CLICK HERE for Timing info on your vehicle.

These were probably the pics you couldnt see due to size limits on FixYa.

As long as you have not taken apart yet. Just align the marks up and use the cam tool align the crank sprokett. The Audi is that way. I think it will be # 3 that is at top dead center. As long as the marks are aligned you are fine. All the audi I have ever done even the newer ones # 1 is never at top dead center. This is not an american car that everybody is use to working on.

Thanks for using FixYa!!

What is the timing procedure for a 2003 Audi A6 Quattro 3.0


there is a special tool as there are no timing marks, in front of the cam gears are plates with two holes in each (for location of tool) there is also a tool that protrudes into the crankshaft position sensor hole.. if you dont have access to the specialty tools , than i would engrave marks on the gears and covers to align to original positions.

Timing belt timing marks


Instructions
  1. Remove the Timing Belt 3.0 V6
    • Place the Voyager's engine in the TDC no. 1 position for cylinder firing in order to get proper alignment. Disconnect the negative cable on the battery.
    • 2Take off the accessory drive belts, and take out engine mount insulator, located in the engine support bracket. Detach the engine support bracket and take off the torsional damper and crankshaft pulleys. This ensures easier access to the timing belt.

    • 3. Locate the 2- to 3-inch wide timing belt in the front of the engine. Remove the cover of the timing belt.
    • 4Mark the course of rotation on the belt as a reference if you plan to reinstall it. Slacken the timing belt torsioner bolt and take off the timing belt. Detach the timing belt torsioner if needed.
    • 5Remove the crankshaft sprocket and the flange shield of the crankshaft sprocket. Secure the camshaft sprocket using a spanner tool MB990775, or something similar, and take off the bolt and washer to the camshaft sprocket.
    Install the Timing Belt
    • 6Use the retaining washer and bolt to fit the camshaft sprocket onto the camshaft. Utilize the spanner tool MB990775 and tighten the bolt. Mount the crankshaft sprocket and put on the timing belt torsioner and tensioner spring if it was removed. Hook the higher end of the spring to the water pump pin and bottom end to the tensioner bracket with the hook facing out.
    • 7Rotate the timing belt tensioner in a counterclockwise turn and tighten the bolt to momentarily hold it in place. Turn the crankshaft sprocket until the timing mark lines up with the timing mark on the oil pump timing mark. Revolve the back camshaft sprocket so that its timing mark lines up with the generator bracket timing mark. Turn the radiator side camshaft sprocket so that the mark aligns with the inner timing belt cover mark.
    • 8Connect the timing belt onto the Voyager's crankshaft sprocket, keeping the belt tight on the side of tension. Install the belt in the same rotational direction if using the original timing belt. Put the timing belt on the radiator side of the camshaft sprocket, and place the belt underneath the water pump pulley first, and follow that by putting it over the back camshaft sprocket and the tensioner.
    • 9Create tension on the side of the timing belt and correctly line up all timing marks. Put the crankshaft sprocket flange into place and loosen the tensioner bolt to allow the tensioner spring to put tension on the belt. Turn the crankshaft two clockwise turns. Line up the timing marks and tighten the tensioner bolt. Put on the timing belt cover and engine support bracket.
    • 10Put the engine mount insulator, crankshaft pulleys and torsional damper into place. Mount the accessory drive belts, connect the negative battery cable and check that the engine runs properly.

Need diagram to replace timing belt on 2000 dodge intrepid 3.5 engine


I Show Only a 3.2L For this Year this Will Guide you Enjoy your Work RejakWilson


REMOVAL

CAUTION: The following procedure can only be used when the camshaft sprockets HAVE NOT BEEN LOOSENED or removed from the camshafts. Refer to Camshaft Gear/Sprocket and Timing Components, if sprocket(s) or camshaft(s) have been loosened or removed.

CAUTION: The 3.2/3.5L are NOT freewheeling engines. Therefore, care should be taken not to rotate the camshafts or crankshaft with the timing belt removed.

  1. Disconnect negative cable from remote jumper terminal.
  2. Remove upper radiator crossmember.
  3. Disconnect fan module electrical connector.
  4. Remove cooling fan module and accessory drive belts.
  5. Remove crankshaft damper and front timing belt covers.
  6. Mark belt running direction, if timing belt is to be reused.
CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.

f90f2f1.gif Fig. 94

  1. Rotate engine clockwise until crankshaft mark aligns with the TDC mark on oil pump housing and the camshaft sprocket timing marks are between the marks on the rear covers (Fig. 94).
CAUTION: Align the camshaft sprockets between the marks on rear belt covers before timing belt removal or damage to valve and/or pistons could occur.

