What do i need to do to swap the head on my 2.3 QUAD4? I need to know what all needs to be done to prep for the swap. Also i need some opinons. I want to get rid of my A/C and i was thinking just bypass it with a smaller belt or i could get the GM eliminator pulley. anyone got any advice or experience?

It is a pain in the ass, easier to pull it out of the car IMO. But you have to take all the exterior drive stuff off (alt/ac/tensioner/PS pump etc). Then the intake and exhaust manis, then the bitch part, take off the timing chain housing cover and disconnect the cams and chain and tensioner then the timing chain housing, then the cam towers and then the head. PITA job on the quad motors but can be done.

It really is easier to pull the motor...the inch or so between the wheel well and the timing housing makes things difficult. The haynes manual gives enough info to do the work, just look up the info on a head gasket change. The towers will be pretty easy to understand.
if it was a 2.4, it is stupid easy and takes about 2 hours off and 2 hours on. But as stated it is not.

Once you did a few it's easy. The ONLY part that is hard is the bottom bolt that hold the water pump to the timming housing.
In order to do it easy:
1- Take off the radiator fan
2- Take off the intake manifold (13mm and 15mm bolts) (7 + 2 for the support if you have it)
3- Take off the alternator, Ac compressor and holder. (10mm, 13mm and 15mm bolts)
4- Take off the PS pump
5- Take off the exhaust manifold (13mm and 15mm bolts)(7 + the support)
6- Take off the crank pulley
7- Take off the water pump (feed tube(2), pump to block bolts(2) and pump to timming housing bolts(3))
8- Unbolt the timming cover (10mm nuts) (21)
9- Unbolt the timming chain tensionner(2)
10- Unbolt the cam gear
11- Take off the crank gear
12- Unbolt the timming housing to cam housing bolts(4 each cam)
13- Unbolt the timming housing to block bolts(7 IIRC)
14- Unbolt the timming housing to oil pan bolts(4)
15- Take off the timming housing
16- Unbolt the intake cam housing bolts(12)
17- Take off the intake cam housing
18- Unbolt the exhaust cam housing bolts(10)
19- Take off the cam exhaust cam housing
20- Unbolt the head(10)
21- Take off the head and watch out for the dowel
That should be it.
Easy job. If it's your first, plan at least 15hours if you take your time. I can take if off in about 4 hours.

why is it on the 2.3 you have to remove the intake and exhaust manifolds? GM manual said you are supposed to for the 2.4 aswell, but you don't have to.

He's swapping the head so he still has to take them off. Also, when you replace the HG, you sheck the head for flatness so having the manifolds off make it easier. Plus, it's easier to pull the head with no manifold. It's lighter.

dowel pin. It's like a guide to keep everything straight. On the cam housing and cam cover, you have 2 dowel to align the cover and the housing on the head. The block has 2 to align the head and keep the gasket in place when you put everything back together.
Do you need a torque wrench? First thing that you need to get before starting that project.
