SOURCE: timing chain mark diagram for a 94 grand am????

Haynes lists the entire procedure for setting the position of the cams etc. Positioning of these is critical...If off by even a slight amount the valves WILL strike the pistons and destroy the engine. DO NOT use any parts made by SA Gear...They have no quality control and will deny any claim made against them. Make sure that the chain guides are in good condition and that the chain tensioner is operating properly.

Need the timing marks for a 2000 alero


please let me know if you have questions.
2.4L Engine
NOTE It is recommended that the entire procedure be reviewed before attempting to service the timing chain.
  1. Before servicing the vehicle, refer to the precautions section.
  2. Drain the cooling system.
  3. Remove or disconnect the following: Negative battery cable, Coolant surge tank, Accessory drive belt, Alternator
  4. Install an engine support.
  5. Remove or disconnect the following: Upper cover fasteners, Front cover vent hose, Right engine mount and bracket, Right front wheel, Right lower splash shield, Crankshaft balancer, Lower cover fasteners, Front cover
  6. Rotate the crankshaft clockwise, as viewed from front of engine (normal rotation) until the camshaft sprocket's timing dowel pin holes align with the timing chain housing holes. The crankshaft sprocket mark should align with the engine mark. The crankshaft sprocket keyway should point upward and align with the cylinder bores centerline. This is the normal timed position.
  7. Remove the timing chain guides.
  8. Remove the timing chain tensioner.
    NOTE Be sure all the slack in the timing chain is above the tensioner assembly when removing it. CAUTION The tensioner plunger is spring loaded and could fly out causing personal injury.
  9. Remove or disconnect the following: Timing chain, Camshaft sprockets

To install:
  1. Install or connect the following: Camshaft sprockets. Torque the bolts to 52 ft. lbs. (70 Nm),
    Camshaft sprocket alignment pin through the camshaft sprockets holes into the timing chain housing holes to position the camshafts for timing.
  2. If the camshafts are out of position and must be rotated more than 1 / 8 turn in order to install the alignment dowel pins, perform the following:
    1. Rotated the crankshaft 90 degrees clockwise off Top Dead Center (TDC) in order to give the valves adequate clearance to open.
    2. Once the camshafts are positioned and the dowels installed, rotate the crankshaft counterclockwise back to TDC.
      WARNING Do not rotate the crankshaft clockwise to TDC or valve and piston damage may occur.
  3. Install the timing chain over the exhaust camshaft sprocket, around the idler sprocket and around the crankshaft sprocket.
    jturcotte_2361.gifjturcotte_2362.gif

    Fig. Timing chain and sprocket alignment positions-2.4L DOHC engine

  4. Remove the alignment dowel pin from the intake camshaft. Using a dowel pin remover tool, rotate the intake camshaft sprocket counterclockwise enough to slide the timing chain over the intake camshaft sprocket. Release the camshaft sprocket wrench. The length of chain between the 2 camshaft sprockets will tighten.
    NOTE If properly timed, the intake camshaft alignment dowel pin should slide in easily. If the dowel pin does not fully index, the camshafts are not timed correctly and the procedure must be repeated.
  5. Leave the alignment dowel pins installed.
  6. With slack removed from chain between intake camshaft sprocket and crankshaft sprocket, the timing marks on the crankshaft and the cylinder block should be aligned. If marks are not aligned, move the chain 1 tooth forward or rearward, remove slack and recheck the marks.
  7. Tighten the chain housing to engine stud. The stud is installed under the timing chain. Torque it to 19 ft. lbs. (26 Nm).
  8. Reload the timing chain tensioner as follows:
    1. Form a keeper from heavy gauge wire.
    2. Slightly, compress the shoe plunger and insert a small screwdriver into the access hole.
    3. Release the ratchet pawl and compress the plunger completely into the hole.
    4. Insert the keeper between the access hole and the blade.
  9. Install or connect the following:
    Tensioner assembly to the chain housing. Torque the bolts to 89 inch lbs. (10 Nm). Tensioner shoe and retainer. Torque the bolts to 89 inch lbs. (10 Nm). NOTE Recheck plunger assembly installation. It is correctly installed when the long end is toward the crankshaft.
  10. Remove the alignment dowel pins. Rotate crankshaft clockwise 2 full rotations. Align the crankshaft timing mark with mark on cylinder block and reinstall alignment dowel pins. Alignment dowel pins will slide in easily if engine is timed correctly.
    WARNING If the engine is not correctly timed, severe engine damage could occur.
  11. Install or connect the following: Timing chain guides, New seal into the front cover by lubricating the seal lip and tapping it into place, Front cover and gaskets. Torque the nuts and bolts to 106 inch lbs. (12 Nm), Crankshaft balancer. Torque the bolt to 129 ft. lbs. (175 Nm), Right front lower splash shield, Front wheel. Torque the nuts to 100 ft. lbs. (140 Nm), Right engine mount bracket. Torque the bolts to 81 ft. lbs. (110 Nm) plus an additional 90 degree turn, Right engine mount. Torque the bolt to 49 ft. lbs. (60 Nm), Upper cover vent hose
  12. Remove the engine support.
  13. Install or connect the following: Alternator. Torque the bolts to 37 ft. lbs. (50 Nm), Accessory drive belt, Coolant surge tank, Negative battery cable.

