You fixed it quickly, but I wasn't sure. I took it Friday just before closing and it seemed right. Saturday morning I needed to drive to Washington, D.C. When I got in the car at 6:00 A.M., the low coolent light was back and the coolent tank was empty! But there was no coolent on the ground? I used my other car and, as I thought about it I realized that you hadn't topped it off after you ran it and it sucked the tank full into the block. I filled it Saturday afternoon, warmed it up, there were no leaks, and the tank stayed full. Success on the first try!!
