The Ford Barn - View Single Post - How difficult would it be to convert this water heater from 12V to 6V?

My car came with a coolant powered heater in a box. It had been installed in the car before so the holes in the firewall were already there. I re-installed it but wanted to use the tap in the outlet neck instead of the adapter in the hose. So I make my own scoop by soldering a modified copper elbow into a brass pipe nipple. I have a thermostat, which is in the radiator hose. The heater works great even in the freezing temperatures we have had here recently. The car is insulated. It is a four door and the heat reaches the back seat. The heater is the boxy one available from the vendors. I put a ball valve in the line so that I can turn off the hot coolant to the heater in the summer.

I think there are different water pumps available that pump more coolant than others.
