What It Helps Fix

• Leaking transmission cooler line connections
• Broken or worn quick-connect fittings
• Damaged threaded cooler line attachment points
• Loss of transmission fluid at the radiator connection
• Need for a full line assembly replacement when only the connector has failed

Installation Notes

Verify the line style, thread size, and connector type before installation. This connector uses a straight steel design with a quick-disconnect end and a male-thread end, and no thread sealer is present. Confirm routing to the radiator and match the vehicle application exactly for proper fitment on Ford Explorer, Explorer Sport Trac, Mountaineer, F-250 Super Duty, and F-350 Super Duty models.

Quality Assurance

Dorman OE FIX parts are engineered as direct replacements for specific factory failure points, allowing repair of the connector rather than replacement of the entire assembly.