  1. Using a ink or paint marker; mark the exact position of the camshaft sprocket timing mark relative to the two timing marks on the rear timing cover.
NOTE: When timing belt tensioner is removed from engine, always store in the vertical (plunger facing upward) position

09766f9.gif Fig. 95

  1. Remove the timing belt tensioner (Fig. 95) and remove timing belt.
TIMING BELT TENSIONER

  1. When tensioner is removed from the engine it is necessary to compress the plunger into the tensioner body.
CAUTION: Compress the tensioner slowly, as damage to tensioner could result.

c719a3d.gif Fig. 96

  1. Place the tensioner into a vise and SLOWLY compress the plunger (Fig. 96). Total bleed down of tensioner should take about 5 minutes.
CAUTION: Index the tensioner in the vise the same way it is installed on the engine. This is to ensure proper pin orientation when tensioner is installed on the engine.

  1. When plunger is compressed into the tensioner body install a pin through the body and plunger to retain plunger in place until tensioner is installed.
NOTE: When timing belt tensioner is removed from engine, always store in the vertical (plunger facing upward) position.

INSTALLATION

CAUTION: This procedure can only be used when the camshaft sprockets HAVE NOT BEEN LOOSENED or removed from the camshafts.

CAUTION: If camshafts have moved from the timing marks, always rotate camshaft towards the direction nearest to the timing marks (DO NOT TURN CAMSHAFTS A FULL REVOLUTION OR DAMAGE to valves and/or pistons could result).

a7cd673.gif
Fig. 97

  1. Align the crankshaft sprocket with the TDC mark on oil pump cover (Fig. 97).
  2. Align the camshaft sprockets (to reference mark made upon removal) between the marks on the rear covers (Fig. 94).
  3. Install the timing belt starting at the crankshaft sprocket going in a counterclockwise direction (Fig. 97). Install the belt around the last sprocket. Maintain tension on the belt as it is positioned around the tensioner pulley.
  4. Holding the tensioner pulley against the belt, Install the tensioner into the housing and tighten to 28 Nm (250 in. lbs.) . Each camshaft sprocket mark should still fall between the cover marks.
  5. When tensioner is in place pull retaining pin to allow the tensioner to extend to the pulley bracket.
  6. Rotate crankshaft sprocket 2 revolutions and check the timing marks on the camshafts and crankshaft. The marks should line up within their respective locations (Fig. 97). If marks do not line up, repeat procedure.
  7. Install timing belt covers and crankshaft damper.
  8. Install accessory drive belts and cooling fan module.
  9. Install upper radiator crossmember.
  10. Connect negative cable to remote jumper terminal.
  11. Start engine and allow to idle for approximately 1 minute. If a noise is present from the timing belt/tensioner, air has possibly entered the tensioner.
    1. To remove air from tensioner; using a DRB III, operate the engine at speed of 1600-2000 RPM for 10 minutes. This will purge air from tensioner.
NOTE: If air is present, the timing belt tensioner will be soft and may generate noise. This noise should disappear after no more than 15 minutes of engine running time.

Timing chain is only available in the 3.3L and 3.8L engines.

Yours has a belt. (if you're SURE its a 3.0L)

Here is the info on changing it...

3.0L Engine
The timing belt can be inspected by removing the upper front outer timing belt cover.
Working on any engine (especially overhead camshaft engines) requires much care be given to valve timing. It is good practice to set the engine up at TDC No. 1 cylinder firing position before beginning work. Verify that all timing marks on the crankshaft and camshaft sprockets are properly aligned before removing the timing belt and starting camshaft service. This serves as a point of reference for all work that follows. Valve timing is very important and engine damage will result if the work is incorrect.
  1. Disconnect the negative battery cable.
  2. Remove the accessory drive belts. Remove the engine mount insulator from the engine support bracket.
  3. Remove the engine support bracket. Remove the crankshaft pulleys and torsional damper. Remove the timing belt covers.
  4. Rotate the crankshaft until the sprocket timing marks are aligned. The crankshaft sprocket timing mark should align with the oil pump timing mark. The rear camshaft sprocket timing mark should align with the generator bracket timing mark and the front camshaft sprocket timing mark should align with the inner timing belt cover timing mark.
  5. If the belt is to be reused, mark the direction of rotation on the belt for installation reference.
  6. Loosen the timing belt tensioner bolt and remove the timing belt.
  7. If necessary, remove the timing belt tensioner.
  8. Remove the crankshaft sprocket flange shield and crankshaft sprocket.
  9. Hold the camshaft sprocket using spanner tool MB990775, or equivalent, and remove the camshaft sprocket bolt and washer. Remove the camshaft sprocket.
  10. To install:
  11. Install the camshaft sprocket on the camshaft with the retaining bolt and washer. Hold the camshaft sprocket using spanner tool MB990775, or equivalent, and tighten the bolt to 70 ft. lbs. (95 Nm).
  12. Install the crankshaft sprocket.
  13. If removed, install the timing belt tensioner and tensioner spring. Hook the spring upper end to the water pump pin and the lower end to the tensioner bracket with the hook out.
  14. Turn the timing belt tensioner counterclockwise full travel in the adjustment slot and tighten the bolt to temporarily hold it in this position.
  15. Rotate the crankshaft sprocket until its timing mark is aligned with the oil pump timing mark.
  16. Rotate the rear camshaft sprocket until its timing mark is aligned with the timing mark on the generator bracket.
  17. Rotate the front (radiator side) camshaft sprocket until its mark is aligned with the timing mark on the inner timing belt cover.
  18. Install the timing belt on the crankshaft sprocket while keeping the belt tight on the tension side.
  19. Position the timing belt over the front camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the rear camshaft sprocket and finally over the tensioner.
  20. Apply rotating force in the opposite direction to the front camshaft sprocket (radiator side) to create tension on the timing belt tension side. Check that all timing marks are aligned.
  21. Install the crankshaft sprocket flange.
  22. Loosen the tensioner bolt and allow the tensioner spring to tension the belt.
  23. Rotate the crankshaft 2 full turns in a clockwise direction. Turn the crankshaft smoothly and in a clockwise direction only.
  24. Align the timing marks. If all marks are aligned, tighten the tensioner bolt to 250 inch lbs. (28 Nm). Otherwise repeat the installation procedure.
  25. Install the timing belt covers. Install the engine support bracket. Tighten the support bracket mounting bolts to 35 ft. lbs. (47 Nm).
  26. Install the engine mount insulator, torsional damper and crankshaft pulleys. Tighten the crankshaft pulley bolt to 112 ft. lbs. (151 Nm).
  27. Install the accessory drive belts and adjust them to the proper tension.
  28. Reconnect the negative battery cable.
  29. Run the engine and check for proper operation. Road test the vehicle.

