Oil in the cooling resevoir

What is your question?

We did not know we had a problem. No problems with engine over heating. We had noises that sounded like fan belts so we took the van in and the pulleys were making noises and the part that goes to the cam shaft was really the problem. The mechanic phoned to let us know about the oil in the reservoir? No leaks noticeable but he said we were down on antifreeze.

How long has your 2002 Ford Windstar had this problem?

No idea.
