Bill spent quite a bit of time testing the cooling system to see why we were getting such a burst when the thermostat released. We even bought a new thermostat but Bill tested the one that came with the car and it worked. His solution was to drill three holes in the thermostat to allow constant flow. He thinks we have it figured out but I will monitor the coolant level and keep an eye on things as the season unfolds.
Bill can back me up...I'm more involved than I look!
