GM GENUINE PARTS Vapor Canister Vent Valve purge valve 12630282 — OEM fit, electrically actuated

The GM Genuine Parts 12630282 Vapor Canister Vent Valve is the original-equipment replacement that regulates fuel vapor flow from the charcoal canister to the intake for proper evaporative emissions operation.

This vapor canister vent valve (also called a purge valve) is built to General Motors’ factory specifications to match the fit, function and durability of the part installed at the factory. It’s a direct-replacement emission control component designed for GM vehicles, intended to restore correct vapor routing and maintain expected operating behavior without modification. If your vehicle’s evaporative system is showing codes or drivability symptoms related to purge control, this GM Genuine Parts valve gives you a like-for-like repair option.

How does this valve control fuel vapor flow?

The valve opens and closes under command of your vehicle’s engine control module, allowing metered amounts of fuel vapor from the charcoal canister into the intake manifold when conditions are appropriate. By regulating that flow, it helps ensure the EVAP system vents vapors only when the engine can burn them efficiently.

• Electrically actuated valve that responds to ECU signals.
• Mated to OEM connectors and vacuum ports for direct fit.
• Specifically calibrated to GM factory flow and sealing requirements.

What signs indicate the purge valve needs replacement?

Common indicators include an illuminated check engine light, ECU codes related to EVAP or purge circuit faults, or irregular idle and fuel odors when evaporative routing is compromised. Visual inspection can also reveal cracked housings or damaged electrical connectors that justify replacement.

• Diagnostic trouble codes (DTCs) tied to EVAP/purge circuits.
• Strong fuel smell from the engine bay or fuel tank area.
• Physical damage to the valve body, ports, or electrical plug.

Why choose GM Genuine Parts 12630282 instead of aftermarket options?

This GM Genuine Parts valve is manufactured to the original equipment specification, so it matches the original in fit, sealing surfaces, electrical interface and operational characteristics. Using the OEM replacement reduces the variables during diagnosis and helps preserve vehicle emission compliance and performance.

• Made to GM OE specifications for fit, form and function.
• Connector and vacuum port locations match factory routing for easier installation.
• Designed for the same service life and reliability as the original component.

How do I install and care for the purge valve?

Installation is typically straightforward: disconnect the battery, unplug the electrical connector, remove hoses, replace the old valve with the GM Genuine Parts unit, reconnect hoses and connector, then clear any related codes. Routine care is mainly visual checks during service intervals; if hoses become brittle or electrical clips corrode, replace them to maintain system integrity.

• Basic install: unplug, unclip hoses, swap valve, reattach and clear codes.
• Inspect surrounding hoses and connectors for wear and seal integrity.
• Use specified torque and routing to avoid pinched lines or loose seals.

Who is this for: Drivers, technicians and DIY enthusiasts who need a factory-spec replacement for a malfunctioning EVAP purge valve on a compatible GM vehicle. Choose this GM Genuine Parts 12630282 valve when you want an OE-fit component that reduces guesswork during repairs and helps keep your vehicle’s evaporative emission system operating as designed.
