What does the temp gauge read? With the rad. cap off and engine warm do you see a flow?
Where ever you put it , you don't state how you plumbed the system.hate to sound dumb, where is rad.cap on reverse flow rad?????????
Reverse rotation pump only spins the opposite way , coolant flow through engine is still the sameAre you talking about a reverse rotation water pump?
True but he stated the heater worked fine. Im thinking it has a 180 thermostat.Are you talking about a reverse rotation water pump? Normally a cold lower hose means that your thermostat is not opening. If your temp sensor is not in coolant, it may not be reading properly. Good luck
