I recently replaced my intake manifold on my 2012 Chevy Cruze. It’s a bit of a task, but with the right tools, it’s manageable! You’ll need a torque wrench, socket set, and gasket scraper. I’d estimate about 4-6 hours for the job.

Great advice, Julie! I also recommend having rags handy to catch any spilled coolant. It can get messy!

Make sure you take photos of each step while disassembling. It saves time when you’re putting everything back together. Trust me; I’ve made a few mistakes in the past!

True! Another common pitfall is forgetting to replace all vacuum hoses. They can get brittle and break when you’re reassembly.

Absolutely! Double-check that all connections are secure. It can cause a vacuum leak that’s a pain to troubleshoot later. Has anyone else experienced issues with bolt alignment?

Good point, Tmoore! The bolts can be tricky because they’re tightened to specific torque specs. I used a torque wrench and followed the manufacturer’s sequence. It really helped!

Just be mindful of the coolant temperature when working on this. If it’s too hot, it can lead to burns. I’m excited for you; it’s a satisfying project!

Exactly! I learned that the hard way - I stripped a bolt once. Always check your tools before starting!

10

You can also add a bit of grease to the gasket to help it seal better. Just a thin layer! But don’t overdo it. Any thoughts on the best time to do this job?

11

I’d recommend a weekend—start early on Saturday. You want plenty of daylight and time to troubleshoot any issues without feeling rushed.

12

Weekend vibes! You could even treat yourself to some pizza during the process. Makes it more enjoyable, right? Any recommendations for good tools?

13

For sure! Brands like Craftsman or GearWrench are reliable. You won’t regret investing a little in good tools!

14

Remember, it’s not just about the tools. A good mindset is vital, too! Take breaks when needed. Sometimes, stepping away gives you clarity on what to do next.

Well said, Regina! Just don’t take too long of a break, or you might end up binge-watching shows instead of finishing the job! What’s your favorite project snack, everyone?

Upgrading the intake manifold on a 2012 Chevy Cruze can definitely boost performance. I installed an aftermarket manifold and noticed a gain in horsepower. It’s a great mod for optimizing air intake! Definitely worth considering.

17

That sounds promising, Jeremy! Did you notice any changes in torque as well? I’d love to know more about specific brands you recommend.

18

I’ve been looking into the gains too. From what I’ve read, some intakes can improve throttle response significantly. Anyone tried the AEM intake manifold? What’s the consensus?

19

I haven’t tried the AEM yet, but I heard great things about it. My buddy upgraded his manifold and said it made a big difference, especially in the mid-range power.

It’s important to pair the intake manifold with a good tune. Otherwise, you might not get the full benefits. I did that when I upgraded mine, and it made a noticeable impact!
