More accurately, from right rear of intake manifold (the manifold is the supply of hot coolant) to heater core inlet, to heater core outlet, to water pump suction port.Same. Mines a 95, and hoses go from water pump, to heater core, to top rear of intake manifold, with no valve in-between.
The hot coolant comes OUT of the back of the intake manifold, and re-enters the engine at the water pump.
Some vehicles have the outlet of the heater core plumbed directly into the "cool" tank of the radiator. The cool tank of the radiator is connected to the suction side of the water pump via the lower radiator hose.
