So I am ditching my stock radiator for a monster aluminum one since I am having some cooling issues. The new one doesnt have the fitting for the heater hose. So can I just hook it up to the top fitting on the waterpump?? With my propane I need the heater hoses so its hooked up like this : intake----vaporizer-----radiator. So can I hook the radiator side hose to the waterpump???
