# Intermittent Click/Tick Noise From Engine Compartment During Cold Ambient Temp

Subject: | Intermittent Click/Tick Noise from Engine Compartment During Cold Ambient Temperatures (Replace New Canister Purge Solenoid)

Models: | 2000 - 2001 Saturn L-Series vehicles equipped with DOHC 2.2L (L-61) engines

### Condition

Some customer may comment about intermittent click/tick noise coming from engine compartment. They may also comment that noise is more noticeable during cold ambient temperatures.

### Cause

The opening and closing of EVAP canister purge solenoid creates the noise. The noise is amplified due to EVAP canister purge solenoid being mounted on the air filter housing. This allows customers to hear noise inside passenger compartment.

### Correction

Replace and relocate new EVAP canister purge solenoid. Refer to procedure in this bulletin to replace and relocate new EVAP canister purge solenoid.

### Procedure
