Replace radiator ASAP. And flush tranny fluid.
The engine coolant reservoir or the overflow bottle.
Mix half water and half coolant in cleaned out milk jug. It may take a few times of mixing to get right amount. Keep doing this until radiator is full. Also, fill overflow res. at this time. Drive a few days and recheck doing this same procedure.
The engine coolant overflow reservoir is to the left side of the engine compartment. Checking levels, adding coolant, and coolant specifications are detailed and illustrated in the Owners Manual - See "Related Questions" below for more

You put it in the overflow jug.
I have an 88 wrangler and my ICM is on the inside of my driver's side fender, under the coolant overflow jug. You have to take the jug out to get to it. Though yours may be different, i know some things were changed on the YJ after "91, like FI. Home this helps someone
In a radiator, the fluids get really hot, when things get hot they expand and then they have to go somewhere, the fluid goes into an overflow.
Remove the jug and wash it out with soap, water and a bottle brush.
Many things can cause the car to overheat. 1. Low coolant caused by leaking hoses, water pump, intake manifold on v6 engine. 2. Bad headgasket on v6 engine causing coolant to overflow out of the reservoir jug. 3. Stuck thermostat. - TechJK ETC. -----------------------------------
Ive had a similar problem with another car of mine. The solution was to run the car with the coolant cap open so the air could be pushed through the lines. Ideally you want to run with an open cap until your pump kicks in. This is the process you need to use when you replace a rad or drain all the lines. Don't be worried if you see coolant gushing out of the overflow. It takes about a minute then the overflow will level off and all the air bubbles will stop.
The head gasket is blown.
