I want you to go to this url, it's the official KIA forum dealing with older Sorentos.https://www.kia-forums.com/2003-2010-sorento-forum/53820-sorento-crank-bolt.html It's free to create a login.
It details the need to replace the crank pulley bolt with a new one supplied by KIA. This bolt, if reused, can break causing a catastrophic engine failure. Do not buy any other bolt., it's not worth trying to save a few pennies.I have a 2005 Sorento and had my local KIA dealer do this job and other work as long as the front cover is off, replace the water pump, the timing belt idlers and tensioner assembly. It's cheaper to d all that at one time than to go back and have to redo the cover removal. Hope this helps.

Place the drain pan under the radiator drain plug, open the plug and allow it to drain. Close the plug. Loosen the four nuts on the water pump pulley but do not remove them yet. Loosen the adjusting bolts in the alternator and the power steering pump with a wrench, push them away from the belts and remove the belts.

2Remove the bolts securing the fan shroud to the radiator support using a 10 mm socket. Remove the four nuts on the water pump pulley, then remove the fan and shroud as an assembly. Remove the bolts in the crankshaft pulley using a socket. Loosen and remove the crankshaft bolt using a socket.

• 3
  

Remove the top radiator hose. Extract all the 10 mm bolts securing the top and bottom timing covers and remove the covers.

4Install the crankshaft bolt temporarily. Use a socket on the bolt and turn the crankshaft clockwise until the mark on the crankshaft sprocket aligns with the timing mark on the block at the 12 o'clock position. Look at the camshaft sprockets and make sure the left sprocket has the "I" facing straight up and the right sprocket has the "E" facing up. At the same time, notice that there is a line on each sprocket adjacent to each mark--make sure they line up with the notch on the cylinder head at 12 o'clock. This allows for perfect alignment. If they do not come close to aligning, rotate the crankshaft one more time and they will align.

5Loosen the tensioner bolt and push the tensioner away from the belt. Loosely tighten the bolt to maintain position. Remove the belt.

6Install the new belt starting on the right side away from the tensioner. Keep all the tension on the right side. Loosen the tensioner bolt and allow it to apply tension on the belt. Do not tighten the bolt yet. Rotate the engine two turns clockwise and re-align the timing marks. Tighten the tensioner bolt to 35 foot-pounds.

7Install the timing belt covers. Remove the crankshaft bolt and install the crankshaft pulley. Reinstall the bolt and tighten. Install the radiator shroud and fan as an assembly. Place the fan on the water pump pulley, install the four nuts loosely, install the bolts in the fan shroud and tighten.

8Install the belts around the crank pulley, water pump pulley and alternator and pull the alternator up to tension the belt and tighten the bolts using a socket. Tighten the water pump pulley nuts using a wrench.

9Install the belt on the power steering pump, pull the pump out to tension the belt and tighten the bolts. Install the upper radiator hose. Fill the radiator with antifreeze

Hi, Please follow below steps :

-. Jack up front wheel and remove the tires
-. Remove the Motor Mount next to the Power Steering Pump and timing belt cover

-. Loosen the Alternator/Water Pump belt.
-. Loosen the Power Steering/AC/Tensioner belt by loosening the Tensioner Bolt first.

-. Remove the power steering pump bracket. Leave the pump attached to the bracket.
-. Remove the Water Pump Pulley.

-. Now it's time to remove the Crank Pulley.

-. Remove the Timing Cover bolts.

-. Remove and replace the crankshaft sensor

Instructions Difficulty: Moderate Things You’ll Need:

• Set of ¼-inch drive sockets ¼-inch drive ratchet Set of ½-inch drive sockets ½-inch drive ratchet Set of 3/8-inch drive sockets 3/8-inch drive ratchet Set of metric wrenches Floor jack Jack stands

Step1 Raise and support the vehicle on jack stands. Remove the intake air temperature wiring, the breather hose and intake air hose. Take off the air cleaner assembly. Step2 Remove the right wheel. Remove the accessory belts. Remove the crankshaft bolt and the crankshaft pulley. Remove the power steering bolts and the timing belt covers. Temporarily install the crankshaft bolt and turn the engine clockwise until the mark on the crankshaft pulley, which is a triangle stamped into the crank sprocket, is aligned with the corresponding triangular mark on the block. Step3 Make sure that the timing marks are aligned on the camshaft sprockets. These are a line on each sprocket that runs through a tooth on each sprocket. These lines should line up in the middle between each sprocket and point toward each other. If they do not line up, turn the crankshaft one more time and they will line up. It takes two turns of the crank to one complete revolution of the cam. Step4 Loosen the water pump bolts; using the 3/8-inch ratchet, turn the water pump clockwise away from the belt and loosely tighten the bolts to keep it there. Remove the timing belt. Make sure the timing marks are aligned and install the new belt starting on the right side from the crank sprocket and working counterclockwise. Keep all the belt tension on the right side away from the tensioner. Step5 Loosen the bolts in the water pump and rotate the water pump counterclockwise to apply tension to the belt. Watch the tensioner, which is above the water pump, and apply tension with the water pump until the pointer on the tensioner lines up with the notch above it. Lightly tighten the water-pump bolts. Step6 Turn the engine two more times and align the timing marks perfectly. Loosen the water-pump bolts and, using the ratchet, apply tension to the belt until the tensioner pointers are aligned. Tighten the water-pump bolts. Step7 Install the timing-belt covers and the bolts in the power-steering pump and tighten. Remove the crankshaft bolt and install the crank pulley and the bolt, then torque the crankshaft pulley bolt to 70 foot pounds of torque. Install all components in reverse order of removal.

1. Remove the Alternator Belt.
2. Remove the Water Pump Pulley
3. Remove the Air Conditioner Belt and Power Steering Belt.
4. Remove the Crankshaft Pulley.
5. Remove the timing belt cover
6. Remove the timing belt tensioner pulley.
7. Remove the Timing Belt.
8. (If Replacing) Remove Idler Pulley.
Installation is reverse of removal. Keep a close eye on the timing marks on the cam sprockets to make sure you don't knock anything out of whack.

I would strongly recommend replacing the water pump while you are replacing the timing belt. (The water pump usually comes in the timing belt kit.) Otherwise you are going to have to do this all over again when your water pump goes out. Good Luck.
