I don't have heat my 1989 G20 van. I was told by my mechanic that the heater valve was removed from the van and that the hoses were reconnected to each other so that it loops back in the system. I have gotten myself a new heater valve, but there are 4 hose connectors, 3 on one side, 1 on the other.
I don't know which hose goes to which connector. I have a Haynes manual, but it doesn't show the hose connections in the manual. Does anyone have a diagram? Or know exactly which hose from where connects to which hose connection on the heater valve?
Thanks,
George
