Remove any trim that may be around the windshield. A professional may get away without removing interior trim such as A-pillar. If you feel more comfortable removing the trim, please do so. Carefully remove any clips, fasteners, and retainers. Avoid breaking or losing them because they usually can be re-used.
Cut out the old windshield using a windshield removal tool. You can also remove a windshield with guitar string or a stiff, thin wire. The easiest and cheapest way to remove the windshield is to use an 18" Urethane Cut-Out Knife which is typically used by professionals. Cut the urethane around all the perimeter of the windscreen. As you cut out the windshield, be careful to minimize damage to the pinch weld.
Install the new windshield. Since you are recommending the windshield yourself, we would recommend that you get a second person to help you with this step. If you are planning on installing windshield by yourself it is recommended that you use heavy duty suction cups to handle the windshield. Make sure to use rubber gloves so that you don't contaminate the windshield glass or get any grease on the windshield. Place the windshield on the car and push it with the palm of your hand all around the windshield glue line. Re-install the cowling wipers, trims and mirrors that you may have removed.
