2011-2015 model year Chevrolet Caprice and 2012-2016 model year Chevrolet Impala police patrol vehicles, idling the engine for extended periods of time can prematurely wear the engine-cooling-fan motor.

In this condition, the motor may fail to operate or operate noisily. This condition can also damage motor-control relays in the vehicle’s underhood bussed electrical center (UBEC).

This special coverage covers the condition described above for a period of 6 years or 100,000 miles (160,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Dealers are to diagnose and replace fan motors per PI1384 regarding the semi-annual preventative maintenance check for police vehicle cooling fans. The repairs will be made at no charge to the customer.

For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after July 23, 2015, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to July 23, 2015, must be submitted to the Service Contract provider.

Service Procedure

Note: There are multiple Technical Service Bulletins related to the coolant fan motors in these vehicles. Please refer to Service Information for proper diagnostic procedures.

Caprice Only

1. Using the diagnostic steps in Service Information and Technical Service Bulletins, determine if the engine coolant fan motors need to be replaced.
2. If necessary, replace the coolant fan motors. Refer to Engine Coolant Fan Motor Replacement in Service Information.

Impala Only

Inspect the vehicle and service history to determine if the updated engine cooling fan wiring harness kit has been installed.

• If the revised engine coolant fan wiring harness has been installed, proceed to step #1 below.
• If the revised engine coolant fan wiring harness has NOT been installed, proceed to the Engine Cooling Fan Wiring Harness Installation section below.

1. Using the diagnostic steps in Service Information, determine if the engine coolant fan motors need to be replaced.
2. If necessary, replace the coolant fan motors. Refer to Engine Coolant Fan Motor Replacement in Service Information.

Engine Coolant Fan Motor Wiring Harness Installation

1. Disconnect the battery.
2. Remove the passenger side motor compartment front cross brace.

3. Remove the passenger side head lamp and the G101 ground bolt.
4. Disconnect the cooling fan wiring harness from the fans. Carefully disengage the retainer clips of the factory harness from the fan shroud. Use care to not damage the attachment features on the shroud, they will be reused.

5. Cut the cooling fan wiring branch at the headlamp opening area. Measure approximately 100mm from the main wire bundle. This branch contains the White, Black, Grey and Light Blue wires. Remove and discard the cut off fan harness.

6. Seal the four cut leads of the harness with four Duraseal Splice Tubes. Wrap the cut harness section with electrical tape to prevent moisture damage.

7. Route the new harness along the bottom of the fan shroud and engage the retainer clips into the mounting holes in the fan shroud.
8. Add Nyogel Lube to the terminals of both fan connectors on the new harness. Connect the fan connectors to the fan motors.
9. Route the new fan harness into the passenger side headlamp pocket area.

10. Route the harness through the headlamp area, inboard of the windshield washer fluid bottle, then outboard of the UBEC. Loosely install three tie straps, do not tighten the straps at this time.

11. Route the fan control wires (D-GN and D-BU) outboard of the UBEC to the engine harness, in the area where it enters the UBEC. Place the two harness fuses outboard of the UBEC.

12. Route the ground wire of the new harness through the passenger side head lamp opening and install over the G101 ring terminal (see below). Reinstall the ground bolt.

Tighten

Tighten the bolt to 10 +/- 2 Nm.

13. Remove the UBEC cover.

14. Remove the nuts from both UBEC battery studs, and remove all ring terminals. The convoluted conduit on the left ring terminal may not be present in some vehicles. It may appear as double-crimped fusible links to a single ring terminal.

15. Unscrew the four UBEC connector bolts and remove the UBEC.

16. Remove the engine harness connector and turn over to access the wiring.
17. Find the fan control wires in the engine harness: D-GN wire, 22 AWG, circuit 335 (Cavity H7), and D-BU wire, 22 AWG, circuit 473 (Cavity C7).

Note: There is 1 additional D-GN/WH stripe wire (22 AWG) and 1 DK-GN wire (20 AWG). The required D-GN wire is a 22 AWG wire.

18. Extract the D-GN and D-BU control wires and cut the wires. Stagger wire cut points to permit splices to lay end-to-end. Apply electrical tape to the wire ends going into the UBEC connector.

19. Splice the new fan relay control wires from new harness (D-GN and D-BU) to the matching cut wire ends leading to PCM. Apply heat to the heat shrink tubes to seal the splices.

20. Return the spliced wires into the UBEC splash shield between the connectors, routing them so they will not be crushed during the UBEC re-installation. Using a tie strap, secure the spliced wires near the existing tie strap on the engine harness connector.

21. Use electrical tape to keep the two wire leads in place during UBEC re-installation.

22. Route the two wires out of the UBEC.
23. Install the UBEC back in place and tighten the 4 connector bolts.

Tighten
Tighten the bolt to 6 +/- 2 Nm.

24. Re-install all original ring terminals to the UBEC battery studs. Install the 2 ring terminals (RED) of the new harness to the studs as follows: route the shortest ring terminal lead to the RH UBEC stud and the longest lead to the LH battery stud. Orient the ring terminals with the crimp up and displaced angularly to permit all the ring terminals to lie flat. Reinstall the nuts.

Tighten
Tighten the nuts to 15 +/- 3 Nm.

25. Remove, and discard, both Cooling Fan Fuses in UBEC. They are on each side of the Cooling Fan Relays.
26. Reinstall the UBEC cover.

27. Position the relay and bracket assemblies on the upper radiator support as shown, Mark the drill location with a paint pen. Note that the double relay bracket is located on the passenger side of the upper engine mount.

Note: Avoid drilling spot welds in the radiator support.

28. Using a 5mm drill bit, drill the 2 relay bracket mounting holes in the upper radiator support. Treat all exposed metal with GM Super Lube®, or equivalent.
29. Install the relay brackets to the radiator support using two (2) rivets.
30. Re-install the passenger side cross brace.

Tighten
Tighten the nuts to 10 Nm.

31. Check all routing, especially the position of the J-Case fuse holders and the leads to the UBEC near the cross brace.

32. Tighten the 3 tie straps after checking all routing of the new harness.
33. Install the passenger side head lamp.
34. Reconnect the negative battery cable.

Tighten
Tighten the nut to 6 +/- 2 Nm.

35. Perform a test of the fan harness by turning the engine ON, and activating the A/C. Both fans should start operating instantly.
