Windshield installation requires a number of timed steps because of the cure times involved with
primers, solvents, and adhesives used in this procedure. This is important and must be followed.
When replacing a cracked windshield, it is important that the cause of the crack be determined and
the condition corrected, before a new glass is installed. The cause of the crack may be an
obstruction or high spot somewhere around the flange of the opening; cracking may not occur until
pressure from the high spot or obstruction becomes partially high due to winds, extremes in
temperature , or rough terrain.
