With the 82 manifold, I have the heater in parallel with the heater with "Y"s. The 63 chassis has a water shutoff valve; later engines leave the heater water on all the time and just move the hot air around. So I can't plumb my heater like a late-model. Same on the 195.6; with the heater OFF, no hot water flows. Worse, the heater return runs into a dedicated INLET in the water pump; the water pump pumps from TWO sources, the bottom of the radiator and the heater. It's an old car! -------------- next part -------------- An HTML attachment was scrubbed...
