Main question: Does anyone know where the air bleeder valve is for the coolant system? I have attached a picture to show how the coolant system and engine looks. In depth description: I replaced the radiator, water pump, and thermostat. When refilling the coolant I cannot get all of the air...

I recently replaced the coolant reservoir on my 2004 KJ 3.7L V6 137K mi. while changing the water pump, T-Stat, rad hoses, drain & fill and air bleed. The old reservoir was heavily gunked-up on both left and right chambers. She's still slowing losing coolant from somewhere, meanwhile, the new...

Heater Core Leak (2005 Jeep Grand Cherokee Limited WK) So... I've got a sweet smell coming into the car whenever the engine becomes warm. Pretty sure I see a filmy residue on the windshield. My guess is that it's a coolant leak. I bought a pressure tester kit and hooked it up to the radiator. I...

Hello all, I have run into an issue with the AC system in my 1999 Cherokee 4.0 Sport. I think I know what the problem is but I am not sure how to proceed. The AC does not blow cold air at all, regardless of how long the engine has been running, outside temp, etc. I have confirmed that the...

Now that its warm again I am overheating. Ive gone through and all looks good but found the fan motor was dying and now dead. It is the 3 pin version with a High and Low speed relay in the block. However all I can find is the 2 pin non towing motor. Its a daily driver and not towing so can I...

I'm about to install a Mishimoto thermostat which is supposed to open at 82C instead of the 90C oem one. Is there something else I need to adjust to pair with this thermostat like electric fan on/off cycle? Its going in a 06 4.7 WK.

Hey there, I have been having a lot of issues with my 98 Cherokee. Bought it a year ago this month and as I was driving it home for the first time she overheated and proceeded to pour a Niagara Falls of coolant from underneath my front end. This struck me as odd because the water pump and...

The tank in my 96 5.2l engine is cracked beyond repair, the replacement tank I was sent has no overflow outlet tube. Is this gong to cause problems, or will the overflow vent out the cap?

Flushed heater core about 6 weeks ago & had heat again. However, now I think I have a bad water pump and/or thermostat. Who can help? Here is the latest. Went to refill the system after replacement with (GATES) upper and lower hoses (low sprung a leak). Left radiator cap off, started engine...

Hey guys - hoping to seek your advice on some of these overheating issues. I have noticed that as Spring is coming into Southern California and the temperature is starting rise my jeep has been running hot. It usually runs about 160* and I noticed when I went to a friends house to pick him up I...

I have a 2003 Jeep Wrangler Sport with the 4.0L 6 cylinder engine, last summer I did a quick fix on a leaking heater hose by trimming the end 2 inches off and reattaching it to the water pump, unfortunatly I replaced the missing antifreeze with regular water, telling myself I'd get to it later -...

I have a Spectra cu1193 that started leaking between the plastic tank and the aluminum core when I removed it to make room for replacing the water pump. It was only about a year and a half old, so I'm not happy about that. I drive across Death Valley in the summer from time to time, and I live...

I've either got a bad water pump, seal, or thermostat housing seal. When I was leaving work, I noticed a large puddle under my Jeep that ran into other parking spots. After the 10 minute drive, I got out and noticed that something smelled warm so I popped the hood only to find that coolant was...

I put a rebuilt 4.0 Renix engine in my XJ back in June. I replaced the water pump, radiator, t-stat, all the hoses, electic fan, fan clutch and expansion tank. It overheated to about 235-240 shortly after. I hooked up the electric fan to a switch and flushed and vacuum filled the system. I...

My nightmare started about two months ago. First my Jeep over heated and I discovered a crack in the radiator. So I patched it with some epoxy and it was good for about a month. Then I (stupidly) let the Jeep idle on a hot day while pumping gas and it over heated again. I got it home only to...

First post for me, Yay!! Alrighty, I replaced my radiator fan in June of last year after an episode of overheating, soon followed by my radiator. Things rolled along until February, when the car overheated again, and we found that the fan had gone out again, and radiator had to be replaced...

Hey guys. I recently had a great little go around with my cooling system after it my 99 XJ Sport overheated. I ended up completely replacing the radiator, t-stat, t-stat housing, electric fan, and some hoses. I don't know if this is a huge problem or not, but my temp fluctuates between 210*...
