# 07255 - (10/04/2007
Models:
2008 Chevrolet Cobalt
2008 Pontiac G5
THIS PROGRAM IS IN EFFECT UNTIL OCTOBER 31, 2008.
Condition
On certain 2008 model year Chevrolet Cobalt and Pontiac G5 vehicles, the hose connecting the surge tank to the thermostat cover may not seal sufficiently. This could result in a coolant leak at the thermostat cover. If enough coolant leaks out, the engine coolant temperature warning light will illuminate. If the vehicle is driven with the light illuminated, it could result in engine damage.
Correction
Dealers are to install an additional clamp to the hose at the thermostat cover.
Vehicles Involved
Involved are certain 2008 model year Chevrolet Cobalt and Pontiac G5 vehicles built within the VIN breakpoints shown.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned.

Courtesy Transportation
The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
