question on radiator connections

[James McClure]

Kik. No, hooking the hose to the water pump will not decrease water flow. Read my above reply slowly one step at a time. You have A\C so there is a valve to shut flow of hot water thru heater core when temp on the heater is set to cold. This is to make the A\C operate better. It will also stop water flow over the propane evaporator. I would do this. Seeing as you have A\c leave the evaporator hooked up in parallel as it is now. Don't change the hose positions from radiator to the water pump. Leave the heater control set to cold. This will shut the valve greatly reducing water flow. It will not stop the flow entirely, but warm up will be faster. Still when the eng is cold evaporation will suffer no matter what you do. To bad you don't have TBI. GM's light trucks were available with propane fuel as an option and the TBI unit did all the work for you except high pressure propane regulation which was done back at the fuel tanks. With a little plumbing you can feed a TBI propane instead of gas or run a duel fuel setup. jim
