If it's an auto truck, the return to the radiator is correct. If standard, the return to water pump is correct. No clue as to why the difference in routing but that's the way it was done at the factory.

Jeff,
My theory is that having the heater hooked up to the radiator on an automatic causes the coolant to flow around the transmission cooler as it is located on the side where the heater hose hooks to the radiator. Jim |
