Generally it is removed with an impact gun. If you need to do this at home, you can use an impact socket on a solid breaker bar (no swivel ends) Place the socket on the crank bolt and wedge the bar either against the ground or a solid chassis part, then with ignition disabled, bump the starter. the engine will rotate and unscrew the bolt. Be really careful if you try this. if the bar gets loose you can get hurt or damage parts of the car that are in its way.

These days I use an impact wrench and it works great but there was a time I smacked a breaker bar with a hammer or mallet while a friend held it in place, others have reported that they use a breaker bar and pipe to brace the bar against the frame and then they turn the starter over.
I have never liked nor used that method so before I had air tools I used the breaker bar and mallet, It has never failed to break the bolt loose but it takes longer.

2.0 or 2.3L: working on engines, not knowing what is there???
here is the teaser answer, no photos , no warnings, etc.

quoted in part, and remove chain only.
exploded view of first timing chain and related components-2.0L and 2.3L engines
  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Remove engine assembly from vehicle.
  3. Remove oil pan.
  4. Remove cylinder head cover.
  5. Remove timing chain cover as follows:
    • Remove crankshaft pulley bolt. To lock crankshaft pulley, use special tool 09917-68221 (camshaft pulley holder).
Be sure to use the following bolts instead of pins for fixing special tool to crankshaft pulley. Bolt size: M8, P1.25 L = 25 mm (0.98 in.) Strength: 7T

  • Remove crankshaft pulley. To remove crankshaft pulley, use special tools 09944-36011 and 09926-58010 (steering wheel remover and bearing puller attachment).
  • Remove A/C compressor bracket.
  • Remove alternator belt idler pulley, water pump pulley and alternator belt tensioner.
  • Remove timing chain cover bolts and nut.

  1. For reinstallation of timing chain, turn crankshaft so that timing marks on cylinder head and lower crankcase match with those on sprockets as shown in figure.
  2. Remove second timing chain as follows:
    • Turn crankshaft to meet following conditions.
      • Key (I) on crankshaft is positioned as shown.
      • Arrow mark on idler sprocket (II) points upward.
      • Marks on sprockets (III) match with marks on cylinder head. Note that this step must be followed for reinstallation of timing chain.
    • Remove timing chain tensioner adjuster No.2 and gasket. To remove them, slacken second timing chain by turning intake camshaft counterclockwise a little while pushing back pad.
    • Remove intake and exhaust camshaft timing sprocket bolts. To remove them, fit a spanner to hexagonal part at the center of camshaft to hold it stationary.
    • Remove camshaft timing sprockets and second timing chain.
After second timing chain is removed, never turn intake camshaft, exhaust camshaft and crankshaft independently more than such an extent as shown. If turned, interference may occur between piston and valves and valves themselves, and parts related to piston and valves may be damaged.

  1. Remove timing chain guide No.1.
  2. Remove timing chain tensioner adjuster No.1.
  3. Remove timing chain tensioner.
  4. Remove idler sprocket and first timing chain.
  5. Remove crankshaft timing sprocket.

    1998-2003 To Remove:
    1. Remove or disconnect the following:
      • Crankshaft pulley and hub
      • Drive belt tensioner gm_truck_s10_tcbolts.gif

      • Timing chain cover bolts gm_truck_s10_tc.gif

      • Timing chain cover and gasket
    2. Install a bolt in the end of the crankshaft CAUTION
      Do not install the crankshaft balancer bolt or a bolt longer than 1 inch or damage to the crankshaft threaded hole will result.
    3. Rotate crankshaft until the number 1 piston is at Top Dead Center of compression stroke.
    4. Make sure that the alignment marks are aligned with the tabs on the timing chain tensioner. gm-03-22-611.gif

    5. Measure distance between hole in bracket and unworn surface of timing chain tensioner shoe. NOTE: If distance between the hole and unworn surface of timing chain tensioner is greater than 0.314 in (8 mm), replace tensioner, timing chain and sprockets.
    6. Remove timing chain tensioner bolts.
    7. Remove the timing chain, timing chain tensioner and camshaft sprocket at the same time.
    8. Remove the crankshaft sprocket using special tool J 22888-20A or equivalent.
    9. Remove crankshaft sprocket alignment key.
    gm-03-22-612.gif

