PS Pump mount and pivot bolts are 27 N*m.


Wrenching isn't the problem, it's the brains attached to the hands...unfortunately, I'm lacking some of the former so that's why I'm asking you guys!!

You could always get a crows foot attachment for the torque wrench but I just make sure that the nuts for the fan are tight.
Side note...picked up a radiator from the guy that I bought my Weber off of. All is right with the world again. $50 and it's almost brand new, of course had to sit and shoot the bull about jeeps for a little while too. He told me he is going up to Gilbert, MN in June. Check out youtube and there should be some good videos from up there...just search for Gilbert.

Good luck with the reinstall...I did mine when I first bought my Jeep and got it back together with no leaks! One of the few projects I've ever done successfully on the first attempt! LOL That lack of an automatic belt tensioner had me cursing though. ...as did removing the fan clutch!!!

Thanks! Installed, filled, test drove at about 3:30PM. No leaks!!
Still wondering how to torque down the fan clutch to WP studs at 13 ft-lbs....

Good to hear about your cheaper reinvestment
I was wondering if those sawed off open-end wrenches with a ratchet hole were what I needed...LOL!
Just didn't want to put more money into it until I heard a voice(s) of experience.
Thanks!

Glad to here you got it back together! 13 ft/lbs isn't very much so I just use my calibrated wrist.

97' wrangler fan/water pump with studs

I have the version where there are 4 studs/ 1/2" bolts. The fan is pretty wobbly, which I am guessing means water pump bearings are shot. After pulling the coolant container, fan shroud, removing hoses, loosening the belt, and removing the 4 bolts off of the fan/pump assembly, the fan does not slide off. I have tried rapping it to loosen it and soaking it with penetrating oil to no avail.

So for clarity's sake there is not single 36mm nutted assembly attaching the fan to the pump, this is a rfound fan post and 4 studs/bolts version. New water pump has 4 threaded holes where I suspect the studs go once replaced.

So my question is what am I doing wrong? Should I somehow be backing the studs back out of the assemble after removing the bolts to remove the fan?

a wobbly fan may also point to a bad fan clutch.

the water pump shaft has a nub that sticks out to center the fan assembly. give it some gentle taps while turning it to persuade it off.
