Note: Always wear eye, hand and wrist protection while working on the vehicle. This vehicle is equipped with dual airbags and will require additional cure time before releasing vehicle to the owner. The Performance Achievement GroupLLC always recommends rapid curing two-part high viscosity urethane for passenger side airbag equipped vehicles. Inform the vehicle owner of the cure time and any other additional precautions before installation. Always return the vehicle to manufacturer’s specifications.

Be sure to protect all interior and exterior portions of the vehicle to prevent any damage.


Disconnect the wires from the mirror. Grasp the stem of the breakaway style mirror and twist the assembly away from the glass. Store the mirror in a safe location. Remove the plastic covers on the wiper arms with a small screwdriver to expose the retaining nut. Remove the nut and release the spring tension by lifting the blade to remove the wiper arm from the post. Some wipers may be difficult to remove and may require a wiper arm tool.

Remove the plastic cowl retainer on the passenger side of the cowl. Then remove the plastic push-in retainers by gently prying up on the Phillips head portion of the retainer. Remove the screws from the cowl panel and remove the one-piece cowl with the hood open. The replacement glass includes a new molding that wraps around the edge of the glass on three sides.

Starting on the bottom of either side of the vehicle, remove the molding by pulling up and away from the glass. Always be careful, especially with repainted vehicles, not to pull up any body paint during this process.

Removing the original windshield:

Before removing the existing glass, examine the new windshield for any defects, scratches, cracks, etc. If the glass is damaged at all, do not install it into the vehicle. Obtain a new, undamaged windshield. Cut the adhesive with a cold knife or power cut out tool on the top and sides of the glass. Cut the adhesive on the bottom with a power tool, as it does not follow the outside edge of the glass. Take special care and do not damage the painted surface of the pinchweld.

Preparing for the new windshield:

The Performance Achievement Group always recommends using the full cut out method. Using a sharp chisel, remove the adhesive leaving a thin skin of well-bonded urethane on the pinchweld, being careful not to disturb the body paint. Prime the pinchweld according to your adhesive manufacturer's specifications. Concentrate on any areas of the paint that may contain scratches or other damage.

Placing the new windshield:

The new glass will include a foam strip. Apply the foam strip to the bottom of the glass. With the new molding applied to the glass, dry set the windshield and mark the proper position with a wax pencil. Be careful not to contaminate the primed surfaces. Apply suction cups to the proper positions on the glass, remove the windshield from the opening and set it on the windshield stand with the outside of the glass facing down. Using a "V-notch" tip, apply the adhesive along the inside edge of the molding and directly below the reference mark (drawn during the dry set) on the bottom of the glass. Applying the adhesive to the glass will assure proper contact.

Set the windshield into the opening using the dry set marks as guides for proper placement. Once the glass contacts the pinchweld, use caution not to slide the glass. Apply slight pressure around the perimeter of the windshield.

Finishing Touches:

Use a leak detector to assure a proper seal. Replace the cowl, wipers and mirror in reverse order of removal. Clean and detail the vehicle. Return the vehicle to the owner in better condition than it was received.
