Car overheated and saw no fluid added 50/50 prestone anti-freeze. Drove it for a few days it happened again. Saw that fluid was half gone added more tested it by driving with the air done it was fine. I also checked the fans. It's a chrysler concord 99 3.2 l v6 engine and it has a pressurized system. Could it be that maybe there was an air bubble and it needed more liquid or the themostat or a hose that might have a small leak even though I did not see a leak on the ground? thanks
