1. Preparation is Key:
* Gather your tools: You'll need a variety of tools, including:
* Rubber mallet or plastic deadblow mallet
* Putty knife (various sizes)
* Channel-lock pliers
* Utility knife
* Razor blades
* Automotive adhesive remover (e.g., 3M adhesive remover)
* Clean rags and shop towels
* Safety glasses
* Gloves
* New rear window (ensure it's the correct year and model)
* New weatherstripping (likely needed)
* Urethane automotive adhesive (specific type recommended for automotive glass)
* Caulking gun
* Measuring tape
* Possibly a window installation tool (helps with alignment and even pressure)
* Remove the old window:
* Carefully remove the interior trim around the rear window.
* Use a putty knife and adhesive remover to loosen the old adhesive holding the window in place. Work slowly and carefully to avoid damaging the body.
* Once the adhesive is loosened, gently remove the window. It may be helpful to have a helper to support the weight.
* Thoroughly clean the window channel of all old adhesive, paint chips, and debris. This is crucial for a proper seal.
* Inspect the window channel: Check for rust, damage, or deformation in the window channel. Repair any issues before installing the new window.
2. Installing the New Window:
* Prepare the new window: If necessary, apply new weatherstripping to the edges of the new window, following the manufacturer's instructions.
* Apply adhesive: Apply a bead of automotive urethane adhesive to the window channel, following the manufacturer's instructions carefully. The amount and placement are critical for a proper seal.
* Install the window: Carefully position the new window into the channel, ensuring it's properly aligned. Use a window installation tool (if you have one) to help with even pressure and alignment. Gently but firmly press the window into place.
* Secure the window: Allow the adhesive to cure completely according to the manufacturer's instructions (usually several hours or overnight). Do not disturb the window during this time.
3. Final Steps:
* Clean up excess adhesive: Once the adhesive is cured, carefully remove any excess adhesive that squeezed out.
* Reinstall interior trim: Reinstall the interior trim around the rear window.
* Inspect the seal: Check for any leaks or gaps.
Important Considerations:
* Safety: Wear safety glasses and gloves throughout the entire process. Broken glass is a hazard.
* Adhesive: Use the correct type of automotive urethane adhesive specifically designed for automotive glass.
* Patience: This is a meticulous process. Take your time and work carefully to avoid mistakes.
* Professional help: If you're uncomfortable with any aspect of this process, seek professional help from an experienced auto glass installer. A poorly installed rear window can lead to leaks and other problems.
