Coolant Flow Diagram

Tom Z · March 2, 2012

Anyone have a coolant flow diagram for an 08 Ranger 4 cylinder? I want to install a flush tee and can't tell which is the heater inlet hose.

Thanks

i dont have a diagram but you can feel the temp of the hose. the inlet will get hot before the return.

make sure your HVAC controls are off and the temp control is on cold. that will keep the hot engine coolant from entering the heater core.

then get the engine up to operating temp. then have an assistant turn the heat on inside the car. the inlet will open allowing hot coolant into the heater core helping you find the inlet

Thanks, never thought of doing it that way! Good idea.
