Where's the Purge Valve Solenoid on My Silverado?

I’ve been having some issues with my Silverado’s EVAP system lately, and I think it might be related to the purge valve solenoid. I’ve done some reading, but I’m still unsure about where exactly to find it on my model.

Here’s what I know:

  • Symptoms: I’ve noticed some rough idling and a check engine light popping up.
  • Model Year: 2015 Chevrolet Silverado 1500. I’ve heard that the location can vary by year, so I’m looking for info specific to mine.

What I’m looking for:

  • Location: Can someone provide the exact location of the purge valve solenoid? Is it easy to access?
  • Replacement Tips: If anyone’s replaced it before, any tips on the procedure?
  • Tools Needed: What tools will I need for this task?

Additional Thoughts:

I’ve watched a couple of YouTube videos, but sometimes it’s hard to tell exactly where things are from those angles. It would be great to get some photos or diagrams if anyone has them.

I appreciate any help you can offer!

Hey! The purge valve solenoid is typically located on the engine’s intake manifold near the throttle body. Depending on the model year, it can vary a bit, but that’s a good starting point. Hope this helps!

That’s right! For 2007-2013 models, it’s often found on the driver’s side of the engine. Just a couple of clips to remove, and you’ll see it!

I found mine on my 2019 Silverado just behind the intake. Definitely a tight fit, but you can get to it without taking the whole thing apart. Use a good flashlight!

Great tip about the flashlight! It really makes a difference when you’re working in those cramped spaces.

Just to add, some Silverado models might have a different placement. If you have a specific year in mind, I could help more!

For a 2015, yes! It’s generally in the same spot as the 2019 model. Just make sure to disconnect the battery first before you start tinkering.

I have a 2015. Should I be looking for it in the same places mentioned?

Great advice! Disconnecting the battery is a must – don’t want any nasty surprises!

LOL, nasty surprises! Like a rogue wrench flying out at you? Honestly, just be cautious. It’s a pretty straightforward job otherwise.

11

I’ve seen some people say the valve can be on the passenger side for some models. Anyone else heard this?

12

It’s rare, but I’ve seen it on later models. Always best to double-check your manual for exact specs!

Good point! I think I should look at the manual first. But it’s always handy to get real-world input like this!

14

Absolutely! Manuals have these details that can save you time… and frustration.

15

Honestly, you guys make me want to join in the DIY life! I’ve often taken the vehicle to the shop, but maybe I should give it a shot myself!

You totally should! With the right tips from this thread, you’ll feel like a pro in no time. Just remember to keep a snack nearby. :wink:

Hey everyone! I’m having issues with my Silverado. Any common symptoms for a failing purge valve solenoid? I want to make sure I diagnose it correctly.

For starters, look out for rough idling or stalling. Those can be signs that the purge valve is malfunctioning. You might also notice a check engine light.

I have experience with that! When my purge valve solenoid went bad, my fuel economy dropped significantly. It’s worth investigating if you’re facing that issue.

Exactly! Another symptom is a strong fuel smell, especially after filling up. If you notice that, definitely check your purge valve.
