  • Q:

    Where exactly does this hose go in the Ford 5.4 L engine? Is it the hose that runs underneath the intake manifold from the front of the engine to the rear towards the heater?

      The heater hose normally runs along the passenger side of the engine, back towards the firewall. To access, loosen the hose clamps on both heater hoses where they connect to the heater core inlet and outlet at the firewall using the screwdriver. Slide the clamps away from the hose ends. Follow the hoses to the heater control valve and intake and loosen the hose clamps at those ends as well with the screwdriver. Slide those clamps away from the hose ends. Pull the hose ends off the heater core inlet and outlet by hand. If the hoses do not slide free easily, insert the tip of the mechanic's pick between the hose end and the heater core inlet and/or outlet and slide the tip all the way around the hose end to free them from the heater core. For any further assistance please feel free to call 1-877-238-2623 and one of our representatives will gladly assist you with any questions or concerns you may have.
