Installation Notes and Tips
Verify the hose shape, end diameters, and centerline length against the original part before installation. Confirm vehicle configuration on Ford Courier applications, since this hose is not for AC-equipped vehicles. Inspect adjoining clamps, necks, and coolant passages for wear or corrosion before installing the Gates 20791 hose.
