How to Replace Car Windscreens

Summary

A small chip in your car windscreen can quickly turn into a large crack, necessitating a full replacement. This detailed guide will help you replace your car windscreen yourself, covering everything from measuring the windscreen to applying the new sealant. Follow these steps to ensure a proper fit and avoid common pitfalls.

Why Replace Your Windscreen?

A small chip or crack in your windscreen can quickly spread, compromising the structural integrity of your vehicle and obstructing your view. According to the National Highway Traffic Safety Administration (NHTSA), windscreen damage is a leading cause of vehicle accidents. Therefore, timely replacement is crucial for your safety.

Tools and Materials Needed

Before you start, gather the following tools and materials:

• Tape measure
• Suction cups
• Windscreen removal tool (resembles a bent knife)
• New windscreen
• Sealant (in a caulking gun)

Step-by-Step Guide

1. Measure and Purchase the Windscreen

First, determine the year, make, and model of your car. Use a tape measure to get the exact dimensions of the windscreen. This will save you multiple trips to the store. Prices can vary significantly, so shop around for the best deal.

2. Secure the New Windscreen

Once you have your new windscreen, place it in a secure spot to avoid any damage. Use large suction cups to handle the windscreen safely. Attach the first suction cup in the middle and the second one about 8-12 inches apart.

3. Remove the Old Windscreen

Use the windscreen removal tool to cut through the sealant holding the old windscreen in place. Insert the tool at one of the corners and pull it straight down along the sides and across the top. This process will require both hands and some effort.

4. Clean the Frame

After removing the old windscreen, clean up any remaining glass and dried sealant. Use the same tool to scrape off the old sealant, being careful not to damage the frame.

5. Apply New Sealant

Load the new sealant into a caulking gun and apply it evenly around the frame. Avoid large blobs; aim for a consistent line of sealant.

6. Install the New Windscreen

Attach the suction cups to the new windscreen and carefully place it into the frame. Press firmly around the edges to ensure a good seal, but be cautious not to apply too much pressure.

7. Check for Proper Installation

If installed correctly, the windscreen should be secure with no gaps. Test it by checking for leaks during rain or listening for air rushing in while driving.
