I agree, I'll boil my thermostats and make sure they work. They are both practically new, less than 200 miles each. I have not seen the "drill a small hole" suggestion, I assume it would be 1/8" or so in the thermostat somewhere. I think before I put it back in I will have somebody do a thorough back flush just to be safe
