Hummer H1 Models Affected: Vehicles VIN 180123 and above
Vehicles VIN 180123 and above are built with an 8-blade fan P/N 06009790 and clutch assembly P/N 06009791 combination which produces less fan noise than the fan that it replaces. The clutch engages at a higher temperature than the original, and the 8-blade fan produces less noise than the original 10-blade fan without sacrificing cooling efficiency.
Note: Fan and clutch assemblies are designed to operate with the correct mating part. When servicing either a fan or clutch assembly, do not mix fan and clutch assembly parts. Use the parts listed in the table below with their mating parts.
