Ahhh, I forgot, if I am correct you upgraded your electric windows from manual hence the wiring. The ones from Rock Auto are made/distributed(?) by ACI.

And good to see the seller wasn't out of their mind with a reasonable sale price, like the $23k one on Ebay. If it's as solid as it looks in the pics, that price is not terribly out of line IMO except maybe that it's not 4wd.

I got some window sweeps from www.teamcherokee.com a few years ago. Not cheap, but they were a perfect fit. They have a decent selection of various odds and ends, mostly for Cherokees but a fair amount of crossover items to MJ's. Some items seem to be a really good deal, and others are really expensive despite being available from other vendors. Regardless, a good resource worth checking if something is hard to find. Also, Rock Auto has electric window regulators in stock for both sides right now. I just got my driver side unit after being on back order for several months. They're @$100 for each side. Don, I'm curious since I'll be replacing both of my regulators when things finally warm up, we have a forecast of 5 inches of snow starting tonight!, the units you got and presumably the ones I got are not plug and play?

Hoping you are right. Also, pressure tank and cap are new also.

Didn't say either way. Was exploring all options. Thanks for all the input. Fyi........new heater control valve is metal one.

YXMJ, yeah, I think I'm resolved to getting one and converting to open system, eliminate heater valve etc. It seems that less is more with an open system, more consistent operating temps, easier to maintain/service. Came across a nice write-up in Four Wheeler mag from last summer where they converted an 89 XJ over and was essentially plug and play with new rad dropping right in etc. Being that I've already replaced all the mechanical components in the last couple of months it only makes sense to not only get a new rad as Hornbrod and others have suggested but to convert to an open system also.

Pete, what year and model MJ or XJ would I search for this replacement? Also, my truck has the factory HD cooling and trans cooler. I like the ability to easily do a flush with having the cap. So do you still have the pressure bottle on the passenger side firewall though and the hose off the cap is just a pop-off valve?

Forgot to mention slightly critical item here.........when I changed out tstat I did not drain coolant and just pulled hoses from tstat housing expecting to lose some coolant but when I pulled them off there wasn't much coolant to speak of in the lines.

Pete, other than the obvious advantage are there any disadvantages?

Yes, and just confirmed that again this evening. Put in a new tstat with "jiggle valve" and got it up to temp. Took a solid 15mins before temp got to 230ish, overflow bottle never budged, upper radiator hose cold to the touch. Shut it down and while looking around saw steady dripping at heater valve.

Gonna change out the tstat just to see what happens. Question.......going to use a Fel-pro paper gasket, do you guys recommend RTV with that?

I've seen lots of debate on replacement units and/or going to an open system. I'm generally of the opinion to spend a little more to get quality and do it right.

I'm only the second owner but if I had to guess it's original and just turned 220k yesterday, so I'm realizing it could very well be the rad is finally shot. I've only put 10k on it in the 10yrs I've owned it and it was parked for a few years until last fall. It was the original owner's DD and overall it seemed like it was well taken care of when I bought it. I've never done a flush on it so I plan on doing that, and since a new tstat is inexpensive I plan on replacing it with a OE unit as you suggest or a Motorad fail-safe unit. It will be my 16yr old son's DD soon when I get this and a few other things fixed.

OE closed system

Water pump just replaced, fan clutch, upper rad hose, heater control valve, coolant tank.............

Just recently temp gauge has been slowly creeping past 210 and ends up in the 240 range. At first I thought maybe bad temp sensor because I'd raise the hood and the engine bay was not putting off a ton of heat and there was no hissing or noise from near boil over. Drove it on an extended trip yesterday evening and although it never went in to the red it was just above it and when I got to my destination I raised the hood and the heater valve was spitting a little. Anyhoo, I've also noticed the last few times I raised the hood that the overflow tank level had not budged...........bad tstat?

That is friggin sweet

You da man............many thanks for even looking in to this!

Cool.......I thought that might be the case. Didn't know if maybe you had a water jet......
