Hey so I don't get it...you pulled out the therm, put the housing back, filled the coolant from the overflow tank, but then how did you put the thermostat back without letting air in again?? Thanks
I didn't see anyone mention that you can also remove the coolant temp sensor from the top of the block in the rear of the valve cover. Fill it from the pressure bottle without the engine running first until it comes out the hole where the sensor goes. Then put the sensor back in and run the engine with the cap off the pressure bottle until it warms up. This can take about four warm up cycles to fill the system with 12.5 quarts of 50/50 coolant.
I have changed the thermostat, water pump, reservoir bottle, reservoir cap, radiator and the damn thing is still over heating. Ive bleed the system also with the cap off. IDK what else to do. Was thinking about taking off the freeze caps from the block and completely flushing out the system. Someone told me that they make some stuff that u add to the system and run it until hot and then drain and it gets all the crap out and unplugs it. It seems to run find for the first 15 minutes at about 180-190 then jumps to 210 and starts to over heat. Any Advice? frustrated...
I have heard a lot of people saying their mechanical fan goes out. I have been looking at replacing mine with a more heavy duty one. I have also seen a lot of people talk about their fan clutch going out. Just a couple things
Well hopefully they figure it out sometime in the last 8 years. :}

Well I got done putting my Jeep back together. Changed the water pump, timing chain, headgasket ect ect. Well after messing with it for an hour and still having it over heat and not being able to bleed it I decided &uck it. So I pulled out the termostat, put the housing back and filled it up that way. I can't beleive I messed with that stupid thing trying to bleed it for over an hour. 15 minutes and it was completely bled and not overheating at all. It actually runs about 190. From now on thats the only way I am going to fill it up when I completely drain the system. So much easier.
do you hqve to use the bleeder valve or can i do ot with out that

Okay... dont want to leave you hanging as a newbie...
do the following
After you have your water/antifreeze mix topped off... (obviously making sure your petcock is completely closed too)
Leave the radiator cap off.
Park your XJ preferably on a slight incline (front of jeep facing up the hill) as air will rise to highest point
keep it running at idle
just watch for bubbles
When they quit coming up... (making sure the coolant is topped off dont let it run low)
maybe gently rock the jeep side to side... to help remaining trapped air find its way to the top.
Once you have it where you've done all that and after a minute or two and you see NO more new bubbles... you're probably good to go.
Put the rad cap back on and shut it off.
Also make sure that you keep your overflow tank at the right full mark during and after this process.

Bought one of these spill-free coolant funnels years ago. Never used it because not needed with correct coolant filling techniques.
It's self bleeding system setup.
Also, it really helps if you use a thermostat that has a small bleeder in it. Or you can drill a 1/8" hole near the top to help get air out. For the older jeeps with the temp sensor in the back of the head, you can also loosen that to let air out.

do you know what years had the one in the back of the head?
