Ken Welter >>>>Definitely put a weeper hole in the thermostat. Apparently the stock Mazda thermostats have a 'jiggle pin' in a hole to allow bleeding of air. I have an aftermarket thermostat that has no hole, and it caused a lot of difficulty getting the coolant in and the air out for the dyno run. Finally just took it out, did all our runs, and then got a different thermostat with a 'jiggle pin' for the runs to measure flow with the thermostat. Al
