This is a *general overview* and does not substitute for a detailed repair manual specific to your vehicle's engine (2.2L or possibly a different engine). Always consult a repair manual for precise instructions and torque specifications.
Steps involved (highly summarized):
1. Preparation: Disconnect the battery, drain the coolant, and drain the engine oil. Remove any components obstructing access to the cylinder head, including belts, hoses, wiring harnesses, intake manifold, etc. This is labor-intensive and varies significantly depending on the exact engine.
2. Cylinder Head Removal: Remove the valve cover, rocker arms, and camshaft(s). Loosen and remove the cylinder head bolts in a specific sequence (consult your repair manual). This sequence is crucial to avoid warping the head. Carefully lift the cylinder head off, taking care not to damage the head gasket or any components.
3. Inspect for Damage: Thoroughly inspect the cylinder head, block, and head gasket for any damage such as cracks, warpage, or scoring. Have the cylinder head resurfaced if necessary.
4. Clean the Surfaces: Clean the mating surfaces of the cylinder head and engine block meticulously. Any debris can prevent a proper seal.
5. Install the New Head Gasket: Carefully install the new head gasket, ensuring it's correctly aligned.
6. Install the Cylinder Head: Carefully lower the cylinder head onto the engine block, ensuring it's properly seated. Install the cylinder head bolts in the correct sequence and tighten them to the manufacturer's specified torque using a torque wrench. This step is critical for preventing leaks and warpage.
7. Reassembly: Reinstall all components removed in step 1, including the intake manifold, belts, hoses, and wiring harnesses. Reconnect the battery.
8. Refill Fluids: Refill the engine with oil and coolant.
9. Testing: Start the engine and carefully check for leaks. Monitor the coolant temperature and oil pressure.
Crucial Considerations:
* Torque Specifications: Incorrect torque on the cylinder head bolts can lead to a blown head gasket or cracked cylinder head. Use a torque wrench and follow the manufacturer's specifications exactly.
* Repair Manual: A repair manual specific to your 2001 Chevy Cavalier's engine is absolutely essential. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Special Tools: You will likely need special tools, including a torque wrench, socket set, and possibly a cylinder head bolt tightening sequence tool.
* Professional Help: This is a complex repair that requires significant mechanical skill and knowledge. If you are not comfortable performing this repair, it's strongly recommended to take your vehicle to a qualified mechanic. The cost of a repair done incorrectly can far exceed the cost of professional service.
This is a *very* simplified outline. The actual process is far more intricate and requires specialized knowledge and tools. Do not attempt this repair unless you have the necessary experience and resources. Improper repair can cause significant engine damage.
