my TJ is a bit low on coolant, and im not sure what to fill it up with. there isn't a jeep dealer around where i am, so i can't get the specific fluid from them.

any/all help is appreciated!

Do you have the owner's manual? If not, what year? I think you can download one from Official Jeep Site - 4x4 SUV, Sport Utility Vehicle.

For now until you can figure out what type of coolant is in there, you can add distilled water that can be found by the gallon in your grocery store's water aisle.

My owners manual says a 50-50 mix of ethylene glycol coolant and distilled water, and do not use propylene glycol based coolant, it should say one or the other on the jug

For now, just bring the overflow bottle up to its proper level with a gallon of distilled water.

Dude this is just, as you asked, so you can drive your Jeep to work tomorrow. What you do afterwards is up to you. You can drain all of the coolant out and refill it for a flush, or just drive it as is with the extra distilled water added. You still have enough coolant in the system so adding the distilled (which cools better than coolant anyway) won't harm anything.

Distilled water is always what coolant should be mixed with. I wouldn't have recommended distilled water if it could cause any problems. You don't want to run on pure distilled water but you won't be by just topping your reservoir up with it.

You can get an inexpensive anti-freeze tester from any auto parts store. When you know what coolant to put in after you top off with distilled water, get the full strength stuff and add it when needed until you get the mix right. You just need the anti-freeze to be correct for the winter.

so i just went out and checked it since i know it is cold. the reservoir tank is dry, and i checked the radiator and im sure there is fluid in it, but i can't see it.

yesterday was the first time i saw the jeep. i cant say its leaking/burning coolant because i did not smell it on my 120 mile drive home from the airport, but the needle did get close to the red zone climbing steep grades on the highway.

i have a feeling adding distilled water is not going to be a solution for now, and i will have to search for ethylene glycol coolant.

... I drove from PA to CT up over the mountains for 3 hours at 75 mph and my temp needle never quivered above the 210 degree mark... You my friend need to add some fluid into your cooling system...

Just put some water in the radiator. Distilled / botteld water is best, but any water will work. Or go to the parts store and buy coolent. This isn't difficult. Radiators should be full, oveflow bottle up to the mark. That's it. Nothing else.

I picked up some prestone from Wally world.

It contains water, ethylene glycol, diethylene glycol, sodium 2-ethyl hexanoate, and sodium neodecanoate.

remember not to open the radiator hot, you could loose some skin off your face.

Radiator fluid squirting out

Now that the weather is warming up, after i have been driving for a while, stop, and turn off the engine I can hear hissing under the hood. The overflow tube to the reservoir bounces around and some steam escapes from the radiator cap. What confuses me about this is that the engine never gets above 210 F when driving, and there is a good (as far as I know) water/antifreeze mix in the system and good fluid level. Basically, everything seems normal and in good working order but obviously there is a problem. I replaced the thermostat last summer after a radiator hose blew apart.

Does anyone know what could be causing this?
