Detailed Description

Dorman 624-354 is an automatic transmission oil cooler hose assembly engineered for 1997-2001 Jeep Cherokee models.

What It Helps Address

  • Transmission fluid leaks at a damaged cooler line
  • Cracked, corroded, or worn hose sections
  • Restricted fluid transfer between the transmission and cooler
  • Failed quick disconnect connections
  • Heat-related deterioration in the transmission cooler hose

Installation Notes and Tips

  • Verify the routing before installation: auxiliary cooler (passenger side) to transmission, or lower transmission-to-radiator line.
  • Confirm the vehicle is a 1997-2001 Jeep Cherokee and check whether it has an auxiliary oil cooler.
  • Inspect the mating quick disconnect fittings and surrounding cooler lines for wear or contamination before assembly.
  • Match the hose length and routing to the original line to avoid strain on the connections.

Quality Assurance

Dorman replacement parts are built to match the application-specific requirements of the original transmission cooler line layout. The metal and rubber construction, pressure rating, and temperature range support dependable fluid transfer in Jeep Cherokee cooling-system service.
