WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.

- Insulator
- Expansion valve

Insulation is used around expansion valve to prevent moisture (condensation) build-up and to protect expansion valve from high engine compartment temperatures and the resulting decrease in A/C system cooling performance.

Install insulator -1- over expansion valve -2- (arrow).
Check insulator for damage and proper fit, and replace if necessary.
