Here's a step-by-step guide:
1. Park the car in a safe location and apply the parking brake.
2. Open the hood of the car.
3. Locate the crankshaft bolt. It is located at the front of the engine, near the bottom of the cylinder head.
4. Place the correct size wrench on the bolt and turn it counterclockwise. You may need to use a breaker bar or cheater pipe to break the bolt loose.
5. Once the bolt is loose, remove it by hand.
6. Remove the pulley by prying it off with a pry bar or slide hammer.
Be careful not to drop the pulley onto your foot or any other body parts.
That's it! You have successfully loosened the crankshaft bolt and removed the pulley from your 740 Volvo 1991.
