Re: Poppet Valve
the poppet valves are spring operated k , as the motor starts the impeller sucks water pushing it into the motor , that water has to go some where , next to the poppet valves is the therm-st k, when the motor is cold & the water has not reached temp & the therm-st is still closed , the pressure builds up pushes the poppet valves up, the spring compresses the valve opens up & the water goes out , also when the motor has reached temp the stat opens but does not handle the amount of volume that the impeller pumps when the rpm increases , that extra volume of water then goes out through the poppet valves & then out the exhaust . the whole idea to put the poppet valves there is to keep the water in the motor until it warms up , so if you start your motor & SUDDENLY take off the rpm picks up , more volume of water , its got to go some where , cause the pressure builds up, now remember you did not give the motor time to warm up for the thermostat to open up k if you gonna do that , poppet valves open water out & bobs your uncle , cheers m8t
what you can do is fit a **** hole in the thermostat cover , then when you see the water coming out , then you know your motor has warmed up , cause the thermostat has opened , then you ready to go.& at the same time it tells you the thermostat is working , cause you cannot see it opening .the water coming out , den you know for sure its working
