I have oil comeing into my radiator whats worng with it?

If it's indeed oil, you have a blown head gasket or (less likely) intake manifold gasket. It is possible that your vehicle has an oil cooler (like a VW) in which case the cooler seal is leaking. Very common. Or it's not even oil but rather trans fluid - some vehicles have trans cooler integrated in the radiator, and it may be an internal radiator leak.

Check the oil and the transmission fluid. If it's the transmission cooler in the radiator leaking, your transmission fluid will probably be milky colored from water getting into it. If it's oil from a blown head gasket, you'll probably have foamy oil.I have oil comeing into my radiator whats worng with it?
Can be a blown headgasket, cracked cylinder-head or block. If it is an automatic car it can be a leak inside the radiator, the transmission oil gets cooled by the radiator.
Blown head gasket.
Bummer. The oil galleys are seeping into the water jackets thru the head gasket.
blown head gasket and a bad one at that.





Get ready for some repair bills......$$$$$$
If the radiator has an oil cooler built into it, it is probably broken. If this is the case, you will need a new radiator. Good luck
its more likely to be tranny fluid your transmision lines run thru your radiator and possibley your radiator has a eternal leak witch means you need a new radiator,have you checked your tranny fluid?
You most likely have a blown head gasket, allowing oil to leak into the coolant and vice versa.





To fix this, the only way is to replace your head gasket. While the gasket is not an expensive part, replacement will usually bill you 8-10 hours of labor.





You can do this yourself but it requires a significant time commitment and outlay of tools. You basically take the top of the engine off to repalce a head gasket.
