Thanks Steve I appreciate the help...my heater valve has two outlets on one side of the valve and one outlet on the other. The single comes from another main supply valve according to my Haynes manual. My question is can I just crimp the single inlet as you stated and then drive. I'm just not familiar with the flow directions. The top of the valve has two electric solenoids. I assume these are the ones that are directed the module to control flow? Thanks again I'll post after following your advice.
