Motor runs very quiet, very smooth, 82,000 miles. Have looked and checked everything but find no leaks. Parked there is no fluid loss only after being driven. Water temp is always in normal range in town or on hiway, never goes above 230 in town and hiway is normally about 200. Radiator doesn't appear to be rusty. Keep Prestone 50/50 filled to the top always.

    check your oil to see if it is milky if not not have the system pressure tested

    Thank you. I'm 82 and have driven the wheels off of a lot of cars so have already checked the oil and it is not milky. Thank you, I will have the system pressure checked. This is a GREAT site, wish I had found it years ago.
