Still overheating.................

I have a 1998 TJ Wrangler I love it to death and I love to wheel it to my maximum capabilities. Though the previous didnt seem to care as much about as I seem to do. I changed the radiator to an champion aluminum radiator. Next wheeling trip I overheated again, changed my thermostat... Jeep overheated so I replaced the water pump, the Jeep didnt overheat till my last Hollister Hills trip which was yesterday and today. I have no idea now... i am told the stock fan is better than a electric fan on this forum but very hard for me to believe. So my only thoughts would be flush the system and use a different brand coolant with distilled water. Honestly I have no idea.... I am thinking about a ford Taurus electric fan swap other than that I am at lose....

I see you changed the radiator and water pump. Did you check or replace the fan clutch?

I did the paper test but maybe I should invest the 10 dollars and change it myself...

Ok, may sound like a strange question, but does the new aluminum rad have a fan shroud on it??

Really important to not only have a shroud, but have the fan positioned in the shroud the correct depth?

Also the size of the fan versus the hole in the shroud the fan fits into...

Pics???

Changing the clutch is what had solved my issue. I think the part itself was around $40 and took maybe 30 min to swap out. Now I can really here when my fan is engaged. One thing you can try before swapping it out is once you have the jeep warmed up shut the engine off and see if the fan sound freely. If it does that should mean the clutch is bad

Make sure you bleed the air out of the system. Park it on an incline take the radiator cap off. Let it idle with the heat turned on until it warms and the thermostat opens up. Then rev the engine to 2500-3000 sustained RPMS for about 20-30 seconds. Then rev it again, and again and again. Take about 20-30 mins to bleed the Jeep radiator coolant. Turn it off and cap the radiator. Let it cool and check the coolant reservoir. Fill as necessary. After the Jeep is fully cooled down, then do it again for good measure.

Did the new radiator come with a new cap? That cured my overheating problem. When I shut my engine off I could hear it boiling

x2 on the Radiator cap possibility. My 3 year old Stant was crusty with corrosion. Replaced it with a new Stant and the help as well as the bleeding of the radiator.
Cheap fixes are best, and cheap. =D

I had a horrible time tracking down my overheating problem a few months back. After replacing everything in the cooling system i was at a loss. Ended up being the cat. it was slightly clogged. Changed it and have not had an overheating issue since.

Make sure to install only an 18 lb. model radiator cap. And X2 on making sure there is no air trapped in the cooling system which is a common cause of overheating.

Yes the OE belt-driven fan is better/pulls more air than an electric fan does. We wheel in mostly very hot desert conditions here in SOCAL and the factory fan & cooling system is more than up to handling even the hottest of desert conditions. Installing an electric fan would just create a marginal cooling system.

Alright thank you so much I will try bleeding the air out and look into a radiator cap

I just picked up the cap and started talking to the guys there and he said it could be a seeping headgasket leaking exhaust gas creating air pockets into the radiator... Is this a normal problem or pretty rare problem.

I have just finished the revving part and poured a bunch of coolant all over the street

The coolant has a bunch of bubbles in it and it is running above temp. Is it my exhaust gas seeping into my coolant through a gasket like what the guy said at the auto part store

I remember when I blew my head gasket, in another vehicle, I had coolant in my oil.

Mine is seeping exhaust gas into my coolant. Head gasket has many signs to show it is going out. I am thinking since it is just seeping I can retorque the head bolts to maybe stop the seepage

Have you checked your oil to make sure it is clean?

Here are a couple of informative links you might want to check out to determine exhaust gases leaking into the coolant.

Pat Goss: Ask The Expert

Here is a video showing how it is tested. Seems to me any decent shop would be able to help with this.



Worth checking out to absolutely determine the issue.

I would definitely recommend running the test before you run off and try to re-torque the head bolts. It's my understanding that once a head gasket is compressed in the initial install that's it, as in you can't just tighten it back down unless you have a reusable head gasket. If you go in and try to re-torque you may end up doing more harm than good. Could make it leak even more. If it does turn out to be the head gasket just buy a new one and put it in, it's a pretty straight forward job if you are mechanically inclined.
