How to Replace a Windshield

Although replacing a windshield may seem like a difficult undertaking, it is possible to complete it successfully with the correct equipment, planning, and patience. Everything you need to know about How to replace a windshield will be covered in this post, including where to buy a replacement, how many people are needed, what tools are needed, and a thorough step-by-step tutorial.

Tools Needed to Replace a Windshield

Here’s a list of tools and materials you’ll need for the job:

1. Replacement windshield (specific to your vehicle’s make, model, and year).
2. Windshield adhesive (urethane-based, often provided with replacement kits).
3. Primer (for preparing the frame).
4. Caulking gun (for applying the adhesive).
5. Windshield removal tool (like a cold knife or wire saw).
6. Suction cups with handles (for safely handling the glass).
7. Gloves (to protect your hands and maintain a clean surface).
8. Safety glasses (to protect your eyes).
9. Plastic scraper (to remove old adhesive).
10. Cleaning supplies: microfiber cloth, glass cleaner, and rubbing alcohol.
11. Masking tape (to hold the windshield in place temporarily).

Replacing a windshield is a two-person job. Handling the glass safely and aligning it correctly requires precision and care, which is difficult to achieve alone.

Where to Buy a Windshield

• Auto Parts Stores: Local or chain auto parts stores often stock windshields for popular vehicles.
• Online Retailers: Websites like AutoZone, Amazon, or specialized windshield retailers allow you to order the exact windshield you need.
• Dealerships: Although more expensive, dealerships ensure you get an OEM (Original Equipment Manufacturer) windshield.
• Salvage Yards: If you’re on a budget, salvage yards can provide used windshields in good condition.

Ensure the windshield matches your car’s specifications, including dimensions, curvature, and any embedded features like heating elements or sensors.

Step-by-Step Guide to Replace a Windshield

1. Preparation

• Park in a safe, dry, and level location: Ideally, work in a garage or shaded area to protect against weather.
• Gather your tools: Keep everything you need within reach.
• Wear safety gear: Gloves and safety glasses are essential.

2. Remove the Old Windshield

1. Remove the wiper arms and cowl panel: Unscrew and detach any components obstructing the windshield.
2. Cut through the adhesive: Use a cold knife, wire saw, or removal tool to cut the urethane adhesive around the edges of the windshield. Work carefully to avoid damaging the vehicle frame.
3. Lift out the windshield: Using suction cups with handles, carefully remove the old windshield. This step requires two people to avoid breaking the glass.

3. Clean the Frame

1. Remove old adhesive: Use a plastic scraper to remove excess urethane from the frame.
2. Clean the surface: Wipe the frame with rubbing alcohol to remove dirt and grease.

4. Prepare the Frame and Glass

1. Apply primer: Apply a thin layer of primer to the frame and let it dry.
2. Test-fit the windshield: Place the new windshield on the frame to ensure proper alignment.

5. Apply Adhesive

1. Load adhesive into the caulking gun.
2. Apply a continuous bead of adhesive around the frame, following the manufacturer’s instructions for width and placement.

6. Install the New Windshield

1. Position the glass: Using suction cups, lower the windshield into place, ensuring it aligns correctly.
2. Press gently: Apply even pressure around the edges to secure the glass in the adhesive.
3. Use masking tape: Apply tape across the windshield to hold it in place while the adhesive cures.

7. Allow the Adhesive to Cure

• Refer to the adhesive manufacturer’s curing time, typically 24 hours. Avoid driving the vehicle during this period.

8. Reinstall Components

• Reattach the wiper arms, cowl panel, and any other removed parts.

Success tips to replace a windshield.

• Follow instructions: Carefully follow the adhesive and primer manufacturer’s guidelines for the best results.
