Installation Notes and Tips

Verify the end fittings before installation: this assembly uses a 3/8-inch ID hose end and a 16 mm long swivel O-ring end. Confirm the vehicle application and note that 1990-1995 Ford Taurus and 1994-1995 Ford Sable listings specify no cooler required. Inspect related brackets, grommets, heat shields, bushings, and sleeves during service so the replacement matches the original routing and protection points.
