Mirthcos EVAP Purge Solenoid Valve 12630282 (2M1405) - Direct-Fit for GM V6/V8, Restores Idle & Emissions

The Mirthcos 12630282 vapor canister purge solenoid valve is a direct-fit EVAP purge valve designed to replace the original part and restore proper fuel-vapor routing and emissions control on compatible GM vehicles.

If your vehicle is showing an EVAP-related check-engine light, rough idle after refueling, or reduced fuel economy, a failing purge solenoid can be the culprit. This replacement unit matches OE reference 12630282 (also referenced as 2M1405) and is engineered to fit a wide range of Chevrolet, GMC, Cadillac and Buick models from mid-2010s to early 2020s. It reinstates controlled vapor flow from the charcoal canister to the intake manifold so the engine can purge stored fuel vapors when appropriate.

How will this purge valve fit my GM vehicle?

The Mirthcos purge solenoid is designed as a direct-fit replacement for vehicles that list OE reference 12630282 / 2M1405. Fitment covers many Chevy, GMC, Cadillac and Buick engines across multiple model years—check vehicle compatibility before ordering.

• Direct-fit replacement: mounts and electrical connector match OE specifications.
• Compatible models: Camaro, Silverado, Tahoe, Suburban, Corvette, Colorado, Traverse and more.
• Engine coverage: V6, V8 and select L4 engines as listed in product specifications.
• OE reference included: 12630282 (2M1405) to simplify parts lookup.

What performance differences should I expect after installing it?

Replacing a faulty purge solenoid typically returns normal EVAP operation, which helps the engine management system run as intended. You may notice steadier idle, fewer evaporative-emission faults, and improved overall drivability if the original valve was stuck open or closed.

• Reduces EVAP-related check-engine codes when installed correctly.
• Improves idle stability after refueling events by restoring proper purge timing.
• Helps maintain expected fuel vapor routing to the intake manifold.
• Restores signal response to the vehicle’s engine control module (ECM).

How difficult is installation and what should I prepare?

Installation is straightforward for anyone comfortable with basic engine-bay work. The unit usually secures with one or two mounting points and a single electrical connector; standard hand tools are typically sufficient.

• Tools: basic hand tools (ratchet, sockets, screwdrivers) and possible trim removal tools.
• Time: many installations take 20–45 minutes depending on vehicle layout.
• Precautions: allow engine to cool, relieve fuel system pressure if needed, and confirm connector fit before starting.
• Verify: clear any stored codes after installation and confirm the check-engine light behavior.

What does this part include and how does it affect emissions control?

The Mirthcos purge solenoid comes as a complete valve assembly meant to replace the OE device. It restores controlled purging of charcoal-canister vapors to the intake, which is part of the vehicle’s evaporative-emission control (EVAP) strategy.

• Complete valve assembly engineered to match OE dimensions and connector type.
• Helps the EVAP system function correctly, reducing evaporative emissions during normal operation.
• Compatible with multiple GM evaporative systems across supported models.
• Includes OE reference number for easier cross-referencing during purchase or service.

Who is this for: The Mirthcos 12630282 purge solenoid is intended for do-it-yourselfers, independent mechanics, and fleet service shops needing a reliable OE-referenced replacement for GM vehicles that list 12630282 / 2M1405. It’s especially suitable if you’re troubleshooting EVAP codes, experiencing unstable idle after refueling, or replacing an aged, leaking, or non-responsive purge valve.
