If you have decided you want to replace the timing belt on your car or light truck, it may be the right time to also do a crankshaft pulley removal. This engine component (crankshaft pulley) serves 3 purposes: as the harmonic balancer, to turns the serpentine belt and to  reduces crankshaft resonance from the car's engine. To successfully remove the crankshaft pulley in your car, follow the easy instructions below.

Step 1 – Locate Your Car's Crankshaft Pulley

Find the location of your car's pulley in your car's engine compartment. Typically, it will in the left (driver) side of the engine compartment. If you can see the car's timing belt, either on the right or left side of the compartment, you'll find the pulley close by.

Step 2 – Prepare to Remove Your Car's Wheel

With your lug wrench, loosen the lug nuts on your car's wheel that you'll need to remove. You'll need to do this before you raise your car's wheel off the floor, otherwise the wheel will likely turn when you put pressure on the wrench. Apply your parking brake and place your car's transmission lever into the "park" position. Use your car jack to raise your car's wheel, place your jack stand under the car's frame near the wheel you'll be removing. Then, lower the car so it is resting on the jack stand where it will be more safe and secure.

Step 3 – Remove the Wheel and Splash Guard

Remove the wheel's lug nuts and wheel where you'll be working.. Next, you need to remove the splash guard that's attached in the wheel well. Place the tip of a large flathead screwdriver between the splash guard and its rivets and put pressure on the screwdriver handle to remove the rivets from the splash guard. Then, remove the splash guard.

Step 4 – Remove the Crankshaft Pulley Bolt

Check your air compressor to be sure it is charged. If it isn't, turn it on and wait until it's charged.before you continue.. Then, begin removing the crankshaft pulley. You'll find it positioned behind the place in your wheel well where the splash guard was attached. Use your crankshaft bolt remover tool to back out the crankshaft bolt. To remove the bolt, position the bolt remover tool over the bolt head. You'll find the bolt in the pulley's center. Position the socket end over the bolt remover tool and loosen the bolt with the impact wrench. Be patient with this removal. Remember that the bolt will need an unusually large amount of torque to turn it.

Step 5 – Remove the Crankshaft Pulley

Position the crankshaft pulley removal tool arms over the pulley. Then, using the bolts that came with the tool, begin tightening the tool. Continue tightening until the pulley is released from the crankshaft.
