The coolant flush "how to" just says "tighten housing bolts." Does anyone have the torque specs for the 2 thermostat bolts? I'm being forced to rebuild/clean my duo-valve because it's decided to become super-sticky in the last few days. If cleaning doesn't work a new one is only $154 so not the end of the world. I printed the "how to" and have a new T-stat plus 2 gallons of G-05 on hand. The only thing I need is the torque spec for the t-stat bolts and I'll get cracking. Thanks, Matt
