Overheating

I pulled in today after 5 miles to the kids school and back, and I could hear bubbling. Got out and I was pouring coolant all over the driveway. I didn't notice that I was over heating. I let it cool, then drove it to an auto parts store. I bought a thermostat and gasket, put it in and then had someone flush my coolant. 5 miles home and had to turn on heat to keep from overheating. What should I do next?

Are all of the hoses hot? You could have a blockage somewhere. When was the water pump last replaced? If you need one, I have a brand new one that unfortunately I can't use.

The hoses are hot. I noticed when I was changing the thermo. I'm doing all of my troubleshooting on the fly through this site. If you guys say water pump, I'll give it a shot . What about bad radiator? Do I just keep making changes building up to the radiator? I'll get a new cap and water pump next I guess. Is water pump difficult install?

It's an easy install. Should take you about 2 hours even if you are clueless (I was). Do you have a Haynes manual?

I had the same exact problem, but only happens to me in the summer months, changed the cap and worked like a charm! So don't go out and spend 50 bucks on a water pump, start with the cap

What condition is the radiator cap in? If it isn't holding pressure the boiling point of the coolant will lower. Its a cheap and easy part to replace before you start spending more money on bigger things. Also if it was the water pump failing you shouldnt have hot air blowing through the heater vents.

Getting cap and pump now. I opened cap and watched coolant while cool. It didn't seem to be flowing. I'm doing cap first. Then maybe pump tomorrow.

Start small with the cap, coolant isn't always flowing. I had the same exact problem, and it turned out to be the cap.. Start small them work your way from there...you might be replacing a perfectly good pump..

Well the cap was not the issue. I changed it and within 15 min of driving it was starting to go in to red again. So today I took the kids to school and decided to go to napa and get the radiator as well. It was $160 not bad considering I was getting it by 2:30. I just figured if I was ripping the whole thing apart to do the pump I might as well do both. I put on the opening day redsox game in the garage and made a day out of it. I must say it was the most gratifying day I've had in a while. I had never ripped in to a engine like that before. I have done lots of cosmetic things to the jeep, but never the engine. It wasn't as challenging as I thought it would be to get the pump off. Made a sandwich, then started putting it back together. After I got the pump on I picked up the radiator, which was in by 1:30. Threw that in, then added fluid. Saw no signs of leakage then started it up. Started squeezing the hose to get out air bubbles. After about 10 min I put the cap on and took it for a ride. Drove it hard for about 20 min and never went over 210! I must say reading all of these forums and posts gave me the info I needed to feel confident to do this, Thanks to all on this site.

It shouldn't flow when cool. That's what the thermostat is for, it opens up when the water gets to a certain temperature to let the water circulate.

What condition was the pump in? I am just asking as someone else might have the same problem, and hearing that they have to replace thermostat, rad and pump along with coolant to fix it, isn't what they would want to hear. So just narrowing it down, I'm betting pump.
