Inspect the hose, fitting and clamp seating area before assembly. Position the band on the correct hose seating surface and orient the screw housing for the clearance required by the service manual. Tighten as specified without cutting or distorting the hose.
Parts Desk Insight
Clamp selection follows the hose’s outside diameter at the fitting. Hose inside diameter alone does not determine the correct clamp.
