OK guys...i have searched and i may of figured this out but i wana make sure. I do not have a blown head gasket first off. OK i was out wheeling yesterday testing out the new locker and gears..and i look down at my gauge...its in the 250 area. i immeaditly cut it off and popped my hood. My overflow container was...well overflowing. I let it cool down to about 210 and then i went on with the trail...never had another hot problem on the trail. Got off the trail and ran great...on the way home (about 4 hours later) my gauge read 240ish and just stayed there. i was only about 2 minutes from my house so i just drove it on home and parked it. I went out of town today and the Jeep is at home. I need to know what parts i need. Im gonna go ahead and get a new thermostat. Also gonna change coolant (50/50). Then when i change it im going to take the cap off and let it stop boiling/bubbling completely. IM not sure if this will fix it but i hope it does. After that what should i do? CHeck the water pump? radiator?...these 318s have some overheating issues.

Thanks for the help
Michael

check the fan clutch. its probably not ther thermostat. but a new mixture should be added. is there water in the oil ? kinda foamy/milkly looking ?



check that then start snowballing it.

already got a new fan clutch...2 months ago. no water in oil.

I had a 93 Mustang GT that ran warm in the summer. I changed the t-stat and put in new fluid and all was much better after that. Change the cap already as it is cheap.

A lot have recommended the Robert Shaw hi flow t-stat as a replacement.

yea thermostat goes in tomorrow...along with coolant flush and new cap. Some people have told me to lose the thermostat altogether and it will free up a lot of problems...good idea?

bad idea, if it overcools, the computer runs in cold start mode, which dumps more fuel until it hits operating temp.....190*.

it is the radiator. Block the the air flow get the Jeep, get it hot and then step on the gas, if you get a noise like it sounds like an school bus (that roar) the clutch fan is ok!!

Money says it is radiator!!
