Installation Notes and Tips

Verify the vehicle year, model, and cooler line routing before installation. This assembly uses 3/4 in. male fittings at both ends and is intended for the torque converter cooler to transmission position on the listed Ram applications. Compare the original line length and bend profile to confirm proper fit before removal of the existing hose.

For best results, inspect nearby brackets, grommets, heat shields, bushings, and sleeves on the vehicle and replace any worn components as needed during service. Proper routing and secure connection at both ends help maintain transmission fluid cooling performance.