    NOTE: If any camshaft components are being replaced to correct a noise problem, all camshaft drive components must be replaced.
    To Install:
    1. Install the crankshaft sprocket alignment key.
    2. Install the crankshaft sprocket using special tool J 5590 or equivalent. gm-03-22-613.gif

    3. Compress the timing chain tensioner spring and insert a pin into the tensioner hole to retain the tensioner shoe.
    4. Install timing chain and timing chain tensioner (do not tighten tension bolts).
    5. Align the crankshaft and camshaft timing marks with the tab on the timing chain tensioner.
    6. Tighten the timing chain tensioner bolts.
      • Torque to: 18 ft lbs (24 Nm)
    7. Tighten the camshaft sprocket bolt.
      • Torque to: 96 ft lbs (130 Nm)
    8. Remove pin from timing chain tensioner hole.
    9. Remove bolt from end of crankshaft. CAUTION
      Inspect the timing chain cover for warping or damage. Replace if needed.
    10. Clean all timing chain cover mating surfaces.
    11. Install or connect the following:
      • Timing chain cover to the engine block
        1. Ensure that the gasket is installed properly in the groove in the timing chain cover
      • Timing chain cover and make sure it fully seated on the alignment dowel pins
      • Timing chain cover bolts
        1. Torque to: 97 inch lbs (11 Nm)
      • Drive belt tensioner
      • Crankshaft damper hub and the crankshaft pulley

    I have broken the timing chain guide rail while removing my cylinder head. Now I do not know how to remove the lower timing cover. Thanks, Jamie


    not familiar with a benz but it should be much the same as most other cars.
    usually the crankshaft pulley needs to be removed from the crank as the timing cover is behind it
    once the pulley is removed you should only have to remove the bolts that hold the cover to the block and gently pry it loose and remove it
    hope this has helped you

    Timing chain is loose how do I replace or tighten


    You need to pull out the timing cover. 4-6 hours of work. Here is the step to remove the Cover, then you need to remove the Sprockets.
    moz-screenshot.pngmoz-screenshot-1.png
    1. Remove the oil pan.
    2. Remove the power steering belt if so equipped.
    3. Remove the air conditioning belt, compressor and bracket if so equipped.
    4. Remove the fan clutch (fluid coupling), with the fan and water pump pulley.
    5. Matchmark and remove the crankshaft pulley(s). This bolt will be very tight. Use the counter-holding bar, properly installed, to hold the crankshaft while loosening the bolt. Use the pulley extractor or gear puller to remove the pulley from the shaft.
    6. Remove the water bypass pipe.
    7. Remove the fan belt adjusting bar. If necessary, remove the lower power steering bracket for access.
    8. Disconnect the heater water outlet pipe.
    9. Unbolt the timing chain cover assembly. Be careful to loosen only the correct bolts.

    To install:
    1. Install new gaskets over the dowels on the timing chain cover. Slide the cover assembly over the dowels and pump spline. Insert the retaining bolts and tighten them. Tighten the 8mm bolts to 9 ft. lbs. (13 Nm) and the 10mm bolts to 29 ft. lbs. (39 Nm).
    2. Temporarily install the adjusting bar to the alternator. Install the adjusting bar to the chain cover and tighten the bolts to 9 ft. lbs. (13 Nm).
    3. Install the heater water outlet pipe.
    4. Install the water bypass pipe.
    5. Install the crankshaft pulley and bolt. Use the counter-holding tool to hold the pulley and tighten the bolt to 116 ft. lbs. (157 Nm). If equipped with air conditioning, install the second crankshaft pulley.
    6. Install the water pump pulley and fluid coupling with the fan.
    7. Adjust the tension on the drive belts.
    8. Install the air conditioning compressor bracket, compressor and belt if they were removed.
    9. Install the power steering belt and adjust it.
    10. Attach the oil pan.
    11. Install the radiator.
