Clutch Fan are known to fail over time, but I wold not rule out the radiator. The small passages inside the radiator will clog due to age. You did not mention how many miles are on the Jeep or if the Aux fan is kicking on.
Add a comment so I can respond further if you need me to. Thanks.
How many miles are on this vehicle? If you keep running the engine in the temp range or over 200 degrees, your going to blow a head gasket.
If you have never replaced the fan clutch, I would do so. I would also replace the radiator if this has never been done or at least it has not been 100,000 miles or so. In either case, the engine fan that is on the clutch pack activates when heated, and are known to fail. I'll bet the radiator could also use a replacement, if it has not been done as described. Do both at the same time.

I recommend a new radiator vs a used one. Used radiators could also be clogged. While the radiator is out, thermostat replacement and clutch fan might be a great idea also. You say you used a sealant, if you have not done so yet, do not use it unless it is an emergency. Are you still leaking coolant? If so, from where?

I have a 1995 jeep grand cherokee....it's overheating. I've replaced the radiator(used), new water pump. It was leaking coolant and I bought sealant. Do Ineed to replace the radiator with a new one?
Hi,ThankYou getting back with me.your problem is the clutch fan.This will stop the overheating providing no other damage has been done from running at such a tempture, like a blown head gasket.you can check for a blown head gasket with a cooling system pressure tester.If you don't have one,some of your local auto part store's like Autozone rent them.the way there rental works is you pay for it and when you bring it back thay refund your money.I hope this helps,Thank You for using fixya, iluv2fish...Ray

It's a 6 cylinder 4.0 liter. When the a/c is on, it heats up quicker, and gets up around 250/260. I havee not been running the a/c lately. And, when it is that hot, the a/c does not blow very cold.
It has over 280,000 miles on it.
