If your car's accessories aren't working and you start hearing some knocking noise in your car's engine bay, one of the components that you'll need to check, and probably replace, would be the crankshaft pulley. Also known as a harmonic balance wheel or crankshaft sheave, it is a grooved, wheel shaped part that is connected directly to your car's crankshaft and connects all of your other accessories via serpentine belts. It also doubles as an internal dampener that decreases the vibrations caused by your car's engine, which could be harmful to certain parts inside your car.
Easy to replace, but hard to reach
Changing your car's crankshaft pulley can be a difficult task, depending on your vehicle's make and model. Some vehicles will have enough space in their engine bays that will allow you to easily take out this pulley. But for most vehicles, you might need to remove the engine itself, and this can be difficult, especially for people who do not have the time and equipment to take out a heavy engine. We strongly advise you to check your car's engine bay and see if you could take out the crankshaft pulley yourself. If you have enough working space in the engine bay, then you should definitely order a replacement and swap out the crankshaft pulley on your own. If you are unlucky enough to have a tightly spaced engine bay, then you'll either have to go to a mechanic to help you out or spend an entire day removing the engine and crankshaft pulley yourself. Don't worry, crankshaft pulleys are common car parts and shouldn't cost much, so you'll still have a little bit of cash at hand, in case you'll need to hire a mechanic to install it for you.
Save money and buy an OEM replacement
You won't go wrong when getting a compatible OEM crankshaft pulley for your vehicle, it'll be designed according to your car's exact specifications, allowing you to install them easily. The crankshaft pulley is a very basic car part with a simple design, so you won't have to worry about getting something with added features and such. Prices for most OEM crankshaft pulley replacements should hover around $100 - $250, and it should only go higher if you're getting a high-performance replacement that's designed for racing applications. If you are driving an older vehicle, we highly recommend that you also purchase replacement crankshaft pulley bolts, seals, and washers, as these could have worn out along with the pulley itself over time.
