#1491 of 2589 Jeep Cherokee 1990 overheat! please help
Jun 23, 2005 (1:50 pm)
I noticed that when I turn off the engine the cooling fan goes off too.
Is that suppost to hapen? because I remember that used to keep being on for a while after I turn the engine off.
the problems is when I stop and shut off the engine, I have to put water and antifreeze very often, the cap pops open and all the coolant spills! and the engine it happend only with engine off

Your first post said " when I drive slowly" not when you shut it off. Radiator caps are set to release at a specified pressure. Make sure yours is the correct one for your Jeep and that it releases at the pressure it is supposed to release at (have it tested). If you have too much coolant in your radiator that can cause it to release after you shut it off. This happens because after you shut it off you have no cooling and the heat in the engine heats the coolant and it expands. If you have to much coolant in there then it builds up pressure and it releases. I don't know if your fan is supposed to run after shut off or not. I assume you mean an electric fan. If it used to run but doesn't now then that could be the problem. There should be a relay switch for it. Maybe it's just a loose wire. Does the fan run when the engine is running? Only belt driven fans have clutches and belt driven fan stop when you shut it off.
#1493 of 2589 I've got a question.
Jun 24, 2005 (7:30 pm)
I'm fairly new to the Jeep family. I've always wanted a Jeep, and nearly two years ago I bought my first Jeep. It's a '95 YJ that's mainly a trail rig, and town cruiser when it's clean - which isn't very often! Four months ago I traded my truck for an '01 XJ and last month my wife traded a minivan for an '04 WJ. So needless to say, we've fallen in love with Jeeps. I love that bullet-proof 4.0L motor. In fact, I'm working on swapping one into the 4-banger YJ. So if anyone has an AX-15 sitting around the garage taking up space and you want to get rid of it cheap(hehehehe), let me know.
The question: Why do Jeeps all have a 195* thermostat in them? From the factory, all my Jeeps seem to run hot. I changed the YJ thermostat to a 185* and am much happier with that setup. With it being summer, my XJ runs just above 210* in town. It never goes any higher than that, and my YJ ran the same way before I changed it out. So I'm certain there's no problem as I've seen other Jeeps do the same, including my wife's. What would happen to my XJ if I change that one to a 185* as well?

Thank You for all that info, now even when I drive slowly the temperature is normal, will overheat when I stop and Shut off the engine. I noticed Coolant Leaking by the oil pam, but is not mix with oil, I 'm not sure if leak when driving, because I dont see water marks behind. thank You again

Can't believe no one has any thoughts on this problem.

I believe I've read the higher temps is for emissions reasons. The 4.0L had problems later in life meeting emissions standards (which is why it's a goner now) and I believe the higher temp helped this. The '01's even had some odd intakes/manifolds or something. Anyway, I'm not sure you'll hurt anything by swapping, unless you're required to get e-checked. Then in may not matter anyway as I don't think local e-checks are as strict as the EPA.
#1497 of 2589 Not enough amps in my 4.0L '88
Jun 26, 2005 (9:19 am)
Used to have a 55 Amp alternator, and in rainy nights --wipers, headlights, radio and AC-- I run out of electrical power: wipers stop working, blower works but the AC fan and AC clutch does not. Have to turn everything off, keeping the engine running a while to be able to continue. A few weeks ago I replaced the alternator for a 100 Amp one, but the problem persists. Checked the battery and it is good, and it is being charged ok. Any ideas where should I look next?

This forum is for Cherokee, not Grand Cherokee. It may not matter technically but if you post in a Grand Cherokee forum you may get some input.

Sounds like an overload problem to me, i.e. you are drawing too many amps through part of your system. Look at your circuit diagram(s) to find a thermal protection relay that controls the wipers and A/C components. Either the relay is bad or one of the components is bad (using more current than it should).
