The art of replacing a windshield requires a specific set of skills and tools. While not impossible, it is not a task for the average DIYer. However, the process of removing a windshield, in preparation for a professional replacement, is much simpler and can be accomplished with basic tools and knowledge.
The first step in removing a windshield is to protect the interior of your vehicle. This is easily done by placing an old blanket or tarp over the dashboard and seats. Make sure to tuck the material under the edges of the dash to prevent glass shards from falling inside. Next, carefully remove the trim around the windshield. This trim is usually held in place by clips or screws, so use a screwdriver or trim removal tool to gently pry it loose. Once the trim is removed, you will have access to the bolts that hold the windshield in place.
Using a socket wrench, loosen the bolts one at a time. Do not remove the bolts completely just yet. Once all the bolts are loose, carefully lift the windshield from the frame. Have a helper assist you with this step, as windshields can be heavy and awkward to handle. Once the windshield is lifted, carefully place it on a flat surface where it will not be damaged. Now that the windshield is removed, you can prepare the frame for the new one. This process involves cleaning the frame of any old sealant or debris and applying a new layer of sealant around the perimeter. Once the sealant is applied, the new windshield can be carefully lifted into place and bolted down. Finally, replace the trim around the windshield and vacuum up any glass shards that may have fallen into the vehicle.
