I was on the way to take my sister to a fire dept. meeting when I here POP! and temp. guage pegs! I pull over aint hardly got water in it and in the middle of no where! I let it cool down get to the fire deptment and after the meeting Start pouring fuilds in it. Here Splash, splash. Look she is pouring water out the side as fast you put it in there.(pass side) It's at the back of the block, dont look like it is coming from the head unless it is coming from the back. Where is it coming from, Freze plug or what? Help please the poor jeep is sitting an hour away at a fire dept. I need help. Ohh and cant tow home cause aint got the money and the truck is broken down(clutch gone)!

Did you check all of the hoses and the heater control vavle back there?? I am not familiar with the back of the 4.0 head, and don't know if there are freeze plugs back there. HTH!! Later!!

hose are Perfect! Whatever it is, the water is pouring out faster than you can dump it in, with the motor off! It's running straight through! If ain't ever seen someone cry over a car I did tonite because as soon as everythig falls into place for me to start my mods something happens!

Where is the heater control valve? Any pics. I'll try to get some later this week!

Mine is right above the dipstick with the purple vacuum line going into it. I have a Renix with the updated cooling system, so mine is for a 1992, I forgot what year tour XJ is. If this plastic thing broke then it will **** fluid all over the place. I hope that this is what it is!! Later, keep us posted buddy!!

Sounds like a freeze plug to me

Yep sounds like a freeze plug to me as well..depending on which one will depend on how hard it is to repair...

While it is puking at the back on the passenger side and is out of site where it is puking becuase of the hardness but you can see it runnig down the side uder the head!

The freeze plug is behind the flywheel/flexplate and the motor has to come out to get to that plug. Sry alien. Had that happen to me on a 76 Dodge PowerWagon with a 360. It makes you feel helpless because you really are.

This sounds familiar... but is there also a plug on the rear of the head?

Reason i ask.... he OP stated he can see coolant running down the pass side under the head. The coolant would come out the bottom of bellhousing if it's leaking behind it.

I have a spare engine in garage... i'll pull the cover and take a look in the morning.

BlueXJ

Overland you have a chance to snap a pic of that head mounted freeze plug? The reason I ask is I don't remember seeing one there. I have been known (by my wife) to have a faulty memory so I would love to see a pic.

Please look I'm a hour away from my Jeep and ain't got a way to it till this weekend.

Blue, If it was behind the flex plate, it would be pouring out of the bell housing. but I can see it runnig down the block just this side of where the tranny and motor meet!

finneys98xj

Can anyone snap a pic of there motor from the passenger side looking back at where the motor and tran meet and I'll try to map where the fuild is going!

OverlandZJ

Boy you guys are impatient!

Batt's are dead in digi.. figures. But theres a freeze plug dead center in the back of the head. Theres your problem.
