- MULTIPOINT INSPECTION – CHECK ALL LIGHTS
- Customer previously reported a loud pulley-type noise from the engine bay. Previous Findings & Repair: Initial inspection indicated possible alternator-related noise. The alternator was tested and replaced with customer authorization. Follow-Up Inspection Results: After replacement of the alternator, the engine was re-evaluated for abnormal noises. All pulleys were probed and inspected. At this time, no pulleys exhibit excessive noise, abnormal play, or signs of bearing failure. The accessory drive system appears to be functioning normally. Additional Findings: Vehicle is equipped with an aftermarket cold air intake system. During operation, increased intake and supercharger noise is present. This is consistent with aftermarket intake systems, which amplify normal supercharger sound due to reduced intake restriction and lack of factory sound dampening. Conclusion: At this time, no mechanical faults were found within the pulley or accessory drive system. The noise the customer is experiencing is most likely normal supercharger/intake noise amplified by the aftermarket cold air intake. Recommendations: No repairs are necessary at this time. If the customer prefers a quieter operation, recommend reinstalling the factory intake system to reduce intake and supercharger noise
