Alfa GTV & 916 Spider - Full headlight lens cleaning guide

Tools needed:
  • Large bladed chisel (or large flat blade screwdriver, but undesirable)
  • Star screwdriver (for removing engine bay cowling)
  • Microfiber cloth
  • Water (or weak cleaning solution)
  • Retracting blade (for cutting caulking)
  • Gloves and eye protection in case you chip the glass (or else you’ll end up like me )
Pre-work: Leave front of car to warm up in the sun, softening the caulking

Steps:

  1. Remove engine bay cowling by unfastening screws in 4 locations (circled)
  2. Remove 3 lens clips located around the lens (circled), using a large bladed chisel
  3. Remove and discard any dirty caulking (coloured black), using a large bladed chisel. Be cautious not to scuff the light housing (grey).
  4. Use large bladed chisel to prise the lens away from the housing. This needs to be done at the top of the lens (not on the clip area): insert chisel at union of lens top and housing (shown in picture); then apply slow progressive force until the glass starts to move. Don't try and force the whole glass off in one go - the caulk is similar to Blu-Tack and needs to have time to stretch.
  5. Cut the clean caulking (whitewith retracting blade (or something similar)
  6. Remove entire lens, or leave bottom caulking attached and hinge down (like I have done)
  7. Clean the inside of the lens with a microfiber cloth and water (or weak cleaning solution). Heed caution in cleaning the reflectors (evengentle cleaning may remove some silvering)
  8. Replace the lens onto the housing amidst clean caulking, ensure that caulking is redistributed if required
  9. Attach lens clips to lens (easier if you work from back to front, from housing first then pressure onto lens clip area)
  10. Reattach engine bay cowling
  11. Compare before/after difference and increase smugness by 10 points
