SPECIAL COVERAGE
SUBJECT:

Special Coverage Adjustment - Engine Cooling Fan Motor

MODELS:

2011-2015 Chevrolet Caprice
2012-2016 Chevrolet Impala
Equipped as Police Patrol Vehicles (RPO 9C1 or 9C3)

This bulletin has been revised in the Warranty Transaction Information section. The labor code for
replacing the engine coolant fan motor on vehicles still covered under applicable new vehicle limited
warranty has been updated. Please discard all copies of bulletin 14588B.
CONDITION
On some 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
underhood bussed electrical center
(UBEC).
SPECIAL COVERAGE ADJUSTMENT
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.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties
section in GM Global Warranty Management system. Dealership service personnel should always
check this site to confirm vehicle involvement prior to beginning any required inspections and/or
repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles
may be involved regardless of description or option content.

SERVICE PROCEDURE
Note: There are multiple Technical Service Bulletins related to the coolant fan motors in these
vehicles. Please refer to SI for proper diagnostic procedures.
CAPRICE ONLY
1.

Using the diagnostic steps in SI 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 SI.

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. After completing the wiring
harness installation, proceed to step #1 below.
1.

Using the diagnostic steps in SI, determine if the engine coolant fan motors need to be
replaced.

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.

4283372

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.

4283375

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:

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.

cut wire ends leading to PCM. Apply heat to the heat shrink tubes to seal the splices.

4283386

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.
