August 28, 201312 yr I have a 89 XT GL and I need to know the configuration of the coolant hoses into and out of the firewall for the heater core. Does the tube on the passenger side of the heater core receive or return the coolant from/to the motor? Edited August 29, 201312 yr by redXTwedgie
August 28, 201312 yr The water pipe going along the top of the block flows from the water pump, and then returns to the pipe in the intake manifold
