Need to know how to install a crank shaft positon senson on a 2003 hyundai sonata with a 2.4 engin

Watch the video of the replacement job 2004 Hyundai Sonata Optima V6 2 7 crankshaft position sensor location and...

Really need more information...It sounds like they didn't give you a complete gasket kit...You will have to remove and re-install other components just to be able to see the crank shaft....You need the front and rear oil seal for the crank..,Oil pan gasket..,exhaust will have to be removed also...etc.......NEED MORE INFO..

It can be but it is a bear to do and you will need a full complement of tools & maybe someones' help.

Vehicles Covered: Hyundai Sonata 2002-2004 (2.4L & 2.7L Engines)

In 2003, Hyundai produced two types of Sonata:
Available engines:
4 Cylinders 2.4L VIN "S", MFI DOHC - see Figures 1 and 3.
6 Cylinders 2.7L VIN "H", MFI DOHC - see Figures 2 and 3.

To differentiate between these types of 2003 Hyundai Sonatas, the VIN 8th digit (Engine Type) will either be "S" or "H" as in the table above.

To locate the Engine drive belt, jack up the vehicle & place it onto jack stands, then slide under the car (toss a cardboard mat down first), then, once under the car, remove the (plastic) engine splash shield. Once removed, the drive & accessory belts are easily observed.

The "COMPRESSOR" refers to the A/C compressor, and "GENERATOR" refers to the Alternator.

Inspection - Drivebelt and Accessory Belts

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. Worn or damaged drive belts should be replaced.

Drivebelt Removal & Installation - 2003 Sonata (2.4L and 2.7L engines)

Raise and support the vehicle.
Remove the engine splash shield.
Rotate the drive belt tensioner clockwise to release the drive belt tension.
Remove the drive belt from the alternator.
Slowly release the drive belt tensioner.
Remove the drive belt from the accessory drive pulleys.

To install:

Install the drive belt to the accessory drive pulley.
Rotate the drive belt tensioner clockwise.
Install the drive belt to the alternator.
Ensure the drive belt is properly aligned and seated into the grooves of the accessory drive pulleys.
Slowly release the drive belt tensioner
Install the engine splash shield.
Lower the vehicle.

Here's the best illustration I can find of the Hyundai 2.4L and 2.7L engines - the drivebelt seems to be located on the passenger side of both of these transversely mounted engines.

3 to 1 ratio on oil pump/balance shaft. Pointer will have a natural fall to where its suppose to be if done right. If not excessive vibration around 2500rpm.

Possible. It's hard to give you an accurate cause, since I'm not able
to hear the sound. Most of the time, when you hear a slight wrapping
sound, it's a rod bearing,or crank bearing. When the rod bearing goes,
you'll know it,since it will knock like an SOB.

No not related, the battery and alternator can be related, but not the crank sensor.They are not on the same cicuit, just coincidence.

There are Two Balance Shafts on the 2.4. Did your mechanic also change the balance shaft belt when he changed the timing belt? If he didn't, you'll want to do that. Since you mentioned the old belt was missing teeth, those loose teeth flying around could have damaged the crank position sensor and sensor blade (tone wheel). Also, the front balance shaft (on the side of the engine nearest the radiator), has THREE different positions when the timing mark is lined up - here's the glitch - ONLY ONE of them is the correct one - this is probably where your vibration is.

I have the same problem, starting today. i was driving and it just died. and when its cold it cranks. but when hot itll start and instantly die.
