Ref. Pug 205 1.6 GTI I checked the expansion chamber today and found it low. I needed to add about 900cc to fill to max. I have not added any coolent for about 1 month and wonder if this is excessive? I don't use the car a lot, but do use it every day (ca. 6mls/day). I can't see any leaks. I do tend to drive down steep hills every day, and wonder if the coolent could get pushed out through the over flow pipe at the top of the expansion chamber - leads directly to the road. The running temp is/was quite normal. Any thoughts. Thanks.. A
