There was a car at the Las Vegas Expo with this cooling system configuration. I installed it on my car but Minnesota has yet to get temperatures that would give it a test. It involves replacing the bleeder screw in the thermostat housing with a 1/8" pipe threaded hose barb. A hose is run from the barb to a ' T ' fitting installed in the small hose returning fluid to top of the fill bottle. I haven't thought of any reason why it wouldn't work but I have to tell you it hasn't received a proper test in my car yet. I don't know whose car it was that had this installed at the Las Vegas Expo but it was such a simple idea we should have all thought of it .
