I am experimenting with a self engineered closed cooling system, problem is exhaust manifolds not getting enough coolant while thermostat is closed. I am using the old style thermostat housing,but have the screw on tee with the spring loaded check valve removed and plugged, the cap that feeds the exhaust manifolds is over top of the thermostat and does not get any flow until the thermostat opens, so that seems to be it, any thoughts ??? thank you
