How To Install A New Genesis Windscreen
A cracked or damaged windscreen is more than a visibility inconvenience. It compromises the structural integrity of the vehicle cabin and affects the performance of safety systems mounted behind the glass.
At Lakeland Genesis, our new Genesis models incorporate advanced driver assistance technology directly into the windscreen assembly, making proper replacement a highly technical procedure. Knowing what is involved in installing a new Genesis windscreen helps set accurate expectations.It underscores why this job belongs in professional hands.
What Makes It Complex To Install A New Genesis Windscreen
Genesis vehicles are not equipped with basic glass. The windscreen on most current Genesis models integrates rain sensors, forward-facing cameras, heads-up display projection zones, acoustic dampening layers, and in some cases, heating elements within the glass itself.
Replacing this assembly requires OEM-specification glass that matches all integrated features of the original unit. Using non-OEM or incompatible glass risks degraded sensor performance, distorted heads-up display imagery, and potential failure of camera-based safety systems. This includes Forward Collision-Avoidance Assist and Lane Keeping Assist.
Step 1: Preparation and Old Glass Removal
The process begins with protecting the vehicle's interior and exterior surfaces surrounding the windscreen opening. Wiper arms, the cowl panel, interior trim around the A-pillars, and the rearview mirror assembly are removed to provide unobstructed access.
A professional technician uses a cold knife, oscillating tool, or piano wire cutting system to carefully cut through the existing urethane adhesive. This helps bond the glass to the pinch weld flange. Controlled removal prevents damage to the flange, which must remain clean and structurally sound to properly accept the new glass.
Step 2: Pinch Weld Preparation
Once the old glass is removed, the pinch weld surface requires thorough preparation. Residual adhesive is trimmed back to a consistent base layer using a razor scraper. Any rust, corrosion, or primer damage on the flange is treated and refinished before the new adhesive is applied.
Pinch weld condition directly affects the watertight integrity and structural bond of the new installation. A compromised flange can cause leaks, wind noise, and adhesion failure that may not become apparent until weeks after installation is complete.
Step 3: Primer Application and Adhesive Bead
The glass edge and pinch-weld surfaces are treated with the appropriate glass primer and body primer in the sequence specified by the adhesive manufacturer. The primer application must be performed within the working time window before the urethane adhesive is applied.
A consistent, uninterrupted bead of OEM-approved urethane adhesive is applied around the perimeter of the pinch weld. Bead profile, height, and continuity are key. Gaps or irregularities in the bead create potential leak paths and reduce the bonding surface available to secure the glass.
Step 4: Glass Placement, Curing, and ADAS Recalibration
The new windscreen is positioned carefully and pressed firmly into the adhesive bead. Alignment is confirmed against the pinch weld flange and body gaps before the adhesive begins to cure. The vehicle must remain stationary throughout the minimum safe drive-away time specified by the adhesive product used.
Once the adhesive has cured, the forward-facing camera and any integrated sensors require professional recalibration using manufacturer-approved diagnostic equipment. Skipping this step leaves critical safety systems operating outside their designed parameters.
