Where did you make the connections? You will need to tap into the heater circuit to get flow before the thermostat opens.

The heater is located above the rear deck of the van about 1 foot above the engine. I have run 5/8 line up through some holes that I cut in the floor of the rear deck. I plumbed into the coolant system but canąt get the coolant to run up through the heater and back out again(the heater is basically a little maze of metal pipe in a small area with barbs on either end). Now I didnąt run the van too long, probably about 5 or ten minutes) because I was worried about overheating, but the coolant wouldnąt run through the lines up through the heater and back down to the system). I know that the coolant is a low pressure system, but since itąs a closed system shouldnąt it have to run its course? Help. Dave |
