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
screen to the new radiator.

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
information.
