REMOVE

1. Raise vehicle on jack stands or centered on a frame contact type hoist. See Hoisting in the Lubrication and Maintenance section of this manual, for the required lifting procedure to be used for this vehicle.
2. Remove the tire and wheel assembly from the vehicle.
3. Remove the speed sensor cable routing bracket Speed Sensor Cable Routing Brackets from the steering knuckle. Remove the wiring harness sealing grommet retainer and speed sensor routing bracket from the inner fender.
4. Remove speed sensor sealing grommet from the inner fender Wheel Speed Sensor Connection To Vehicle Wiring Harness Then unplug the speed sensor cable from the vehicle wiring harness Wheel Speed Sensor Connection To Vehicle Wiring Harness
5. Remove bolt Speed Sensor Head Attachment To Steering Knuckle attaching the speed sensor head to the steering knuckle. Then remove speed sensor head from steering knuckle. CAUTION: If speed sensor head locating pin has seized to the steering knuckle, do not attempt to remove speed sensor head by grasping with pliers and turning. This will damage the speed sensor head. Use only the following procedure.
   
6. If speed sensor head can not be removed from steering knuckle by hand, the locating pin on the speed sensor head has seized to the steering knuckle do to corrosion. Remove speed sensor head from steering knuckle using the following procedure. Remove disc brake caliper from steering knuckle, and remove brake rotor from hub/bearing assembly. Then insert a pin punch through hole in front steering knuckle Speed Sensor Head Removal From Steering Knuckle and tap speed sensor head locating pin out of steering knuckle.

Drain the coolant, remove the exhaust pipe(s) from the exhaust manifolds, remove heater hoses from heads, remove, rocker covers from the heads,remove cam belt covers and cam belt, undo the head bolts, and remove heads, this is a short version of removing the heads, but I got the feeling this job might be a little big, if you don't know for sure what you doing. special if it has to go back together as well.

First drain water . remove cables from plugs and any thing attached to the head. Remove valve cover, remove valve rocker. remove manifold. undo head studs , undo from the center working one stud at a time from left to right of center. lift off head.

Drain antifreeze -DON"T POUR IT DOWN A STORM DRAIN - then remove valve cover, Remove exhaust from head assembly. On this engine the head is also the intake manifold - it's cast as a unit. Remove carb and remove heater hoses from carb base plate. Remove head bolts and discard. Break head loose from block - may have to smack it a time or two to break gasket loose. Get a buddy to help lift the head off the block - it's fairly heavy. Clean gasket surfaces on both head and block. Install new gasket onto block - pay attention to gasket orientation - it goes on only one way correctly. Reverse procedure to re-install - USE NEW HEAD BOLTS! Silly to try to save $20 bucks on bolts and ruin an engine.

6. Install the breather hose and spark plug cables from the rocker covers.
7. Install the water pipe assembly.
8. Install the water passage assembly.
9. Install the water outlet pipe and o-rings.
10. Disconnect the exhaust pipe from the manifold.

Cylinder Head Removal & Installation 3.1L Engine To Remove:
NOTE: With some minor variations, this procedure can be used on both the left and right cylinder heads.

1. Raise and safely support the vehicle.
2. Drain the engine coolant and the engine oil. Lower the vehicle.
3. Remove the upper and lower intake manifolds.
4. Remove the rocker arms and pushrods.
5. Remove the exhaust crossover pipe.
6. Remove the engine mount strut bracket.
7. If removing the left side (front) head, remove the dipstick tube.
8. Tag for identification, then remove the spark plug wires.
9. Remove the spark plugs.
10. Remove the exhaust manifold using the procedures found in this section.
11. Remove the eight cylinder head bolts, then remove the cylinder head. There are locator pins that align the head to the block. Pull upwards on the head to disengage the pins, then remove the cylinder head to a suitable work area.
12. If the head is be overhauled, remove any remaining components such as the engine lift hook, the fuel line bracket bolts, the engine coolant temperature sensor, etc., as required.

Position a new gasket, install the head, then tighten the bolts in the sequence shown (3.1L engine shown)

To Install:
NOTE: If the head gasket failed, determine the cause. Gasket failure is caused by the following conditions: improper installation; overheating due to a failure in the electric cooling fan system or a leak in the cooling system; loose or warped cylinder head; missing, off location or not fully seated locator dowel pins; low torque on the cylinder head bolts; warped block surface; scratched or gouged gasket surfaces; excessive intake manifold torque and even cracked engine block tapped holes.

1. Clean all parts well. Remove all foreign material to the bare metal. Do not use a motorized wire brush on any gasket sealing surface. It is good practice to use the proper size thread-cutting tap to clean the threaded bolt holes in the block. This helps assure an accurate torque reading.
2. Place a new head gasket on the clean engine block deck surface. Many gaskets will have some sort of marking denoting TOP or THIS SIDE UP. Make sure the gasket sits flat and is not hung up on the locator dowel pins. Use no sealer on the head gasket.
3. Carefully set the cylinder head in place, using care not to damage the gasket. Make certain that the head engages the locator dowel pins that properly position the head.
4. The bolts should be very clean since dirt built-up on the bolt threads makes it difficult to get an accurate torque reading. These are 'torque to yield' bolts which stretch a small amount when tightened; new bolts are always recommended. On a used vehicle, especially a high-mileage vehicle, it may be difficult to determine if the heads have been removed before and how many cycles the bolts have been removed and tightened. New bolts should be part of any cylinder head service. Use GM Sealer #1052080, or equivalent, on the threads of the head bolts and install all eight bolts, finger-tight.
5. With an accurate torque wrench, tighten the bolts gradually, in sequence, working from the center outwards. Final torque should be 33 ft. lbs. (45 Nm), plus an additional 90 degrees (1/4-turn). A torque angle meter is recommended.
6. Install the remaining components in the reverse order of the removal process.

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.

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.

first remove all ancillaries from round and on cylinder heads like exhaust manifolds inlet manifold airbox etc once you have done this remove tappet or cam cover inside these will be some large bolt heads set out along the heads in twos remove these and your heads are free but when you put it back together dont 4get new head gaskets and other gaskets

Cylinder head and related components


Cylinder head bolt torque sequence

To install:

1. Verify the identification marks on the cylinder head gasket. Install the gasket so that the surface of the cylinder head identification mark faces toward the cylinder head.
   
2. Install the cylinder heads with new gaskets. Do not apply sealant to these surfaces.
   
3. Tighten the bolts in sequence to 75–82 ft. lbs. (105–115 Nm).
   
4. Installation is the reverse of the removal procedure.
