Because this truck came equipped with a trailer towing package, the water bypass joint needed to be replaced and some of the oil cooler lines extended. After disconnecting the heater hose from the bottom, the bolts were loosened and the old piece removed. The new piece comes with a barb for an extra heater hose leading to the coolant pump.
