Installation Notes and Tips

Verify the vehicle’s year, make, model, and hose routing before installation. This hose is listed for engine-to-valve and tee-to-engine positions, with fitment notes that include applications with A/C and without auxiliary heater on many vans. Some listings note cut-to-fit usage, so compare the original hose path, end sizes, and centerline length before final installation. Gates 19750 should be matched to the exact application shown in the fitment data.
