How to Install New Windshield Glass

Installing new windshield glass is necessary if your car windshield has been cracked or shattered. A damaged windshield is not only an eyesore, it's also a visual impairment that can compromise the safety of the driver and the passengers. According to AutoMedia.Com, windshield cracks which obstruct vision are illegal in many states and can result in the driver receiving a citation. Carsdirect.com cautions that windshields should only be installed by individuals with experience in glass installation because windshields are important devices that can cause serious injury if not installed properly.

Instructions

Preparation

1

Slide a trim remover, which is a tool resembling a screwdriver and a pry bar, gently across the black trim area of the windshield until you locate the clip that holds the windshield in place. Hold the trim in place with the trim remover and use a utility knife to carefully cut the first layer of trim. Once the first layer is removed, cut away the second layer in the same manner.

2

Lift the windshield wipers from the wiper arms to remove them, then gently scrape the adhesive material from under the windshield using a chisel.

3

Pull the windshield forward using a plastic windshield stick, then remove all clips from the windshield. Allow the windshield to rest in the opening.

4

Place suction brackets on the windshield to protect the windshield from shattering, and carefully remove the windshield from the car.

Installation

5

Clean the windshield mounting surface on the car thoroughly by using a chisel and a cloth to remove any debris.

6

Apply a bead of urethane primer with a caulking gun to the windshield mounting surface.

7

Scuff the mounting surface on the new windshield using sandpaper, then apply a bead of urethane primer with a caulking gun all around the entire new windshield mounting surface.

8

Place suction brackets on the new windshield and carefully lift the windshield onto the car. Slide the new windshield carefully into the windshield mounting surface, applying gentle pressure to adhere the new windshield to the urethane primer.

9

Check that there are no gaps between the windshield and mounting surface, then remove any excess primer using a cloth.

10

Press the trim back into place over the new windshield using your hands or a rubber mallet, then reattach the windshield wipers to the wiper arms.

11

Apply flow-grade butyl sealant to the new windshield and cover the area with masking tape. Clean the new windshield thoroughly using glass cleaner and a cloth.

Wait several hours until the sealant cures before removing the masking tape or driving the car.
