REMOVAL & INSTALLATION

Puller Type

NOTE: It may be simpler to remove the cooling fan(s) with the radiator as an assembly.

1. Disconnect the negative battery cable.
2. Inspect the cooling fan and take note of any wires, hoses or A/C lines which may hamper fan removal. Also at this time, decide whether it is necessary to remove the fan along with the radiator or not.
3. Position aside all wires, hoses and A/C lines for fan removal. It may not always be possible to create enough clearance for fan removal by simply moving these obstructions aside; often they must be disconnected. If any cooling system lines must be disconnected, drain and recycle the engine coolant. If any of the A/C lines must be disconnected, the A/C system will need to be discharged and evacuated by a MVAC-trained technician using an approved recovery machine.

4. Disengage the cooling fan wiring harness connector.
5. If the fan can be removed without the radiator, perform the following:
   1. Loosen the mounting fasteners. Usually there are two nuts or bolts along the top edge of the cooling fan shroud and either two retaining clips or bolts along the bottom edge.
   2. Carefully lift the fan up and out of the engine compartment, making sure that no wires or hoses get hung up on it.
6. If it is necessary to remove the radiator for fan removal, perform the following:
   1. Disconnect all cooling system hoses from it after draining the cooling system.
   2. Locate all of the radiator mounting fasteners (usually two or more nuts or bolts along the top, possibly two along the bottom).

      NOTE: Quite a few radiators are secured along the bottom by two posts which fit into rubber grommets. The rubber grommets help isolate the radiator from harsh vibrations in the frame. If no nuts or bolts can be located along the bottom of the radiator, chances are that the radiator is secured with the posts and grommets.

   3. Lift the radiator and cooling fan up and out of the engine compartment together.
   4. Separate the cooling fan from the radiator by removing the attaching fasteners.

      To install:

7. If applicable, install the cooling fan on the radiator.
8. Install the cooling fan and shroud assembly (also the radiator if necessary). Tighten the fan shroud mounting bolts.
9. Reattach all wires, hoses and A/C lines as applicable. If the A/C lines were detached, the system must be evacuated and recharged by a MVAC-trained technician.
10. If drained, refill and bleed the cooling system.
11. Reattach the cooling fan electrical harness connector.
12. Connect the negative battery cable.
13. Start the engine and check for leaks.
14. Verify the operation of the cooling fan(s).

Pusher Type

Vehicles that utilize the pusher type of electric cooling fan, may require the removal of the grilles and/or upper radiator shroud in order to gain access the fasteners that mount the fan assembly in the vehicle.

1. Disconnect the negative battery cable.
2. Access the cooling fan.
3. Label and disconnect the cooling fan electrical harness.

   NOTE: It may be necessary to loosen the mounting bolts for the A/C condenser to the body

4. Remove the fasteners that mount the cooling fan to the A/C condenser or radiator.
5. Lift the cooling fan out of the vehicle.

   To install:

6. Insert the cooling fan into the vehicle.
7. Mount the cooling fan to the A/C condenser or radiator
8. Connect the cooling fan electrical harness.
9. If removed, install any shrouding or grills.
10. Connect the negative battery cable.
