A smog repair station (or you) will need to trace your Saturn's EVAP leak
and determine where the leak is at. Maybe something as simple as a new clamp
or hose (part of the EVAP system) is all that's needed, or the problem may
be more severe requiring the EVAP canister or purge solenoid be replaced.
The first step is to find out where the leak is at.
Although EVAP systems vary they all contain one similar component. This
component is the Charcoal Canister. The canister is responsible for storing
gasoline vapors from the vehicle's fuel tank/s and carburetor float bowl (if
applicable) until the engine is ready to burn them through the combustion
process.
Your Saturn's charcoal canister is located either on the left or right front
corner of the engine compartment. It is a black container filled with
charcoal pellets that absorb fuel vapors. The number one fault which causes
vehicle's to fail the EVAP test is broken, loose or disconnected EVAP fuel
lines. It is necessary to trace the entire EVAP system in order to find the
defective section and/or component.
