2007 cl500 w216: Oil in radiator:
Can somebody direct me. I think I have transmission oil in my radiator. It is creamy yellow. This happened after the car fell off the jack on the driver side. Insurance are looking for a link between the incident and transmission oil in the radiator. All I know is that I checked the water before the incident and it was fine. I then drove the car after the incident and the next morning noticed the oil in the radiator.

Can anybody help me. What could the link be if it is related. If they find it is not related I will obviously have to pay for the damage. Is there a technical reason to exclude the oil in water because of the fall off the jack?

Oil in the coolant (radiator) is not a common issue on the M273, at least not that I've heard. A huge number of things or very few could have occurred due to your call falling off the jack, it really depends on the damage the car sustained.

It would be good to determine what oil is in your coolant, be it engine oil, transmission fluid, steering fluid, etc. At least then it might be easier to reason where the damage and the oil might be linked.

The oil cooler cools the oil via heat transfer to the coolant, which also flows through the oil cooler ... so, yes, a failing gasket means mixing coolant and oil.

Yeah, I can go there. Odd that might start after the call fell off the lift, but perhaps that was all it needed.
