GM Genuine Parts 12690512 Vapor Canister Purge Valve — for Ecotec Engines (2.0L / 2.5L / 2.7L / 3.6L)

A check engine light with EVAP-related codes (P0441, P0443, P0446, P0455), a strong fuel smell from the engine bay, rough idling, or reduced fuel economy — these are common signs that your vapor canister purge valve is failing. The purge valve controls the flow of fuel vapors from the charcoal canister to the engine intake manifold, where they are burned. A faulty valve can cause EVAP system leaks, poor performance, and increased emissions. Replacing it with this genuine GM part restores proper EVAP function and protects your vehicle's emissions system.

This is a factory-original GM vapor canister purge valve (OE part number 12690512), designed for GM's Ecotec engine family. It is engineered with a precise solenoid and internal spring mechanism to open and close at the correct times, maintaining optimal fuel vapor flow during engine operation. This is the same part sold at GM dealerships and used on the factory assembly line.

FAQ

FAQ

Is this a genuine GM part or a copy?
This is 100% genuine GM / ACDelco OEM — in original factory packaging with GM part number printed on the label. It is not an aftermarket brand or a replica.

Does this fit my 2018 Chevrolet Equinox with the 2.0L turbo engine?
Yes — the 2018 Equinox with the 2.0L Ecotec engine uses this purge valve. We recommend verifying with your VIN.

Does this fit the 3.6L V6 engine?
Yes — this valve is also used on the 3.6L Ecotec V6 in Traverse, Camaro, XT5, and other models. Please verify your application.

Can I install this myself?
Yes — it is a simple plug-and-play replacement. However, we recommend consulting your vehicle’s service manual for the correct installation procedure and any required reset after installation.

How do I test this valve?
You can test the valve with a multimeter to check the solenoid resistance, or use a scan tool to actuate the valve and listen for the clicking sound. Refer to your service manual for the correct resistance values.

Will this fit my 2015 Chevrolet Colorado?
Yes — the 2015 Colorado with the 2.5L or 3.6L Ecotec engine uses this purge valve. Please verify with your VIN.

Does this valve come with a gasket or seal?
No — this valve does not require a gasket. It seals against the intake manifold with an O-ring that is pre-installed on the valve.

What is the torque spec for installation?
The typical torque spec is 8–10 Nm. Do not overtighten — the plastic housing can crack.

Can I use this valve for the vent solenoid?
No — this is the purge valve, which is different from the vent solenoid. The vent solenoid is located near the canister and has a different function and part number.

Is this valve compatible with other GM vehicles?
This valve is used on many GM models with Ecotec engines. However, always verify your specific application by VIN before ordering.
