I drive a 2001 mitsubishi montero limited 3.5 liter.I was driving and my timing belt came off then the brake, battery and the a/t temp(automatic transmission) light came on . I did some more search the auto tension was broken . I buy a new one and a new timing belt I installed it every thing is working fine now, But I look in my radiator and their was oil in it what could be the problem

 

, check if you have bent valves, if your timng came loose oil in your radiator can be the least of your problems

 

Come on JP. If that was the case then the car would run like *****. Not to mention it would be burning a crap load of oil.

I dont really know what would cause that.... there have been a couple other members on here with that problem. Maybe use the search function and type in oil in radiator, and see what you get.

 

Sounds like a possible bad head gasket.

 

yea sounds like a head gasket to me

 

Check under the oil cap for some white goop

 

Run the car w/ the radiator cap off and see if you have a lot of air bubles coming out, thats kind of and old school way to tell if you have a bad h/g.

 

True that.
