I hope this is not too long. I really need some help here. 6 months ago i replaced the radiator in my 98 cherokee sport 4.0. I started over heating about 2 months ago. I came hear and did a search. It would quickly over heat to about 260 and drop back down to 200 3 minutes later then spike right back up. I took the 3 most given answers to this problem (water pump, temp sender, and t-stat) and replaced them all. Now i have foamy brown coolant in my radiator ( no doubt from oil) and it leaks from my oil pan, as far as i can tell that is. I am hoping this is not a blown head, as i fear it is. Can anyone shine more light on this? Any and all responses are greatly appreciated, and thanks in advance for any help given.

 

Head or head gasket

 

This is what i was afraid of. Do u think bars stop leak or some equilivent would help?

 

Temporarily yes

 

Thanks for the awesomly quick response and all your help. Looks like i am in the market for a new/rebuit 4.0. Deff. Not getting rid of my jeep, love it WAY too much. Thanks agin man.

 

DONT use bars stop leak i did a few years ago and was a nightmare it clogged every peice of my coolant system

 

Ok, so no bars. Any recomendations for a quick temporary fix?
