I don't know of a difference with a truck's system, but the passenger car and light commercials have the valve on the head at the output to the heater hose, which then routes to the bottom of the heater core, then out the top and down to the lower radiator hose. This routing is important for two reasons: 1, to receive the hottest water possible, and 2, to prevent air pockets in the heater core.
