If you add coolant to the resevore instead on fill plug will this cause any real damage? Car overheated after adding to the "cool fill line"in the resevore. After researching the manual I followed the proper procedure by removing the fill plug and it worked fine until it warmed up. Could this be caused by air in the system?
have the same problem?
