You will need to have repaired/replaced. cooling system will need to be flushed and it is best to replace all hoses as the oil will soften the rubber and cause to swell and pop. be sure to have overflow tank flushed out as well. was this the trans cooler? will need to change tranny fluid also.or engine oil which ever.

Where is the oil cooler located? Does it have a water jacket?


if you are referring to the oil cooler for an automatic transmission, then it will mostly be in the radiator bottom/side tank and uses coolant to cool the oil. They have a habit of cracking/leaking and putting red oil in the radiator or allowing coolant into the transmission. The fix for this is costly flushing of the engine system and transmission and a new radiator. I would consider an air cooled oil cooler as they are more efficient and not prone to coolant problems.. They are generally cheaper than a radiator as the inlet/out let pipes can be blocked off

Oil in radiator


Hi
you didn't say what the car is or any other information.
I can tell you generally, oil in radiator means: engine oil cooler, transmission oil cooler, cracked engine head or cracked engine block. about the heating problem, the heater matrix is blocked with oil, the coolant in not going trough. you need to flash the cooling system including the heater matrix.
good luck

You have oil leaking into the antifreeze and if this is happening you also have antifreeze leaking into engine oil could be head gasket or intake manifold gasket or cracked engine block Has the engine over heated resently at any rate antifreeze in the oil is vary bad and will distroy the engines oil ability to lubericate the engine parts

Leaking oil and overheating after I hit a raccoon. the radiator and oil filter is a little banged up but appears fine other than that. But behind the radiator there is oil everywhere.


sounds like a cracked cooler. Is the coolant leaking out too? there may be a independant oil cooler that was infront of the rad, and is now damaged. Shampoo the engine compartment with a good degreaser, and run the motor for ten minutes if it will drive without overheating, find the source of the leak, some residue oil may still be left, so check well.

Here is the way to find out pull your spark plug put out and bring each cylinder tdc and put 50 psi air in that cylinder remove radiator cap and check for bubbles do this to all cylinders,if no bubbles I would be checking to see if that engine has a oil cooler that could leak oil into your coolant,some mercededs had oil cooler,
