How To Replace A Windshield

  1. Remove the clips ‐ The clips could be damaged and need to be checked. There are many different models, so knowing which way the clips lock in place is important.
  2. Figuring out the pinch weld ‐ This is the area at the front of the car, outside of the windshield, where the metal components join together. This is both the structure of the vehicle and the frame for the windshield. The windshield can be cut away from the pinch weld with a cold knife or a razor.
  3. Cut the urethane ‐ This is the adhesive that holds and seals the windshield.
  4. Lifting out the windshield ‐ This requires two people. Open both doors, and push on the windshield evenly from both sides. Once loose, lift levelly from the pinch weld.
  5. Clean the pinch weld ‐ Remove any dirt, and rinse with plain water. Contaminants will affect the adhesive.
  6. Trim off remaining urethane with a razor ‐ Usually the pinch weld is left with about a 1⁄4” of the old urethane, and it’s recommended that no more than 3/16”, or 3mm, remain. It is best for new urethane to be applied to the old urethane.
  7. Check the pinch weld for rust ‐ A clean, smooth base is absolutely necessary. This may require sanding down to bare metal, and priming.
  8. Install the frit band ‐ This is the black band that runs around your windshield. It has to be primed so that the frit band’s molecules open up to accept the urethane.
  9. Apply the urethane ‐ This is best done with an electric caulking gun, ensuring a uniform, even bead for best adhesion.
  10. Place the glass ‐ Align the top and bottom by eye, and set the glass on the pinch weld. Press in place.
  11. Allow the adhesive to dry ‐ This is very important. Depending on the type of adhesive, this could take one to twenty‐four hours. Always follow the manufacturer’s instructions.

If this sounds like something you’d rather not do yourself, then you should definitely contact an auto glass expert to help you.

Here’s a simple Windshield Replacement Checklist with items to follow up on and ensure your windshield replacement is done correctly.

  1. Are the technicians properly certified?
    Ask if technicians have passed the Automotive Glass Replacement Safety Standards.
  2. Will adequate adhesive be used?
    Make sure the installer uses urethane, which can hold up to 600lbs per square inch. This is also part of the AGRSS training.
  3. Does the shop offer a warranty?
    A slight oversight could lead to leaking or road noise, so with a warranty you know any errors won’t be yours to pay for.
  4. What’s the right kind of glass?
    There are two kinds: OEM and Aftermarket windshields. OEM stands for Original Equipment Manufacturer, and, as expected, that means a windshield that is made to be a perfect fit. It will also be the same thickness and durability as the original. Aftermarket auto glass is made by a glass manufacturer that doesn’t have to stick to manufacturer guidelines, and the thickness and durability may differ.
