#PIC5223: Wheel Center Caps Loose Or Missing - (Aug 3, 2009)
Subject: Wheel Center Caps Loose or Missing
Models: 2008 - 2009 Chevrolet Cobalt
2008 - 2009 Pontiac G5
with 16" or 17" Aluminum Wheels (RPO NZ0 or PFE)
--------------------------------------------------------------------------------
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some center wheel caps for the 2008 or 2009 Chevrolet Cobalt or Pontiac G5 with aluminum wheels may have poor retention which could cause them to be loose or fall out.
Recommendation/Instructions:
Replace any missing center caps.
Reinstall the loose or missing center cap with a bead of RTV (P/N 12378521 or equivalent [in Canada, P/N 88901148]) applied around the inside of the wheel bore and apply adhesion promoter (P/N 12378462 [in Canada, P/N 10953554]) and RTV (P/N 12378521 [in Canada, P/N 88901148]) around the inside of the cap teeth before inserting the cap. RTV should cover approximately 3 "snap fingers" on each side (2 beads) located near the "break-over" point of the snap finger ramp.
If you find one loose center wheel cap, apply RTV on all four center caps.
Important: DO NOT reinstall loose center caps or install new ones without RTV sealer.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
