Well I've had my 2.4 intake manifold on since april 2009, but this is a how to i did today because i cleaned my bay out and did basic tune up stuff so i figured i'd throw something together since its a common swap and i havent found any how-to's on it. so hope its good


TOOLS NEEDED:[LIST]

• Flathead or 8mm
• 10mm socket and ratchet
• Laquer Thinner or Mineral Spirits(optional)
• Couple of rags

It's this easy.




First: You will need to disconnect the Negative Terminal on the battery.
Then start by taking the hose clamps off from the intake as circled below
the one on the right, is underneath.

-you will need a flathead or 8mm socket.




then take the intake box off


Second: you will need to disconnect the Idle Air Control. (circled in red)
then,
you will need to take the throttle body bolts off 4x 10mm (circled in green)
after that,
you will need to disconnect the evap and the brake booster (also circled in red)

(disregard the random dots haha)




Third: You will need to take the manifold bolts out of the cylinder head. (10mm socket and ratchet)

circled here in red


This is what it'll look like once you get that out of the way.



At this point in time, i recommend that VERY CAREFULLY, taking a little bit of laquer thinner or mineral spirits and clean the cylinder head surface and the surface of the manifold of any debris because you dont want anything creating a vaccum leak on the surface.

If bought used from another member, junkyard, or however you acquire it, take the gaskets out of clean them really well, like i said be careful not to get debris in the manifold itself. If bought new from CrateEngineDepot or some other source you probably will not have to clean the gaskets and what not.




Fourth: while you got everything off you mise well clean your throttle body out from all the carbon and crap built up.

Now on my TB you'll see a metal plate, from what ive been reading, theres apparently an air leak thats created if you use the 2.2 tb w/ the 2.4 manifold so you'll need the spacer that CrateEngineDepot provides.

heres the link :
Ecotec 2.2MMGF Spacer Plate Kit 2.2Plate - Crate Engine Depot



I ran it without the plate for a couple months, so youlll be ok if you dont have it right away.



Fifth: Once you got everythiing cleaned it's time to go back together!

-Make sure all gaskets are cleaned and seated correctly.
-connect EVAP
-connect Brake Booster
-connect IAT sensor
-and connect any other like things that were attached to the manifold.

Sixth: Put the throttle body back on, if you dont know the torque specs (like me, somebody help me out) dont crank the bolts to tight, just enough to tighten and wont rattle loose.

Once you got your TB back on, connect your IAC (Idle Air Control)

Last: Put Your airbox back on, and make sure to connect your Negative Terminal on your battery back up! Once you start your car back up, let it sit there and idle for a minute or two and let everything compensate. Then Enjoy!


Anything i left out or opinions let me know!

thats not the 2.2 LAP motor its the L61

TommyP

fixed. It was in the LAP section so that's what I marked it as. Should be the same swap either way.

Now with the swap I was told you'll need a tune for your car to run correctly. Is this true

Depends on your definition of correctly. On cobalts you don't need a tune for the mani swap but I'm told its a good idea.

im not tuned. been running the manifold since april 2010, no problems. you only need a tune if you run the 2.4 tb with it. also tuning makes any cobalt run better.

like blue cobalt said you only need the tune if you get the 2.4tb but if you can just get both at once and get the tune

The torque specs on all the bolts (throttle body to intake mani, and intake mani to cylinder head) are 89 in. lbs. And as for that spacer plate, I've been running my stock throttle body on my 2.4 mani for a little over 6 months with no issues at all. Also the tune is only necessary if you run the 2.4 throttle body. The car will run perfectly fine with no tune with the 2.4 mani, the tune just optimizes performance. You will most likely throw a code if running the 2.4 tb without a tune though

hey guys im buying a 2.4 manifold, my car is a 2007 2.2L and the selling is saying that I dont need an adapter plate its just bolt on and go, with some more vacuum line being the only thing needed, is this correct?
