What It Helps Solve

Installation Notes and Tips

Confirm the vehicle’s upper radiator-to-transmission routing and match the male quick disconnect ends before installation. Inspect the mating connections, seals, and surrounding cooler line routing for wear or contamination before connecting the new hose. Verify that the line is routed without kinks or contact points that could affect fluid flow or durability.
