Tools you will likely need:
* Repair Manual: Absolutely essential. Provides torque specifications and precise steps.
* Timing belt kit: This usually includes the belt, tensioner pulley, and sometimes the idler pulley(s). Get a kit from a reputable parts supplier.
* Jack and jack stands: Safely support the vehicle.
* Wheel chocks: Essential for safety.
* Socket set and wrenches: Various sizes will be needed.
* Torque wrench: Crucial for tightening components to the correct specification.
* Pry bar: May be needed to help release tensioners.
* Ratchet and extensions: To reach tight spots.
* Flywheel locking tool: Necessary to prevent the crankshaft from rotating. This is critical!
* Camshaft holding tool: Helps keep the camshafts from rotating. Also critical!
* Safety glasses and gloves: Protect yourself.
General Steps (This is NOT a complete guide):
1. Safety First: Disconnect the negative battery cable. Consult your repair manual for specific safety precautions.
2. Access the Timing Belt: Remove any components obstructing access to the timing belt. This typically includes the right-front wheel, some plastic covers, and potentially other components. Your repair manual will guide you on what to remove.
3. Mark the Timing Belt and Component Positions: Before removing anything, carefully mark the position of the crankshaft pulley, camshaft sprockets, and the timing belt itself. This is crucial for proper reassembly. Use a marker to create reference points. Photos are also extremely helpful.
4. Loosen and Remove the Timing Belt Tensioner: This often involves loosening a bolt and using a special tool or pry bar to release tension on the belt. Your manual will detail the exact procedure.
5. Remove the Timing Belt: Carefully remove the old timing belt, noting its routing.
6. Inspect Components: Carefully examine the idler pulleys, tensioner pulley, and water pump for wear or damage. Replace any worn or damaged components.
7. Install the New Timing Belt: Install the new timing belt, ensuring it follows the proper routing indicated by your marks and the repair manual.
8. Install and Tighten the Timing Belt Tensioner: Install the new tensioner (if included in your kit), and tighten it to the manufacturer's specifications using your torque wrench.
9. Reinstall Components: Reassemble all the components you removed earlier, ensuring everything is correctly positioned.
10. Check Timing: Double-check that your timing marks align perfectly before starting the engine. An improperly timed engine will cause catastrophic damage.
11. Reconnect the Battery: Reconnect the negative battery cable.
12. Start the Engine: Carefully start the engine and listen for any unusual noises. Inspect for any leaks.
Disclaimer: This is a highly simplified overview. Failure to follow the precise instructions in a repair manual specific to your 2002 Chevy Cavalier 2.2L engine can result in serious engine damage. If you are not comfortable with this level of automotive repair, take your vehicle to a qualified mechanic. The cost of a professional repair is far less than the cost of engine rebuild or replacement.
