  Q: What is the purpose of the Canister Purge Valves and Vapor Canister on Chevrolet Tracker?

  A: The evaporative emission (EVAP) system prevents hydrocarbon release into the atmosphere by storing fuel vapor from the fuel system. Components include a charcoal canister, two-way check valve, fuel cap, and connecting lines. Vapors from the gas tank are stored in the canister, which vents via a solenoid valve in carbureted or fuel-injected models. On 2001 models with the On-Board Refueling Vapor Recovery (ORVR), the canister is beneath the vehicle near the fuel tank. Inspect the canister for damages and never wash it. Test airflow in both carbureted and fuel-injected models by blowing into ports. For carbureted models, ensure the vent solenoid valve allows air when the engine is off but restricts when on. Fuel-injected models' EVAP canister purge valve should show consistent resistance and proper airflow. Replace faulty components and label hoses during replacements. Installation is the reverse of removal.

  Q: What is the function of the evaporative emissions control system and how to replace Canister?

  A: The evaporative emissions control system has the purpose of pulling in fuel vapors from the gas tank and fuel system, then storing them in a charcoal canister. Periodically inspect the charcoal canister as explained in the maintenance schedule since it works like a tank for fuel vapors. On late model fuel-injected cars with an On-Board Refueling Vapor Recovery (ORVR) system, the charcoal canister is positioned underneath the vehicle, on its right side, ahead of the fuel tank and route them to the intake manifold during normal engine operation. The most common symptom of a malfunctioning E.E.S. is that there will be strong smell of petrol coming from the engine compartment. For instance when one smells gasoline fumes, he should check for damage or wear on all hoses and charcoal canisters. The charcoal canister must be replaced at specified intervals with a new one. Remove hose connections, unbolt the bracket from either the firewall or under vehicle and disconnect hoses. Reverse procedure to install part if necessary.
