However, if you're determined to do it yourself, understand this comes with significant risk. Here's a *general* outline, but remember this is NOT a comprehensive guide, and professional installation is highly recommended:
1. Preparation:
* Safety First: Wear safety glasses, gloves, and long sleeves. Have a helper available to assist.
* Gather Tools: You'll need a windshield removal tool (typically a suction cup or wire cutting tool), a razor blade or scraper, a sealant removal tool (if necessary), a new windshield with proper sealant, a sealant gun, a clean shop rag, and possibly a small pry bar.
* Vehicle Preparation: Park the vehicle on a level surface. Remove any objects from the dashboard and cowl area that might interfere. Disconnect the battery's negative terminal.
* Old Windshield Removal: Carefully remove the old windshield wipers and trim. Use the windshield removal tool to carefully cut the old sealant around the perimeter of the windshield. Be gentle to avoid scratching the vehicle's paint. Slowly work the windshield out, avoiding sudden movements which could lead to injury from broken glass.
2. Cleaning:
* Thoroughly clean the frame where the windshield will sit. Remove all old sealant, dust, dirt, and debris. Use a solvent to prepare the surfaces for the new sealant.
3. Installation:
* Applying Sealant: Apply a continuous bead of urethane sealant to the windshield frame, following the manufacturer's instructions precisely. The amount and placement are critical.
* Positioning the New Windshield: Carefully lower the new windshield into the frame, ensuring it's properly seated.
* Securing the Windshield: You may need to temporarily secure it with clamps or weights to hold it in place while the sealant cures.
* Curing: Allow the sealant to cure completely, according to the manufacturer's instructions (this typically takes several hours, sometimes overnight). Do not drive the vehicle until the sealant has fully cured.
4. Finishing:
* Once the sealant has cured, remove any excess sealant.
* Reinstall the wipers, trim, and any other removed parts.
* Reconnect the battery.
Why you should hire a professional:
* Safety: Broken glass is a serious hazard. Professionals have the training and equipment to handle this safely.
* Proper Sealant Application: Improper sealant application can lead to leaks and premature windshield failure.
* Tools and Expertise: Professionals have the right tools and experience to ensure a proper and secure installation.
* Warranty: Most auto glass replacement comes with a warranty, providing peace of mind.
The cost of professional installation is generally far less than the potential costs associated with a botched DIY job, including damage to the vehicle and personal injury. Contact a reputable auto glass repair shop for a quote and professional installation. This is the safest and most reliable method.
