Reliable Automatic Transmission Oil Cooler Hose Assembly

The Dorman 624-041 automatic transmission oil cooler hose assembly is engineered to provide a durable and precise fit for select Buick, Cadillac, Oldsmobile, and Pontiac models. Designed with a metal tube construction, this hose assembly ensures consistent performance under a wide range of operating temperatures.

  • Durable metal tube hose material for long-lasting use
  • Natural hose color with a 1-foot length for accurate fitment
  • End 1 features male threads; End 2 has a hose barb connection
  • Maximum working pressure of 100 PSI for reliable fluid transfer
  • Operates effectively between -40°F and 329°F
  • Non-flexible design for secure and stable installation

Product Details and Specifications

The Dorman 624-041 transmission line is constructed from a sturdy metal tube, providing resistance to wear and heat commonly encountered in automatic transmission cooling systems. Its natural color and 1-foot length make it suitable for precise replacement needs. The hose assembly connects via male threaded fittings on one end and a hose barb on the other, ensuring compatibility with factory transmission cooling components. Rated for a maximum working pressure of 100 PSI, this hose assembly maintains integrity under typical transmission fluid pressures. It is designed to operate within a temperature range from -40°F to 329°F, accommodating the thermal demands of transmission cooling circuits. The hose is rigid rather than flexible, which helps maintain a secure connection and prevents kinking or collapse during operation.

Compatible Vehicles and Applications

This automatic transmission oil cooler hose assembly is compatible with various Buick, Cadillac, Oldsmobile, and Pontiac vehicles, including models such as the Buick LeSabre and Park Avenue, Cadillac DeVille and Fleetwood, Oldsmobile Delta 88 and 88, and Pontiac Bonneville. The Dorman 624-041 is an appropriate replacement part for maintaining proper transmission fluid cooling in these vehicles, helping to ensure smooth transmission operation and longevity.

  • Transmission fluid leaks due to worn or damaged hoses
  • Overheating issues caused by inefficient transmission fluid cooling
  • Cracked or corroded hose assemblies affecting fluid flow
  • Pressure loss in transmission cooling lines
  • Replacement of original equipment hoses during transmission service

Installation Notes and Tips

When installing the Dorman 624-041 hose assembly, ensure that the male threaded end and hose barb end are properly connected to their respective fittings to prevent leaks. Since the hose is non-flexible, carefully align it to avoid stress or bending that could cause premature failure. Inspect surrounding components for wear or damage during installation to maintain overall transmission cooling system integrity.
