Detailed Description

Dorman 624-304 is an OE-style transmission cooler hose assembly for the lower outlet connection on select Dodge Ram trucks. It is built to move automatic transmission fluid between the transmission and the cooler while maintaining a secure seal at the threaded and quick-disconnect ends. This part cross-references Chrysler 52028769AC and Sunsong 5801201 for the same application.

Use this transmission line on 1997-1999 Dodge Ram 1500, Ram 2500, and Ram 3500 models with the auxiliary bypass configuration. It does not fit threaded applications, so confirming the connection style before ordering is important. The hose material, length, and temperature range support service in demanding underhood conditions.

What It Helps Fix

  • Transmission fluid leaks at the cooler line connection
  • Damaged or corroded lower outlet hose assemblies
  • Restricted fluid transfer between the transmission and cooler
  • Failed quick-disconnect or threaded line connections
  • Service issues on 1997-1999 Dodge Ram 1500, Ram 2500, and Ram 3500 lower outlet lines

Installation Notes and Tips

Verify the vehicle uses the outlet (lower) line with auxiliary bypass before installation. Confirm the end styles match the vehicle connection: female threads on one end and male quick disconnect on the other. This part is not flexible, so route and alignment should be checked carefully during replacement.

Quality Assurance

Dorman manufactures replacement parts to match original equipment fit and function for specific vehicle applications. This hose assembly is built from quality metal and rubber components to support leak-free transmission fluid delivery in the listed Ram truck applications.
