My 2001 Buick Century seems to use a small amount of coolent. The overflow tank was about a quart low today. I changer the coolent at 75000 miles (87000 now). Does the 3.1 engine have a history of this problem. There are no leaks that I can see and have not seen any water in tailpipe after car is driven. thanks Ernis
