I'm installing a 2.2 in a 2003 Oldsmobile Alero and I'd like to know the torque specs on the Exhaust bolts and studs. Thanks

Really need to know what? That search his normally the torque that the engine produces on the road.

Are you asking for the head torque specs? You must have new head bolts to do this, they are what you call "torque to yield" head bolts, they stretch and act like a spring, so they are one time use.. Also need to know which engine you have?

Water pump is driven by timing chain idler and is mounted on the rear of the timing chain housing. Disconnect the neg. battery cable. Drain cooling system. Disconnect oxygen sensor connector.
Remove upper exhaust manifould heat sheild. Remove exhaust manifold brace. Remove lower exhaust manifold heat sheild. Loosen manifold to exhaust manifold spring loaded nuts. Remove radiator outlet pipe to water pump coverbolts. Disconnect exhaust pipe from manifold.
Pull down on the exhaust pipe to disconnect it from exhaust manifold bolts. Disconnect outlet pipe from oil pan and transaxle. If equipped with manual tranaxle, remove exhaust maifold brace. Leave lower radiator hose attached and pull down on radiator out look pipe to disengauge from water pump. Leave outlet pipe hanging.
Lower vehicle. Remove exhaustmanifold to cylinder head nuts. Remove exhaust manifold to cylinder head nuts. Remove manifould. Remove timing chain front cover. Remove timing chain tensioner. Remove bolts bolts securing water pump cover to cylinder block. Remove water pump to timing chain housing nuts. Remove water pump attaching nuts. Remove water pump and cover assembly. Separate componets as necessary.
WHEN INSTALLING WATER PUMP MAKE SURE YOU FOLLOW THE TIGHTENING SEQUENCES THAT AFFECT SEALING. My frist one I messed up and broke the pump so becarful.
Installation
If cover was separated from body during removal, join this componets with a new gasket and hand tighten bolts. Apply bearing grease to splines of water pump drive. Set body and assemble into position.
Install and hand tighten bolts securing cover to cylinder block. Install and hand tighten bolts securing cover to cylinder block. Installand hand tighten nuts securing body to timing chain housing. Lubracate outlet pipe "O" ring with antifreeze. (I use RTV) Connect outlet pipe. Install and hand tighten bolts. Tighten bolts and nuts to specification in the following sequence. I'll ad the torque spec. at the end but this is where if you tighten out of order something will break.
pump assembly to timing chain housing nuts.
pump cover to pump body bolts
pump cover to cylinder block bolts (Bottom Bolt First)
outlet pipe to cover bolts
To complete installation reverse removel procedure.
Torque specs are 19 in. or 26mm all except water pump cover bolts which are 124 in or 14Nm
I never torque the bolts just make sure there done in the right order.

HEAD TORQUE SPEC IS 37 FT LBS ROTATE AN ADDITIONAL 90 DEGREES 1/4 TURN.

3.4L Engine To Remove:

1. Remove the lower intake manifold.
2. Remove the exhaust crossover pipe.
3. If removing the right cylinder head, remove the catalytic converter from exhaust manifold.
4. If removing the left cylinder head, remove the engine oil dipstick and tube.
5. Remove the rocker arms and pushrods.
6. Remove and discard the cylinder head bolts.
7. Remove the cylinder head.
8. Clean the mating surfaces on the following items:
   • Cylinder head
   • Cylinder block
   • Intake manifold
9. Clean the cylinder block bolt threads.

NOTE: During disassembly, keep the valve train components together for proper location during assembly.
To Install:
NOTE: Coat the cylinder head bolt threads using thread sealer.

1. If removed, install the following components:
   • Exhaust manifold
   • Accessory studs
   • Spark plugs
2. Place the cylinder head gasket in position over the dowel pins. Ensure that the THIS SIDE UP note is showing.
3. Install the cylinder head. Cylinder head torque sequence ’99-‘00
   
   Cylinder head torque sequence ’01-05
   
   
4. Install the new cylinder head bolts.
   • Tighten the cylinder head bolts a first pass to 44 ft lb (60 Nm).
5. Tighten the cylinder head bolts in sequence an additional 95 degrees.
6. Install the intake gasket.
7. Install the pushrods and rocker arms.
8. Raise and support the vehicle.
9. Install the catalytic converter and dipstick tube and indicator if removed.
10. Lower the vehicle.
11. Install the exhaust crossover pipe.
12. Install the intake manifolds.
13. Connect negative battery cable.
14. Fill the cooling system.

14 ft/lbs first pass on all then an additional 30 degrees for all on final pass ..by the way 1 bolt flat to the next bolt flat is 60 degrees so all nuts get half a bolt flat final torque if ya wanna throw caution to the wind torque it to 16 ft lbs and be done with it. lol these specs are from gm ok. good luck and ps the intake pushrods are shorter than the exhaust pushrods and there is no clearance if you get them in wrong an apprentice found this out 3 years ago and a lot of people saw what happens lol..good luck
