade assembly came off too. Not sure I am looking at the right 4 bolts, they are on the back of the fan clutch itself?

It does NOT have power steering. However, it's the same setup. Box and a pump ... it's got power steering. The pulley is there for it.

I realize a water pump should be an afternoon job .... but I'm an idiot. That throws a whole new dynamic into the situation.

You can also push down on the belt, (hard), with one hand to hold the fan from spinning. Another tip: clean the gasket surface on the engine very carefully so not to leave any old gasket material if you want to avoid leakage! And.... when you install the new gasket, use a very thin bead of RTV, (blue),down the center of both sides of the gasket and around any bolt holes or water passages. Do not use too much RTV as the excess will squish out and clog the heater core. Finally, when you refill with coolant, make sure you purge the air from the system.

Lastly, spend the $$$ for a new pump if you can, the re-builds can be a crap shoot!
