Detailed Description

This Dorman transmission cooler hose is engineered to move transmission fluid between the transmission and the cooler while maintaining a secure, leak-resistant connection. The hose uses a male quick disconnect on one end and a hose barb on the other, matching the listed OE-style connection points for the upper inlet line. If you are servicing a 1997-1999 Ford Taurus or 1997-1999 Mercury Sable with an auxiliary oil cooler, 624-223 provides the correct fitment for the specified position.

The hose is non-flexible and built for stable routing in the transmission cooling circuit. Its rubber construction and metal reinforcement support operation across a wide temperature range, making it suitable for demanding underhood conditions.

Vehicle Fitment

• Loose or damaged quick-disconnect or hose-barb connections
• Restricted fluid transfer between the transmission and cooler
• Service replacement for a worn upper inlet transmission line

Installation Notes and Tips

Confirm the vehicle has an auxiliary oil cooler and verify the inlet (upper) line position before installation. Inspect the mating connections, routing path, and surrounding cooler components for wear or damage before replacing the hose. Match the end styles and length to the original line to ensure proper fitment on the Ford Taurus or Mercury Sable application.
