Radiator

Removal

  1. Drain the cooling system. Refer to Cooling System Draining, Filling and Bleeding in the Cleaning and Inspection portion of this section.

  1. On a Bronco vehicle, remove air cleaner intake tube.

  1. Remove the radiator overflow hose (8075) from the radiator (8005).

  1. Position the upper and lower hose clamps toward the middle of hoses. Remove the upper radiator hose (8260) and lower radiator hose (8286) from the radiator connectors.

  1. Remove the heater water bypass hose (E4OD-equipped vehicles only) located directly below the overflow nipple on the radiator outlet tank.

  1. Disconnect the two automatic transmission (if so equipped) oil cooling lines from radiator fittings.

  1. Remove the two radiator upper attaching screws or bolts.

  1. Tilt the radiator back approximately 25mm (one inch) and lift directly upward, clear of the radiator support bracket (8052) and fan blade (8600).

  1. If either upper radiator hose or lower radiator hose is to be replaced, position clamp toward the middle of hose and slip the hose off the connection with a twisting motion.

  1. Lift the fan shroud off the fan and remove from the vehicle.

Installation

  1. Inspect the radiator mounting insulators (8124). Replace if necessary.

  1. Position fan shroud on fan until radiator is installed.

  1. If either upper radiator hose or lower radiator hose has been replaced, install on engine (6007) with index arrow in line with mark on fitting on engine. Position clamps.

  1. Install the heated water bypass hose (E4OD-equipped vehicles only) to the nipple located below the overflow tank.

  1. Position radiator into engine compartment to radiator support (16138), being careful to clear fan.





  1. Install two upper attaching bolts or screws. Tighten to 11-14 Nm (8-11 lb-ft).

  1. Connect the two automatic transmission (if so equipped) oil cooling lines to radiator connectors and tighten tube nuts to 16-24 Nm (12-18 lb-ft) or clamps to 4-5 Nm (35-44 lb-in).

  1. Attach upper radiator hose and lower radiator hose to radiator. Position hose on radiator connection so that index arrow on hose is in line with mark on connection. Position clamps.

  1. Position fan shroud on the lower retainer clips and attach the top of the fan shroud to radiator with two screw and washer assemblies. On F-Super Duty Motorhome Chassis vehicles install the two lower screws. Tighten screws to 6-8 Nm (53-71 lb-in).

  1. Attach radiator overflow hose from radiator coolant recovery reservoir (8A080) to radiator.

  1. Install air cleaner intake tube (Bronco only).

  1.  WARNING: DO NOT STAND IN LINE WITH OR NEAR RADIATOR FAN BLADE WHEN ENGINE IS RUNNING.

    Refill cooling system. Refer to Cooling System Draining, Filling and Bleeding in the Cleaning and Inspection portion of this section.
