Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Confirm lower heater hose placement on the vehicle and check that the rear heater circuit note does not apply to your configuration. Inspect adjoining fittings and clamps for wear before installing the new hose.

Quality Assurance
