About

This document contains product specifications, installation instructions, and troubleshooting for the E30 chassis. This user guide is intended for the BMW owner with basic mechanical skills; however, the evacuation and charging of freon should be handed by a licensed A/C professional. Assembly instructions assume the vehicle is stock and still retains all its original equipment. Always conform to basic safety standards and procedures when working with automotive chemicals, tools, and electrical equipment. If you are uncertain about your mechanical abilities during the removal or installation, please consult a certified professional mechanic.
