2020 Nissan Versa Windshield Replacement

Replacing the windshield on your 2020 Nissan Versa is a task that, while best left to professionals in many cases, can be tackled by a moderately experienced DIYer with the right tools, understanding, and patience. This guide will walk you through the process, highlighting potential pitfalls and best practices.

Safety First

Before we dive into the procedure, let’s emphasize safety. Windshield replacement involves sharp objects, potentially shattering glass, and handling adhesives that can be harmful. Always wear appropriate safety gear, including:

• Safety Glasses: Essential to protect your eyes from flying debris.
• Gloves: Heavy-duty work gloves to protect your hands from cuts.
• Long Sleeves and Pants: To minimize skin exposure.
• Respirator (Optional but Recommended): When working with urethane adhesives, a respirator can protect you from inhaling fumes.

Work in a well-ventilated area and keep children and pets away from the work zone.

Tools and Materials Required

Having the right tools is crucial for a successful windshield replacement. Here’s a list of what you’ll need:

• Windshield Removal Tool: There are several types, including:
  • Cold Knife: A handheld tool with a blade used to cut through the urethane adhesive.
  • Power Cut-Out Tool: An electric tool with oscillating blades that cuts through the adhesive much faster.
  • Wire Cut-Out Tool: Uses a wire to slice through the adhesive, often favored for its precision.
  Choosing the right tool depends on your experience and preference. A power cut-out tool is faster but requires more control. A cold knife is slower but provides more tactile feedback.
• Urethane Adhesive: Specifically designed for windshield installation. Check the expiration date! You'll want a fast-setting one-part urethane adhesive for this job.
• Urethane Primer: Crucial for proper adhesion. This prepares the pinchweld (the metal frame around the windshield opening) and the glass for the urethane.
• Glass Cleaner: To clean the new windshield before installation.
• Suction Cups: For safely lifting and positioning the windshield. Get a good quality suction cup system designed for automotive glass.
• Razor Blades or Scrapers: For cleaning the pinchweld.
• Primer Applicator (Daubers or Swabs): For applying the urethane primer.
• Caulking Gun: For applying the urethane adhesive. Use a heavy-duty gun capable of handling the viscosity of the urethane.
• Heat Gun (Optional): Can soften stubborn adhesive during removal. Be very careful not to overheat and damage the surrounding paint.
• Trim Removal Tools: Plastic pry tools to remove interior trim pieces without damage.
• Shop Rags: Lots of them, for cleaning and wiping.
• Vacuum Cleaner: To clean up any glass shards.
• Torque Wrench: For tightening any bolts or screws associated with the trim.

Removal Procedure

1. Prepare the Vehicle:
   • Cover the dashboard and seats with protective covers to prevent damage from falling glass or adhesive.
   • Disconnect the negative battery cable to prevent any electrical issues.
   • Remove the windshield wipers and any associated trim pieces. Use trim removal tools to gently pry off any retaining clips.
   • Remove any interior trim pieces around the windshield. These are typically held in place by clips or screws. Pay close attention to how they are installed so you can reassemble them correctly later.
2. Cut Out the Old Windshield:
   • Apply masking tape around the perimeter of the windshield to protect the paint.
   • Using your chosen windshield removal tool (cold knife, power cut-out tool, or wire cut-out tool), carefully cut through the urethane adhesive. Start from an upper corner and work your way around the windshield. Maintain a consistent depth to avoid scratching the pinchweld.

   Important: Work slowly and methodically. Avoid applying excessive force, which could crack the windshield or damage the surrounding metal.

   • If you encounter resistance, use a heat gun to gently soften the adhesive.
3. Remove the Windshield:
   • Once the adhesive is completely cut, carefully lift the windshield out using suction cups. Have a helper assist you to prevent dropping the glass.
   • Dispose of the old windshield properly. Most auto glass shops will accept them for recycling.
4. Prepare the Pinchweld:
   • This is a critical step for ensuring proper adhesion.
   • Remove all remaining urethane adhesive from the pinchweld using a razor blade scraper or specialized adhesive removal tool. Be careful not to scratch or gouge the metal.
   • Clean the pinchweld thoroughly with a solvent cleaner to remove any grease, dirt, or debris.
   • Inspect the pinchweld for any rust or corrosion. If present, treat it with a rust converter and primer before proceeding.
   • Apply urethane primer to the pinchweld according to the manufacturer's instructions. This primer promotes adhesion and prevents corrosion. Allow the primer to dry completely before applying the urethane adhesive.

Installation Procedure

1. Prepare the New Windshield:
   • Clean the new windshield thoroughly with glass cleaner to remove any fingerprints, dirt, or debris.
   • Apply urethane primer to the frit band (the black ceramic band around the edge of the windshield) according to the manufacturer's instructions. This primer promotes adhesion and provides UV protection.
2. Apply the Urethane Adhesive:
   • Load the urethane adhesive cartridge into your caulking gun.
   • Cut the nozzle of the cartridge at a 45-degree angle to create a bead of the desired width and height. The height and width are specified in the vehicle's repair manual, but a general guideline is a bead that is approximately 3/8" to 1/2" tall and wide.
   • Apply a consistent bead of urethane adhesive to the pinchweld, following the outline of the windshield opening. Maintain a uniform height and width throughout. Avoid creating gaps or bubbles in the adhesive.

   Tip: Practice applying the adhesive on a piece of cardboard before applying it to the pinchweld to get a feel for the caulking gun and the flow of the adhesive.

3. Install the Windshield:
   • Using suction cups, carefully lift the new windshield and position it over the pinchweld.
   • Align the windshield with the opening, ensuring that it is centered and flush with the surrounding body panels.
   • Gently press the windshield into the adhesive, applying even pressure around the perimeter.
4. Secure the Windshield:
   • Use masking tape to secure the windshield in place while the adhesive cures. Apply tape around the perimeter of the windshield to hold it firmly against the pinchweld.
   • Allow the urethane adhesive to cure completely according to the manufacturer's instructions. This typically takes several hours, depending on the temperature and humidity.
5. Reassemble Trim and Components:
   • Once the adhesive is fully cured, remove the masking tape.
   • Reinstall any interior and exterior trim pieces that were removed earlier. Ensure that all clips and screws are properly secured.
   • Reinstall the windshield wipers.
   • Reconnect the negative battery cable.

Post-Installation Checks

After the installation is complete, perform the following checks:

• Leak Test: Spray water around the perimeter of the windshield to check for leaks. If you find any leaks, apply additional urethane adhesive to seal them.
• Proper Alignment: Ensure the windshield is properly aligned with the surrounding body panels.
• Trim Security: Verify that all trim pieces are securely attached.
• Functionality: Test the windshield wipers and any other components that were affected by the installation.

Troubleshooting

Here are some common issues you might encounter and how to address them:

• Leaks: The most common issue. Ensure proper surface preparation and adhesive application are critical to prevent leaks. Reapply urethane to leaking areas if necessary.
• Wind Noise: Can indicate improper sealing. Check for gaps around the windshield and reapply urethane if needed.
• Difficult Adhesive Removal: Use a heat gun to soften the adhesive. Be careful not to overheat the surrounding paint.
• Damaged Pinchweld: Repair any rust or corrosion before applying primer and adhesive.

When to Call a Professional

While this guide provides a comprehensive overview of windshield replacement, there are situations where it’s best to call a professional:
