TYC 621540 Dual Radiator and Condenser Fan Assembly

Dual Cooling Fan Assembly for GM Applications

This TYC dual radiator and condenser fan assembly is built for vehicles that use a combined cooling package to move air across both the radiator and A/C condenser. It is a direct-fit replacement for select 2005-2006 Buick Terraza, Chevrolet Uplander, Pontiac Montana, and Saturn Relay applications with the listed cooling configurations.

• Radiator and condenser cooling fan assembly configuration
• Dual fan design for combined engine and A/C cooling airflow
• Shroud included for proper fan housing coverage
• Shroud material: PA+GF
• Fan blade material: PA+GF
• 1 male connector with 4 terminals

Fitment and Application Details

Compatible with 2005-2006 Buick Terraza, w/ Rear A/C; 2005-2006 Chevrolet Uplander, w/ Rear A/C; 2005-2006 Pontiac Montana, w/o Rear A/C and w/o Hvy Duty Cooling; and 2005-2006 Saturn Relay, w/ Rear A/C. This TYC 621540 is a practical replacement when the original dual fan assembly no longer maintains proper airflow through the radiator and condenser. The 621540 part number is also referenced in OE and aftermarket catalogs for the same application.

This part cross-references Dorman 620-976 and Partslink GM3115194 for the same application.

Common Problems This Part Can Address

• Engine temperature rising in stop-and-go driving
• Weak or inconsistent airflow across the radiator
• A/C performance loss at idle or low vehicle speed
• Noise or vibration from a worn fan assembly
• Cooling system operation issues caused by a damaged shroud or fan blade

Installation Notes and Tips

Verify connector style, terminal count, and cooling configuration before installation. Confirm rear A/C and heavy-duty cooling requirements where listed, since the Pontiac Montana application excludes heavy-duty cooling and the Buick Terraza, Chevrolet Uplander, and Saturn Relay listings specify rear A/C. Compare the original assembly to TYC 621540 to confirm mounting points and electrical connection match before replacement.

Quality Assurance

TYC manufactures this dual radiator and condenser fan assembly with PA+GF construction for the shroud and fan blades, supporting a durable OE-style replacement for the listed GM vehicles.
