Here's a general outline of the process. Again, this is not a substitute for a repair manual.
Tools You'll Likely Need:
* Crankshaft pulley puller: This is a specialized tool absolutely essential for this job. There are different types; ensure you get the right one for your PT Cruiser's crankshaft. Cheap pullers can break or damage the crankshaft.
* Socket wrench and sockets: To remove the bolt holding the pulley in place. This bolt is usually very tight and may require a breaker bar or impact wrench.
* Wrench: For any other retaining bolts or nuts.
* Penetrating oil (like PB Blaster): Apply generously to the crankshaft pulley bolt several hours (or even overnight) before attempting removal. This helps break loose corrosion.
* Ratcheting wrench (optional but helpful): For easier turning of the bolt.
* Torque wrench: Crucial for reinstalling the bolt to the correct specification.
* Safety Glasses: Protect your eyes from flying debris.
* Gloves: Protect your hands.
General Procedure (Consult your repair manual for specifics):
1. Disconnect the battery: This is a crucial safety step to prevent accidental short circuits.
2. Access the crankshaft pulley: This usually involves removing various components, such as the serpentine belt, belt tensioner, and potentially other accessories. Your repair manual will detail the specific steps.
3. Apply penetrating oil: Liberally spray penetrating oil onto the crankshaft pulley bolt. Allow ample time for it to soak in.
4. Remove the crankshaft pulley bolt: This is usually a very tight bolt. Use the appropriate socket and wrench, possibly a breaker bar or impact wrench. Caution: The engine may rotate unexpectedly. You might need someone to hold the engine or use a wrench on another pulley to prevent it from turning.
5. Install the crankshaft pulley puller: Carefully attach the puller according to the manufacturer's instructions. This usually involves threading the puller into the crankshaft pulley, and then applying force (carefully!) to remove the pulley from the crankshaft.
6. Remove the pulley: Once the puller is properly attached and force is applied, the pulley should come loose.
7. Inspect the pulley and crankshaft: Check for any damage to the pulley or crankshaft. Replace if necessary.
8. Reinstall (in reverse order): Reinstall the crankshaft pulley and bolt, using a torque wrench to tighten the bolt to the manufacturer's specified torque.
Important Considerations:
* Impact Wrench: While helpful, an impact wrench can easily strip the bolt if not used carefully.
* Bolt Damage: The crankshaft pulley bolt can be very difficult to remove and may be damaged in the process. Be prepared to replace it.
* Repair Manual: This is absolutely essential. The steps above are a general guideline; the specifics will vary depending on your vehicle's model and engine.
If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. This is not a beginner's job and improper technique can lead to significant engine damage.
