Evaporative Canister

Print

This system is designed to limit gasoline vapor, which normally escapes from the fuel tank and the intake manifold, from discharging into the atmosphere. Vapor absorption is accomplished through the use of the charcoal canister and stores them until they can be removed and burned in the combustion process.

  1. Disconnect the negative battery cable.
  2.  
  3. On some models remove the RH engine splash shield.
  4.  
  5. Label and disconnect the hoses from the canister.
