on the heater system, which side is the send and which side is the return? What I mean is which side is the engine pumping into the heater core and which side is the return back into the engine? All hoses are disconnected and I have a different engine in the car now so I can't look at where the hose is going. I would guess that the heater control valve would shut off the water pumping in from the engine and the return would be on the other side. Neither the Chiltons nor the Haynes manuals have a cooling flow diagram. Thanks!

I can tell you on my 2.2 the upper one or drivers(valved) goes to the top of the engine that would have to be return line on my 2.2l. The lower left one goes to the engine metal tube because that one dribbles a little on me and I have to tighten it once in a while. |

And the other one that is closer to the passenger side and lower connects to the metal tubing that wraps around the engine towards the waterpump? The 5sfe and the 3sgte have the same waterpump setup, it pumps into the engine first and the two metal tubes that wrap around the engine are the return lines. So if what you are saying is correct then the water will pump through the engine and out of the coolant neck (part above the trans that is close to the distributor) into the shut-off valve side, and then return out of the other one that is closer to the passenger side, feeding into the coolant pipes to go back to the waterpump. -------------------- -Jay
