my van overheated today even when I was going down the highway at 60 mph. I pulled over and the coolant had backed up into the little plastic tank and was leakiing underneath the engine. Is it the waterpump or what? I had it towed to the little shop in my town and I would like to know what might be wrong with it going into the repair.
Thanks, Ed
