Eliminating the heaters loop -- what about the pump?
I'm eliminating the heater line that goes all the way from engine area to the two heaters. I'm just shortening that giant loop that included the two heaters for passengers into a much smaller loop in the engine compartment area. However, I noticed that there is a pump that was part of that giant loop in the engine area. If I shorten the loop, can I just eliminate that pump as well (if it's just for helping move fluid all the way back to rear of bus) or is it essential for the normal movement of fluid to supply the heater for the driver at the front of the bus, which I'd like to keep?
