Evap Canister Charcoal Canister 911-095 for Chevy GMC - Reliable EVAP

In this review the focus is practical: the 911-095 Evap Canister Charcoal Canister is for owners of Chevy Silverado, GMC Savana and Sierra models (and certain Workhorse chassis) who need a direct replacement to clear EVAP codes or restore fuel system venting. The bottom line is that this part fits the intended 2004-2020 applications and solves common evaporative emission faults without fuss; customers report straightforward installation and restored functionality, making it a solid choice for DIY mechanics and repair shops dealing with persistent EVAP check engine lights.

Key Features

• Wide vehicle compatibility: Fits 2004-2020 Chevy Silverado, GMC Savana and Sierra models and select 2004-2005 Workhorse FasTrack chassis so one part covers many common trucks.
• OEM cross-references: Listed with OEM numbers such as 12569373 and 15137021 so buyers can match it to original equipment part lists with confidence.
• Direct replacement design: The canister is built to replace failed charcoal canisters and vent solenoids, restoring proper evaporative emissions control without major vehicle modification.
• Code-clearing functionality: Reported by customers to resolve EVAP codes and even turn off the check engine light when the canister and solenoid were the root cause.
• Simple installation: Many users found the unit easy to install, saving time and shop labor compared with more complex repairs.
• Maintenance support: Backed by a 180 day maintenance service window for short-term coverage after installation.

Who It's For

The canister is aimed at owners and technicians working on Chevy Silverado 1500/2500/3500 (including HD Classic and Express variants), GMC Savana and Sierra models from roughly 2004 through 2020 who have EVAP system faults or evaporative emissions leaks. It is a practical replacement when OEM part numbers like 12569373 or 15137021 are referenced in diagnostic trouble codes or parts lookups.

It is less appropriate for vehicles outside the listed model years or for drivers seeking a universal aftermarket performance upgrade; if a vehicle has unrelated fuel system damage or other emission control failures, additional diagnosis is required before replacing the canister.
