Section 12-02: Heating and Defrosting | 1996 F-150, F-250, F-350, F-Super Duty and Bronco, F-Super Duty Motorhome Chassis Workshop Manual |
Removal
The following illustrations show the heater water hose (18472) installations on the 4.9L (300 CID), 5.0L (302 CID), 5.8L (351 CID), 7.3L (445 CID), and 7.5L (460 CID) engines.
The following procedure applies to each of the installations.
Drain the coolant from the cooling system.
Loosen the clamps and remove the heater water hoses from the vehicle.
Cut a length of heater water hose from bulk stock which is the same length and diameter as that of the heater water hose that has been removed. Bulk hose will require some modification on vehicles with E4OD automatic transmissions because the "T" in the hose has a factory crimp for retention to the tee.
Installation
Route the heater water hoses as shown in the applicable illustration.
Install the heater water hoses on their fittings and tighten the attaching clamps to 2-3 Nm (18-27 lb-in).
Fill and bleed the cooling system. Refer to Section 03-03.
Check for coolant leaks and proper operation of the system.
