Cobalt L4-2.2L (2008)
Care/Cleaning
Use soap, hot water and a 100% cotton cloth to clean and polish the new wheels. If using a wheel cleaner, be sure to select one that will not harm the
wheel surface, such as GM Chrome and Wire Wheel Cleaner, P/N 1052929 (in Canada, use 10953202). Avoid car washes that use carbide tipped
brushes, as these may damage the wheel's finish. Periodically clean the backside of the wheel to remove road grime, brake dust and grease.
Balancing
Use MC-style balance weights on the inboard rim and stick-on weights mounted on the outboard-center of the rim (behind the spokes).
Vehicle Modifications
BCM Reprogramming
Important:
BCM reprogramming not required on the Chevrolet Cobalt SS Supercharged and the Chevrolet HHR.
For proper vehicle operation and to ensure coverage under the provisions of the New Vehicle Limited Warranty, the vehicle must be reprogrammed with
the correct calibration as soon as accessory wheels are installed.
After initiating the BCM setup procedure with the Tech 2(R), select "Change Options" then "Select Wheel Size". The wheel size selections will then be
displayed. Note that the current wheel size and tire RPO (17" QBU) will be highlighted. The new wheel size and tire RPO (18" QTJ) should then be
selected from the list to program the correct calibration. Select "Save Options" on each of the remaining screens until completed.
Important:
If original equipment tires/wheels are reinstalled, it will be necessary to reset the programming of the BCM to the original specifications.
Tire Label
Important
All tire and wheel packs are shipped with two different tire labels. The following is a breakdown on when each label should be used - dependent
upon the model:
-
Chevrolet Cobalt SS Supercharged vehicles DO NOT need a new label.
-
Cobalt/G5/Pursuit/G4 - Use tire label P/N 19165892 (road tire pressure of 220 kPa (32 psi)).
-
HHR - Use tire label P/N 19201200 (road tire pressure of 241 kPa (35 psi)).
After installing the recommended 215/45R18 tires, place the provided tire label on the vehicle. The new tire label should be located within the red box,
over the top of the original tire label found on the door jamb. To locate the label within the red box, use the upper and left hand edge of the red line as a
guide. When properly placed, the new tire label will obscure the original tire information. Be sure that the surface is clean and dry. The surface
temperature should not be less than 21°C (65°F). The label is provided as a guide for tire inflation pressures.
Tire Pressure Monitoring (TPM) System
To avoid system malfunctions, it is necessary to install tire pressure sensors in the accessory wheels. After the wheels are installed on the vehicle, it is
necessary to learn the new sensor identification codes/locations into the remote control door lock receiver (RCDLR). Please refer to the proper re-learn
procedure in SI.
