ACDelco 85572069 Evaporative Emission Canister Assembly

The ACDelco 85572069 is a genuine GM evaporative emission canister assembly designed to capture and store fuel vapors from the fuel tank. This OE-quality vapor canister is a critical component of the vehicle's evaporative emission control (EVAP) system, helping to prevent harmful fuel vapors from escaping into the atmosphere while maintaining proper emissions compliance.

Key Features:

• Genuine GM OE part manufactured to strict factory specifications
• Charcoal-filled canister effectively absorbs and stores fuel vapors
• Direct-fit replacement for specific GM vehicle applications
• Includes integrated mounting provisions for secure installation
• Designed to work seamlessly with factory EVAP vent solenoid valves and purge systems
• Meets all federal emissions requirements and standards

This evaporative emission canister assembly is commonly used on Chevrolet Silverado and GMC Sierra models with 6.6L V8 engines (2020-2024). The canister mounts on top of the fuel tank and connects to the EVAP system hoses and vent solenoid. When fuel vapors build up in the tank, they travel through vapor lines into the canister where activated charcoal absorbs and stores them until the engine control module signals the purge valve to route them into the engine for combustion.

Replacing a faulty vapor canister can resolve issues such as check engine lights related to EVAP system leaks, fuel odors, rough idle conditions, and failed emissions testing. Installation requires removal of the fuel tank for access to the canister mounting location.
