TBS on Belt Noise

#09-06-01-013A: Accessory Drive Moan/Growl/Groan/Whine Noise When A/C Compressor Cycles (Replace Accessory Drive Belt) - (Jan 13, 2010)

Subject:Accessory Drive Moan/Growl/Groan/Whine Noise When A/C Compressor Cycles (Replace Accessory Drive Belt)

Models:2010 Chevrolet Camaro
With 3.6L Engine (RPO LLT)
Please Refer to GMVIS
Excludes Vehicles Built After August 3, 2009


Attention: This condition is likely to be misdiagnosed as an A/C compressor due to the condition only being noticed during A/C compressor cycling.

This bulletin is being revised to include vehicle build date information. Please discard Corporate Bulletin Number 09-06-01-013 (Section 06 - Engine).
<A href="#ss1-2382089">Condition

Some customers may comment on an accessory drive belt moan, growl, groan or whine noise that may be present when the engine A/C compressor cycles at moderate to high head pressures at engine Idle and throughout the RPM range.
<A href="#ss2-2382089">Correction

Important: VEHICLES BUILT AFTER AUGUST 3, 2009 ALREADY HAVE THE NEW POLYESTER BELT AND SHOULD NOT BE CHANGED.
An improved accessory drive belt, P/N 92242956, has been introduced. This new belt features a polyester cord to reduce the stiffness over the current production Kevlar cord belt. This belt significantly reduces this condition. Vehicles built after August 3, 2009 already have the new polyester belt and should not be changed.
  1. Verify that the vehicle has this condition.
  2. Replace the accessory drive belt with P/N 92242956. Refer to Drive Belt Replacement in SI.
  3. Verify the condition is corrected.
  4. If the condition is still present, refer to Noise Diagnosis - Air Conditioning (A/C) System in SI.
