Check Engine light came on....
Coolant=Antifreeze. It's the same stuff. It lowers your freezing point and raises your boiling point. That way you don't freeze your engine and you don't boil it when it gets hots. Now, onward....
The easiest thing to do is go buy 50/50 premixed antifreeze. The ratio is ready to be poured right in. The parts store will be able to tell which antifreeze will work best for your Jeep. It more than likely just uses plain jane green antifreeze. That's what I put in mine.
Otherwise you can buy non-diluted antifreeze and add water to make a 50/50 ratio.
A 50/50 ratio is important because too little antifreeze is bad, and so is too much. For instance, a system ratio of 80% is highly ineffecient. That's why I'm suggesting the prediluted stuff. A ratio too low risks having your block freeze up and bust.
If you do add water, DO NOT use regular tap water. Only use DISTILLED WATER. It's cheap, and it's free from impurities, whereas tap water is good to drink, but it bad for your antifreeze system balance due to extra minerals, etc in that water.
You can buy distilled water at any grocery store. It'll be labeled distilled, not drinking, water.
Your coolant should be changed every 2 years unless you have extended life coolant.
Be sure to check for leaks so make sure you're not loosing too much antifreeze. The tank where you pour it is called the reservoir tank, or expansion tank. It's where the coolant goes when it expands when heated.
Be sure not to let animals near the antifreeze. It has a sweet smell to them, but it's deadly. Antifreeze can be recycled. But if you must dispose of it, carry it to your local hazardous waste facility. It only take a small portion of that stuff to taint thousands of gallons of water.
If you have a 4.0 six cylinder especially, be sure to follow these directions. The blocks and heads are iron and they will rust really quick internally with too little antifreeze is used. These are awesome engines often getting 200k miles+.
