Intermix issues caused by the oil cooler are not that uncommon. If it is the oil cooler, they can pull it and pressure test it to confirm.

Its a good place to start.....if its not that it could be major...unfortunately.

sorry to hear about your problem.
I wonder if I got lucky when I noticed a coolant leak.

What would have to be done to clean the water out of the engine?
Let us know what you find.
Good Luck, I hope the tab isn't to high

The oil cooler had about 1/2 qt in it when removed.

just to update, IT IS NOT RADIATOR, now we will disassemble Engine, will start with head as I was advised.

Use a bore scope to look into the cylinder thru the sparkplug hole for any cracks in the cylinders.

From a 3.6 -- Not sure how easy this would be to see from a boroscope -- but certainly worth the try.

see post #6 for a common type of crack in the head. 1 - 3 side most often. These can be repaired. see post #5
