I've been hearing what I thought was noisy injectors, coming from my engine bay for a while now. I was finally determined to figure out why my Cruze was so much louder than the rest. Found it to be the Evap purge solenoid, mounted to the intake maniold. Once the car is warmed up, and the valve is "purging", it repetitively clicks, many times a second, almost synchronous with the firing pulses of the engine. Unplug the wire connector, and it stops. Anybody else ever have this issue? A new AC Delco part is only $20. May replace it and see what happens.

Mine is doing the same thing and so I bought a new one too, although it was $50 at Autozone. After I install it I'll let you know if the clicking is gone. One way I determined the click is not the engine is that the clicking does not change frequency with engine RPMs. Then I listened with the hood opened and grabbed the purge valve solenoid in my hand and could feel the click right there.

Definitely report back on that! I've had the same loud clicking for about 20k now (I've got 75k on my '13 ECO). It happens after the car warms up and I just chalked it up to overly noisy injectors. Hasn't hurt my mileage or anything, so I stopped worrying about it. If I can fix it for $20 I'm all over it!

Swapped mine out for a factory replacement this afternoon ($43 including tax) and the noise is gone. My old solenoid started making noise around 50k and I'll gladly pay $40 to keep it quiet. It was getting damned loud!

Glad to hear. Genuine AC Delco is $18.25 from RockAuto, if anyone else is interested. Going order one and will report back as well.

Finally got around to installing a new Delco purge valve. That fixed the problem. No more clicking.

What is the GM P/N on the replacement, and / or a link to the part on rockauto?

Are you guys replacing the valve or the whole assembly? I got the following part [h=1]ACDelco 214-2317

But I am not sure how to replace it. Those platic pipes are stiff as ****. Should I get the whole assembly here? Or is the purge valve part the one causing us issues?


Thank you!

The OP and the last post are a bit long in the tooth. You may be better off starting your own thread somewhere in the Gen I powertrain sub-forum
