Dorman 624-731 Automatic Transmission Oil Cooler Hose Assembly - Inlet
Automatic Transmission Oil Cooler Hose Assembly
Dorman 624-731 is a replacement automatic transmission oil cooler hose assembly built with metal and rubber components for fluid transfer between the transmission and the transmission oil cooler. It uses male quick disconnect ends on both sides and a molded hose shape to support a secure, leak-resistant connection in the transmission cooling circuit.
- Replacement automatic transmission oil cooler hose assembly
- Metal and rubber construction
- Male quick disconnect ends on both sides
- Molded assembly with flexible routing
- Silver hose finish
- Maximum working pressure: 500
- Operating temperature range: -40 Deg. F to 329 Deg. F
Built for Transmission Fluid Routing
This Dorman transmission oil cooler hose is made to move critical automatic transmission fluid between the transmission and the cooler while maintaining a secure seal at the connection points. The 38.6-inch molded assembly uses quick disconnect fittings with a 0.47-inch inside diameter at each end, helping preserve proper line routing and connection integrity in the cooling system. Part number 624-731 is a direct replacement-style solution for service work where the original hose has aged, cracked, or begun to leak. This part cross-references OE number 15058948 for the same application.
What It Helps Fix
- Transmission fluid leaks at the cooler line
- Cracked, hardened, or damaged hose sections
- Loose or worn quick disconnect connections
- Restricted fluid transfer between the transmission and cooler
- Heat-related deterioration in the transmission cooling line
Installation Notes and Tips
Inspect the mating transmission and cooler ports before installation and confirm the quick disconnect ends are fully seated. Verify line routing matches the original molded shape to avoid contact with hot or moving components. Because fittings and seals are not included, reuse or replace related sealing components as required by the vehicle service procedure. Confirm vehicle-specific application details before ordering, especially for Chevrolet Silverado, GMC Sierra, and other models that use this style of transmission cooler hose assembly.
Quality Assurance
Dorman replacement parts are built to match the function of the original cooling line with materials selected for fluid handling and temperature resistance. Part number 624-731 is engineered as a service replacement for vehicles that require this transmission oil cooler hose configuration.
