Overheating

Jeep started overheating this morning. Let it cool off for awhile and it sputters when trying to start. It finally started so I brought it to my Buddy's boat shop. It overheated just a tad on the way here less then a mile. Now its sputtering to start again. The water pump isn't leaking at all. Nothing in my oil either. Any ideas?

I just poured more fluid in it. Motor starts knocking when temps gets up then is hard to start then dies. Where do you bleed it at?

Had the same problem. It was a bad lifter.

Still doing it after a new tstat, water pump, and temp sending unit. Flushed the radiator earlier and it was fine. But I have 190 on one side and 90 on the other. Taking the radiator into the shop tomorrow to get tested.

If you have a 4.7/3.7 there is a bleeder screw at the end of the upper radiator hose closest to the engine. I have a 5.7 and i flushed the radiator on mine and didnt need to bleed it.

I had the same problem and it turned out to be the radiator cap. I now carry a couple of extra caps with me all the time.

Went ahead and put a new radiator in her. The flow test showed it to be 50% clogged. Now I've got a new cooling system except for the heater core. Which I bypassed until I'm ready to do it soon
