A high pitched squeal started coming from under the hood, I figured it was a bearing going bad somewhere. Also, the jeep had an off idle hesitation which it has never done before so I really started looking around. I popped the distributor cap and wiggled the distributor shaft to notice a lot of play. I pulled the assembly out and found stress cracks in the housing-

Swapped out distributors and the Jeep is happy again-

Should have new wheelin pics/video this week!

Break it, fix it, wheel it, repeat!

Since sinking the front of the Jeep in that mud pit the e-fan has been kicking on a lot more often. The mechanical fan seems to be freewheeling more than normal, perhaps running the fan under mud put an extra strain on it

Whats that mean? Upgrade time...
ZJ Fan clutch-



Starting the transmission removal...again. More pics when progress is made

Whats your temp gauge reading on a hot summer day down there? I'm right at 210, gets up to about 215 during a stand still then the e-fan kicks on for a moment or two. Eventually Il upgrade radiators but not until this one starts leaking.

Well I have my clutch fan chopped ... My e fan runs all the time and I have the three core, I have a second fan on a switch.

With out the second fan, just sitting in traffic I run under 210. If I start towing or wheeling and I get to 210, I use the second fan and it usually goes back under..

So I maybe run 200-210.

Make sure your transmission fluid is good, I run Mobil 1 now. And a transmission cool will help too. And check your transfur case fluid too. You may be getting heat from somewhere else

I usually take small short pieces of 1/2 x 1/8 inch flat and weld from the nuts that hold the fan to clutch to shaft, making a true solid mechanical fan....at this point my e-fan never ran, especially in models with the expansion tank cooling system...plus .25cents in metal is a heck of a lot cheaper than a new clutch...and you can still remove fan and clutch as normal.....and ive never been a fan of fan clutches...I understand the concept just don't really care about the supposed power loss or increased mpg...so what did you do to the AX-15....

Be carefull while Hugging the Trees...They leave dents on your Jeep....

Shhhhhh I'm not crazy...It's just the voices in my head

Thanks for the tips once again! I was thinking about going with a true mechanical fan or swap another electrical xj fan over when I was first messing with the fan clutch. The ZJ clutch turns at a much higher shaft speed percentage and seems to have the engine running right at 210 again. That is on road, I have yet to wheel with the new fan clutch, I will give your idea a shot if need be.

As for the ax15, I replaced the clutch 5k miles ago with a advance auto perfection kit. It started off pretty good but has become harder and harder to shift and it has a nasty shudder on takeoff. Right off the bat when I pulled the trans one of the mounts for the throwout bearing was broken off hanging there. I'm going back out there to pull the clutch and inspect the friction material and flywheel.

Oh and lastly, I over-tightened the fill plug last month and the housing cracked! I have a new housing, luk clutch, luk flywheel, full metal crown throwout bearing, and arp flywheel bolts to install. Might of ordered HD xj frame stiffeners too, which Id like to weld 2x6 sliders to here shortly
