Detailed Description
The SKP SK624124 is designed for transmission cooling circuits that use an auxiliary cooler or heavy-duty cooling setup. By carrying hot transmission fluid away from the transmission and through the cooler, the hose assembly supports temperature control in demanding driving conditions. Fitment includes 1999-2006 Chevrolet Silverado 1500, 2000-2006 Chevrolet Tahoe, 1999-2006 GMC Sierra 1500, and other listed Cadillac, Chevrolet, and GMC applications. The SK624124 is a practical replacement when the original hose is leaking, cracked, or no longer maintaining proper flow. This part cross-references Dorman OE Solutions 624-124 for the same application.
Common Uses
- Leaking transmission cooler hose connections
- Cracked or deteriorated hose material
- Restricted fluid flow in the transmission cooling circuit
- Overheating concerns related to cooler line failure
- Replacement during transmission cooling system service
Installation Notes
Verify the vehicle’s cooling configuration and connection style before ordering. Fitment varies by model, year, and whether the vehicle uses an auxiliary cooler or an inlet upper connection with RPO code KNP. Match the hose routing and position to the listed application for proper installation.
