GM Cutlass RWD 1970-1987 Repair Guide

Evaporative Emissions Control System

Print

This system, standard since 1970, eliminates the release of unburned fuel vapors into the atmosphere. The only periodic maintenance required is an occasional check of the system lines kinks or other damage and deterioration. Lines should only be replaced with quality fuel line or special hose marked EVAP. If equipped with a replaceable filter, it should be replaced every 24 months/30,000 miles (48,270 km). The filter is found in the bottom of the carbon canister, which is located in the engine compartment and should be removed and replaced.
