I assume you mean the engine crankshaft harmonic damper?
It isn't unusual for a car to be fitted with a variety of harmonic dampers - on the driveline or suspension for instance.

The short answer is I don't know as I am not familiar with your model but most types are very similar to each other. Most are combined with the crankshaft auxilliary belt pulley and most can be divided into two main types - one is an assembly retained by a largish centre bolt that is usually very tight and the other is in two parts, the centre hub is retained on the crank by the aforementioned large bolt and the outer pulley/damper is retained to the hub by a number of smaller bolts.

In all cases it is necessary to remove the auxilliary belt and lock the crankshaft. A few engines have the crankshaft timing belt pulley in assembly with the pulley/damper and in that case the timing belt will also need removing.
This will be obvious by examining the replacement damper.

Those that are an assembly are generally a sliding fit on the crankshaft and should be removed by hand or some gentle leverage after the retaining bolt has been removed, though often some rust has crept in making it much tighter and it might be necessary to use a little heat, some impacts or even a gear puller or similar.

you have to take off crankshaft pulley.

TENSIONER PULLEY IS SMALL PULLEY NEXT TO CRANKSHAFT.YOU NEED A WRENCH TO ROTATE TENSIONER PULLEY CENTER BOLT TO REMOVE BELT TENSION.

The CPS for these motors is located in the front of the engine and the the timing belt cover needs to be removed to gain access. If you need further instructions on removal as well as diagrams, email me at [email protected] and I will send those immediately.

Hyundai Car 1999-05 - Removal & Installation

3.5L Engine

Remove or disconnect the following:

1. Negative battery cable
   

• Engine coolant
  
• Water pump pulley bolts
  
• Alternator bolt, loosen only
  
• Water pump pulley and drive belts
  
• Crankshaft pulley
  
• Timing belt cover(s)
  

1. Turn the crankshaft until the timing marks on the camshaft sprocket and cylinder head are aligned.
   
2. Loosen the timing belt tensioner bolt and turn the tensioner counterclockwise as far as it will go. Tighten the adjusting bolt.
   
3. Mark the timing belt with an arrow showing direction of rotation.
   
4. Remove the timing belt.
   
5. If defective, remove the timing belt tensioner.
   

Timing belt sprocket alignment mark positioning for belt removal and installation—3.5L engine

To install:

1. If necessary, install the timing belt tensioner.
   
2. Attach the top of the tensioner spring on the engine coolant pump pin. Ensure the hook on the pin is facing down and the hook on the tensioner is facing away from the engine
   
3. Rotate the timing belt tensioner to the extreme counterclockwise position. Temporarily lock the tensioner in place.
   
4. Align the timing marks of the camshaft and crankshaft sprockets.
   
5. Install the timing belt on the crankshaft sprocket, then onto the rear camshaft sprocket.
   
6. Route the belt to the coolant pump pulley, the front camshaft sprocket and the timing belt tensioner.
   
7. Apply force counterclockwise to the rear camshaft sprocket with tension on the tight side of the belt and check that timing marks are aligned.
   
8. Loosen the tensioner bolt 1–2 turns and tighten the timing belt to a tension of 57–84 lbs. (260–380 N).
   
9. Turn the crankshaft two turns clockwise.
   
10. Readjust the sprocket timing marks and tighten the tensioner bolts.
    
11. Install the timing belt covers.
    
12. Install the crankshaft pulley and tighten to 108–116 ft. lbs. (150–160 Nm).
    
13. Install or connect the following:
    
    • Timing belt cover(s)
      
    • Crankshaft pulley
      
    • A/C compressor belt
      
    • Water pump pulley
      
    • V belt
      
    • Negative battery cable
      
    • Engine with coolant
      

Removal & Installation

1. Disconnect the negative battery cable.
   
2. Disconnect the connector from the sensor.
   
3. Remove the retaining bolts.
   
4. Remove the sensor from its mounting.
   

To install:

1. Installation is the reverse of the removal procedure.
   
2. Clearance between the sensor and the sensor wheel should be 0.020–0.059 inch.
