Service and repair of windshields need equipment such as hot air guns as well as pneumatic knives with offset blades and interior auto glass cut-out knife kits. Start your procedure by disconnecting the battery ground cable when outdoor temperatures fall below 10°C while preparing the Polyurethane (PU) adhesive with heating by placing cartridges on a warm radiator or applying a hot air gun at 25°C for 15 minutes. Begin by removing the cowl panel weather strip from the vehicle then detach its windshield wipers by lifting the arm covers, taking out wiper nuts, washers, and arms followed by cowl grille panel removal before taking off the windshield side and top weather strips along with A-pillar trim and sun visor screws and clip and detach the front of the headliner with a small block as a spacer. Use the pneumatic knife on the windshield with a 28 mm hooked blade and finish the cutting process by using a 60 mm hook blade on the bottom edge. Following this, cut the preliminary adhesive with a round-edged blade from an auto glass cut-out knife. Cutter blades on an interior auto glass cut-out knife should be used to cut through PU adhesive on top and sides while applying EC7784 lubricant or soap water solution (10:1 ratio). You should operate the cutter blade near the connectors during installation of a heated windshield. An auto glass cut-out knife with an eight-inch cutter blade installed on the cutting edge allows you to proceed with the bottom edge cut assisted by another technician who will extract the windshield using suction pads. Before applying the bodywork seal, eliminate excess PU adhesive from the opening while retaining about 1 mm substance at the bodywork's surface. Inspect the pinch weld area for any damage or foreign materials. Correct procedures require warm airflow to eliminate moisture inside the windshield opening as well as the glass bond line before processing the glass and windshield opening and trimmed PU adhesive following adhesive kit protocols. A continuous bead of PU adhesive should be applied 8-10 mm high to the windshield flange where breaks need 20 mm overlap and the initial 100 mm section should be discarded for improved working time. Controlling personnel can help mount the windshield using suction pads while warm air should be applied continuously for 15 minutes when the temperature is below 10°C. The maintenance process requires reinstalling the rear view mirror and headliner and its spacer then the sun visor clip and screws followed by A-pillar trim panels and windshield top and side weather strips and cowl grille panel as well as windshield wipers before reconnecting the battery ground cable.
