I had recently had a thermostat installed in my van by someone and apparently the gasket was messed up in the process by putting it in wrong. I was driving to the nursing home to drop my mother off to visit my father and the van started steaming. The Director of the nursing home tightened the bolts as much as he could with pliars. Then when I left the nursing home to get my child home (child is unable to walk and uses a wheelchair and try to find one taxi that can transport a young man in a wheelchair, especially on the weekend) the van started steaming again. I pulled off of the highway and drove to the autozone to borrow a socket wrench to tighten the bolts some more. When I went in the store and explained my dilemma, 2 of the employees found the problem and installed a new thermostat right there. They filled the radiator back up with coolant and would not allow me to tip them even surreptitiously:). I will tell everyone I know how helpful the staff were. I know, sounds like the perfect country and western song, but very true:)
