Sunroof Installation on a BMW 525

Preparation
1. Enter the front seat of your BMW. Use a sharp blade to cut a hole in the headliner between the two front seats. Keep cutting until you have made a square hole with the support rod of the roof in the middle.
2. Use a metal saw to cut the support rod away from the roof of your BMW. Discard the rod in the trash. Use a file to smooth out the rough edges left by the removed rod.
3. Use a measuring tape to determine the very center of the clear are left by the removed support rod. Put on your pair of goggles and protective gloves. Once you have found the center, use a drill to drill a hole through the headliner and the roof.
4. Take the sunroof template out of the sunroof installation kit and place it on the roof of your BMW. Line up the template so that the hole drilled in the roof is at the very center of the template. Use the chalk to draw out the template on to your roof to highlight the area you need to remove for the sunroof.
5. Place the metal shears in to the hole in the roof and make the hole bigger. Cut from the hole up to the beginning of the chalk outline. Cut around the chalk frame to make the hole in the roof of your BMW. Remove the piece of the roof you have cut out and discard in the trash. Smooth out the edges of the hole with a file.
Installation
6. Place the frame of your sunroof in to the hole in the roof of the BMW. Use a socket wrench to secure the mounting bolts which fix the frame to the roof. Apply a layer of adhesive around the frame joints for added support.
7. Enter your BMW. Place the headliner and the wind deflector on to the sunroof and fix in place by attaching the screws with a Phillips screwdriver.
8. Lift the glass panel on to the top of the sunroof. Place the clamps you get in your installation kit around the glass and tighten with a socket wrench to secure the glass on to the sunroof.
9. Turn the crank on your sunroof to open and then close the roof. Repeat the process a few times to ensure that the sunroof is installed and working correctly.
