Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
- Negative battery cable
- Drive belt(s)
- Power steering pump
- Alternator and bracket
- Valve rocker cover
- Positive Crankcase Ventilation (PCV) hose and spark plug wires
- Connector bracket attaching bolt
- Crankshaft Position (CKP) and Camshaft Position (CMP) sensors
- Oil pressure switch
- Knock sensor
- Blow-by hose
Relieve the fuel system pressure and disconnect the fuel pipes.
- Intake manifold and gasket
- Water pipe
- Timing belt, camshaft sprocket and related components
- Oil level gauge guide attaching bolt on the left cylinder head
- Cylinder head bolts in the proper sequence. Leave bolts 1 and 3 installed loosely to prevent the cylinder head from falling.
- Cylinder head from the block, use a plastic-faced hammer, if needed, to separate the head from the cylinder block
- Bolts 1 and 3
- Cylinder head and gasket
Clean all gasket material from both mating surfaces.
To install:

Fig. 4: Cylinder head bolt tightening sequence-2.2L engines
Inspect the cylinder head for warpage. Warpage should not exceed 0.0020 in. (0.05mm).
Install a new head gasket and the cylinder head.
Secure the head in place with the mounting bolts. Coat each bolts with clean engine oil, and hand-tighten. Tighten the cylinder head bolts, in sequence, to the following specifications:
1. Step 1: 22 ft. lbs. (29 Nm).
2. Step 2: 51 ft. lbs. (69 Nm).
3. Step 3: loosen all bolts by 180 degrees, then loosen an additional 180 degrees.
4. Step 4: bolts 1 and 2: 25 ft. lbs. (34 Nm).
5. Step 5: bolts 3, 4, 5 and 6: 11 ft. lbs. (15 Nm).
6. Step 6: all bolts plus 80-90 degrees.
7. Step 7: all bolts plus 80-90 degrees.
  NOTE: Do not exceed 180 degrees total tightening.
Install or connect the following:
- Oil level gauge guide attaching bolt on the left cylinder head
- Timing belt, camshaft sprocket and related components
- Water pipe
- Intake manifold and tighten the bolts to 21-25 ft. lbs. (28-34 Nm)
- Fuel delivery pipes
- Blow-by hose
- Knock sensor
- Oil pressure switch connector
- CKP and CMP sensors
- Connector bracket attaching bolt
- Spark plug wires
- PCV hose
- Valve rocker cover and tighten the bolts to 44 inch lbs. (5 Nm)
- Alternator
- Power steering pump
- Accessory drive belt
- Negative battery cable
Start the engine and allow it to reach operating temperature. Check for leaks.
