With a helper on the outside, pull the piano wire (A) back and forth in a sawing motion. Hold the piano wire as close to the rear window (B) as possible to prevent damage to the body, and carefully cut through the adhesive (C) around the entire rear window. Cutting positions: Carefully remove the rear window.

With a putty knife, scrape the old adhesive smooth to a thickness of about 2 mm (0.08 in.) on the bonding surface around the entire rear window opening flange: Do not scrape down to the painted surface of the body; damaged paint will interfere with proper bonding. Remove the fasteners from the body. Clean the body bonding surface with a sponge dampened in alcohol. After cleaning, keep oil, grease and water from getting on the surface. If the old rear window is to be reinstalled, use a putty knife to scrape off all of the old adhesive, the mouldings, and the fasteners from the rear window. Clean the inside face and the edge of the rear window with alcohol where new adhesive is to be applied. Make sure the bonding surface is kept free of water, oil and grease.
