Bus Heater Removal
This is the bus heater coolant flow lines and pump.
So I might have the flow direction reversed, but that shouldn't matter for this question.
I think that I can connect 1 to 5 with two 90s, some reused hose and 4 hose clamps.
My only real concern is if I can completely bypass that 12v pump between 3 and 5.
I think it's only needed for the heater circulation.
And the coolant will continue to circulate if I leave it out.
Also, I'll be introducing air into the system
Will this be sorted out after the fluid circulates a bit or is there something I should do to remove the air from the line?
