REMOVAL & INSTALLATION
The charcoal filter for the evaporative emission control (EEC) system is located in the top of the air cleaner housing. It should be checked as indicated.
- Unfasten the clips and remove the top of the air cleaner case.
- Inspect the air cleaner element and clean it as necessary.
- Check the condition of the PCV valve as outlined above.
The evaporative canister is located under the hood in the engine compartment and is designed to store fuel vapors and prevent their escaping into the atmosphere. On early models, when the engine is not running, fuel that has evaporated into the condenser tank is returned to the fuel tank as the ambient temperatures rise and the vapors are condensed. Later models do not have a condenser tank. During periods when the engine is running, fuel vapor that has not condensed in the condenser tank moves to the carbon canister. The stored vapors are removed by fresh air through the bottom of the inlet hole and passed through the air cleaner to the combustion chamber. Because of the design of the system, the only maintenance associated with the canister is to replace it periodically as indicated in the Maintenance Interval charts.
