If your windshield has even a small crack, it should be replaced as soon as possible. The law requires you to replace your windshield if the crack is longer than the width of a quarter. A cracked windshield is a safety issue. Designers of the 1998 Toyota Corolla considered the strength of the windshield when calculating the overall strength and safety of the car. In a rollover accident, the car could collapse because of a windshield defect. You may have a professional replace the windshield, but you can do it yourself if you are careful and know precisely what to do.
Instructions
- 1
Inspect the windshield frame. The area around the windshield should be free of dents, cuts and corrosion. The new windshield will not fit properly into a bent frame. If this area is damaged get it repaired. You should use only an original equipment manufacturer (OEM) windshield, which you can order from a local dealer.
2Protect the car. Lay vinyl drop cloths over the hood and dashboard of your car. Windshields are made of safety glass that can shatter.
3Remove the wiper blades and arms by using a flat head screwdriver.
4Remove the rubber trim around the windshield. Insert your flat head screwdriver under the trim. Pry and pull the trim until it is completely off the car.
5Cut the silicone. Use a razor blade to cut around the edge of the windshield to free it from the silicone sealant.
6Take out the windshield. Insert your pry bar under a corner of the windshield. Gently pry the windshield up. Slowly work your way around the windshield. Have an assistant help you lift the windshield out the car.
7Prepare the windshield frame and new windshield. Sand the windshield frame. Apply a polyurethane adhesive along the mounting surface by following the manufacturer's instructions. Sand the inside edge of the new windshield. Apply polyurethane adhesive to the sanded area to ensure a tight bond.
8Caulk the window frame. Lay a bead of silicone around the window frame. Do not leave any gaps.
9Lay in the new windshield. Gently insert the new windshield, preferably with the help of an assistant. Press firmly and evenly on the new windshield. After the bonding agent has dried, insert the rubber molding by hand. Install the wiper blades and arms, and detail your work.
