Subject:
Supplemental Repair Required for Drive Motor Battery Coolant Radiator Replacement

Due to Stone/Foreign Material Impact
Models:
2011-2013 Chevrolet Volt

This bulletin replaces PI0727A. Please discard PI0727A.
Condition

Some customers may comment on coolant leaking from

the front of the vehicle. Further inspection will reveal

that the leak is coming from the drive motor battery

coolant radiator.
Cause

This condition may be caused by impact from stones/

foreign material.
Correction
3. Fabricate two mounting brackets for the additional

screen using 25 mm (1 in) x 100 mm (4 in)

aluminum stock with thickness between 1.59 mm

(0.0625 (1/16) in) and 3.18 mm (0.1250 (1/8) in).

This material can be obtained locally. A good

source for this material is Home Depot. The Home

Depot carries Everbilt 1 in. x 36 in. Aluminum Flat

Bar with 1/8 in. thickness, Model #44690 (Home

Depot Canada carries H. Paulin - Model

#142-642).

4. Remove any burrs on the cut surface(s) and round

the corners using a file.
For Vehicles Built Prior to November 01, 2011

In addition to replacing the radiator, replace the existing

grille screen with a taller screen. Also, add a second

grille screen to the front of the new radiator following

the procedure listed below. The installation of the

radiator grille screens will greatly reduce the chance for

stones/foreign material coming though the front grille

and making contact with the new radiator causing

damage.

For Vehicles Built On or After November 01, 2011

In addition to replacing the radiator and transferring the

existing grille screen, add a second grille screen to the

front of the new radiator following the procedure listed

below. The installation of the radiator grille screens will

greatly reduce the chance for stones/foreign material

coming though the front grille and making contact with

the new radiator causing damage.

1. Remove the damaged drive motor battery coolant

radiator. Refer to the Drive Motor Battery Coolant

Radiator Replacement procedure in SI.

2. Replace or transfer the existing radiator grille

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these

technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper

service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a

job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your

vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
