Kia Sorento Crankshafts Parts

The crankshaft of your Kia Sorento is one of the parts that rotate the engine and power the vehicle. Upgrading the crankshaft on your Sorento can make the Kias engine more powerful. To choose the right Kia Sorento crankshafts parts for your Kia Sorento, you need to know how these parts work and what types are available.

How do crankshafts work?

Crankshafts work the same in an automatic transmission vehicle and a manual transmission vehicle. The pistons in a Kias engine are connected to the crankshaft at specific points called rod journals, with every other piston being offset. As the pistons move up and down, the crankshaft turns. The relationship between the crankshaft and pistons is mutual, as the crankshaft ensures the pistons continue their movement.

Near the crankshaft is a part called a camshaft, which is connected to the crankshaft by a belt. As the crankshaft forces the pistons up and down, the belt turns, affecting the camshaft. As the belt turns, the camshaft valves open and close, allowing a mixture of air and fuel to enter the piston chamber. The turning crankshaft then forces the piston to move back up, compressing the air and fuel in the chamber. A spark causes the compressed fuel and air to combust. The force of this combustion forces the piston back down, which powers the motor. Once the fuel has combusted, the crankshaft forces the piston up once again, which, in turn, forces the exhaust from the combusted material to be forced out of an exhaust valve.

What types of crankshafts are there?

Because it is one of the most important Kia Sorento parts, you should look for a crankshaft that fits your vehicle. The main thing that differentiates crankshafts is the method used to make them. Here are the types of crankshaft parts you should consider for your Kia Sorento.

  • Cast: This style of a crankshaft is cast out of malleable iron and is made by pouring liquid iron into a sand mold. Each mold makes one half of the crankshaft. After the iron has solidified, the two halves are welded together, creating a complete crankshaft. This style of crankshaft is reliable and sturdy.
  • Forged: This style of crankshaft uses a mold similar to the cast style, but instead of pouring the liquid into the mold, the mold is pressed around a hot iron bar, compressing it into the desired form. The excess metal is manually trimmed off, leaving a solid and powerful crankshaft.
