Ticking Noise Inside Car – GM products

GM has issued a technical service bulletin (TSB) 06-06-02-002C to address Ticking Noise Inside Car on Passenger Side at Idle conditions. The TSB applies to the following vehicles:

2006 Buick Rendezvous, Terraza
2006 Chevrolet Impala, Malibu, Malibu Maxx, Malibu SS, Monte Carlo, Uplander
2006 Pontiac G6, G6 GT, G6 GTP, Montana SV6
2006 Saturn Relay with 3.5L or 3.9L V6 Engine

If you own one of these vehicles and notice a ticking or clicking noise inside the vehicle on the passenger side with the engine running and at idle, here’s the cause. The noise is usually a evaporative emissions purge valve completing a cycle. The purge valve may be grounding out internally, which creates creating a noise path through the coolant inlet and outlet hoses/pipes. GM recommends the following procedure to fix the problem.

1. Drain the cooling system. Refer to Draining and Filling Cooling System in SI.
2. Remove the intake manifold cover, if equipped. Refer to Intake Manifold Cover Replacement in SI.
3. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in SI.
