Detailed Description

This automatic transmission oil cooler hose assembly is built to move critical transmission fluid between the transmission and cooler circuit while maintaining a secure seal. The metal and rubber construction supports a stable, leak-resistant connection in applications where the line runs from the auxiliary cooler to the radiator on the passenger side. Dorman 624-071 is listed for 1993-1995 Chevrolet C2500, C2500 Suburban, C3500, K2500, K2500 Suburban, and K3500, plus 1993-1995 GMC C2500, C2500 Suburban, C3500, K2500, K2500 Suburban, and K3500, along with 1995 Chevrolet C35.

Common Problems This Part Can Address

• Transmission fluid leaks at the cooler line connection
• Cracked, corroded, or damaged original oil cooler hose assembly
• Restricted fluid transfer between the transmission and cooler
• Improper sealing at the male thread or quick-disconnect ends
• Heat-related deterioration in the transmission line routing

Installation Notes and Tips

Verify the vehicle’s year, make, model, and cooler-line routing before installation. This assembly uses a male-threaded end and a male quick-disconnect end, so confirm the connection style on the vehicle side before ordering. The line is not flexible, so align the routing carefully to match the original path from the auxiliary cooler to the radiator on the passenger side.