You must find the cam lock bar and crank lock pin to do this job properly, otherwise you can bend some valves and that becomes expensive..the front crank damper has a mark to line up with a mark on the timing cover for #1 TDC, but the cam lock bar is what aligns the cams into position. The crank lock pin is helpful but not 100% necessary...

Timing belt alignment


A factory service manual would help, but I'm assuming that if you had one, you probably wouldn't be on this site.

To set the timing, you need to first perform the obvious: remove the accessory drive belts, cam pulley covers, and engine fan and hub. Next you'll need to rotate the engine by hand until the timing marks on the camshaft sprockets and crankshaft are aligned with their corresponding stationary marks. The 0 degree mark on the lower timing belt cover is the timing mark for the crankshaft pulley. There is a mark (small, vertical formed indentation) for the left camshaft pulley on the backing plate behind the pulley near the 1 o` clock position. The same mark exists for the right camshaft pulley only it is on the backing plate near the 8 o`clock position (making it difficult to see). With the crankshaft placed at the zero mark, you can observed where the timing discrepancy exists.

(TIP: Once the right camshaft timing is properly lined up, etch an additional mark on the pulley's face and the backing plate at the 12 o`clock position. This will make it easier to align the pulley for furture adjustments and repairs)

To set the timing correctly, move the crankshaft pulley to 12 deg. BTDC. Being careful to not disturb the position of the crankshaft once it has been moved to that position, remove the crankshaft pulley, lower timing belt cover, timing belt tensioner, and timing belt. Compress the timing belt tensioner and if the original ring pin isn't available to retain the tensioner a small allen wrench can be used to achieve the same results. Line up both camshaft marks and reinstall the timing belt and timing belt tensioner (do not remove the timing belt tensioner tool used to maintain the tensioner piston in a compressed position). When installing the timing belt, be sure to allow the least amount of slack to exisit between the left camshaft pulley and the crankshaft sprocket, but without moving the pulleys.

Next, remove the timing belt tensioner piston retention tool and mount the lower timing belt cover and crankshaft pulley (without fully installing them). Rotate the crankshaft pulley to the 0 deg. mark. If done correctly, moving the crankshaft pulley from 12 deg. BTDC to 0 deg. will remove all remaining slack from the timing belt assembly and the camshaft pulleys and crankshaft pulleys will be lined up with their corresponding marks. Once proper timing has been achieved, install all removed parts.

(Another TIP: I hope it's not necessary, but in case it is, I'll remind you that proper torque of all bolts are necessary as this is an all aluminum engine. Stripping out bolts holes due to over-tightening bolts occurs very easily and become very annoying to deal with [e.g. alternator belts not being able to be tightened completely and constantly squealing every few days, etc.])

Where to put the timing marks on a 96' nissan 2.4 liter


the timing chain tensioner is hydraulic and either out of adjustment or defective.  You need to remove the timing chain cover and reset the mechanical correlation between the crankshaft and the camshafts.  also the other ignition time marks are on the crankshaft harmonic balancer and the cam cover.  Do not crank the engine with the timing out of sequence or you'll destroy the engine.