    Fig. 4: When the camshaft is at TDC, rotate the crankshaft
    counterclockwise 90 degrees to achieve TDC
    84193103.gif


DOHC Engine

  1. Disconnect the negative battery cable.
  2. Remove the timing chain front cover.
    NOTE: During timing chain and sprocket removal, position the
    crankshaft 90 degrees past Top Dead Center (TDC) to make sure the pistons will
    not contact the valves upon assembly.



  3. Carefully rotate the crankshaft clockwise so the timing mark on the
    crankshaft sprocket and keyway align with the main bearing cap split line.
  4. Remove the bolts, then remove the timing guides and tensioner.
  5. Remove the camshaft sprocket bolts, using a 7?8 in. (21mm) wrench
    to hold the camshaft. Then remove the timing chain and camshaft sprocket. Remove
    the crankshaft sprocket, if necessary.
    To install:

  6. Inspect the chain for wear and damage. Check the inside diameter of the
    chain, it should be no more than 23.15 in. (588mm). Inspect the chain guides for
    wear or cracks and the timing sprockets for teeth or key wear. Replace
    components as necessary.
  7. Verify that the crankshaft is positioned 90 degrees clockwise past TDC. The
    crankshaft keyway should be at 3 o'clock aligned with the main bearing cap split
    line to prevent piston and valve damage.
  8. Install the camshaft sprockets, retaining bolts and washers. Make sure the
    letters FRT on the sprockets face forward, away from the cylinder block. Use the
    wrench flats provided on the camshafts to hold the shaft and tighten the bolts
    to 75 ft. lbs. (102 Nm).
  9. Bring the camshafts up to No. 1 TDC by rotating the camshafts and sprocket
    until the dowel pins are at 12 o'clock. Install a 1?6 in. drill bit
    into the hole in the sprocket about 9 o'clock.
  10. If removed, install the crankshaft sprocket, then rotate the crankshaft
    counterclockwise 90 degree up to No. 1 TDC (keyway and sprocket timing mark at
    12 o'clock, in alignment with the block timing mark).
  11. Position the timing chain under the crankshaft sprocket and over the
    camshaft sprockets so 2 silver link plates align with the reference marks on the
    camshaft sprockets and another 2 plates align with the downward tooth (at 6
    o'clock position) on the crankshaft sprocket. Excess chain slack should be
    located on the tensioner side of the cylinder block.
  12. Verify that the crankshaft reference mark aligns with the cylinder block
    mark at 12 o'clock and that the timing pins are installed in the holes at about
    the 9 o'clock position. Remove the timing pins from the camshaft sprockets.
  13. Install the timing chain fixed guide to the right of the block face toward
    the water pump. Tighten the bolts to 21 ft. lbs. (28 Nm) and verify the chain is
    snug against the guide.
  14. Install the pivoting chain guide and check for clearance between the block
    and head. Tighten the bolt to 19 ft. lbs. (26 Nm) and verify the guide pivots
    freely.
  15. Install the 2 forward camshaft bearing caps and the upper timing chain
    guide, then tighten the retaining bolts to 124 inch lbs. (14 Nm).
  16. Retract the tensioner plunger and pin the ratchet lever using a 1?8 in. (3.18mm) No.
    31 drill bit inserted in the alignment hole at the lower front of the component.
    Install the tensioner and tighten the bolts to 14 ft. lbs. (19 Nm), then remove
    the drill bit.
  17. Make one final check to verify all components are properly timed, then
    remove all timing pins.
  18. Install the timing chain front cover.
  19. Connect the negative battery cable, start the engine and check for leaks.

I have a 99 dodge intrepid that threw a rod and my father-in-law and I have been trying to time the car for a year now. We get number one piston up but the mark on the oil pump doesnt line up with the mark...


I'm not sure what you may be "doing wrong", but here is the manufacturer procedure for aligning the timing marks.
d753c93.gif
98f82f3.gif
^Refer to this diagram during step 12.
046beb2.gif
^Refer to this diagram during step 13.
95add8f.gif
^Refer to this diagram for step 19.

1. Align crankshaft sprocket timing mark to the mark on oil pump housing. NOTE: Lubricate timing chain and guides with engine oil before installation.
2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.
3. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
4. Loosely position left side camshaft sprocket over camshaft hub.
5. Align timing (plated) link to the crankshaft sprocket timing mark.
6. Position primary chain onto water pump drive sprocket.
7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.
8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
9. Install left side lower chain guide and tensioner arm. Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary.
10. Install chain guide access plug to left side cylinder head. Tighten plug to 20 Nm (15 ft. lbs.)
11. NOTE:
To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.
12. Purge oil from timing chain tensioner using the following procedure:
a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
13. Reset timing chain tensioner using the following procedure:
a) Position cylinder plunger into the deeper end of Special Tool 8186.
b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
14. Install the reset chain tensioner into the right cylinder head.
15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
21. Install camshaft position sensor and connect electrical connector.

Hope this helps!

If the timing chain/belt is to be reused, mark the direction of rotation on the timing chain/belt.

19. Loosen the timing chain/belt tensioner nut.

  1. Remove the timing chain/belt.
Installation
NOTE: Ensure that the timing marks on the camshaft sprockets (6256) and the seal plate are properly aligned. Ensure that the timing marks on the crankshaft sprocket and the oil pump housing are still aligned.



stv~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Pay special attention to the tooth shape of the timing belt. The current timing belts are not interchangeable with the timing belts from the 1993 model year. The 1993 model year uses a square or trapezoidal tooth timing belt while the current model year uses a rounded tooth design. The design change was made to extend the service life of the timing belt from 60,000 miles for the square or trapezoidal toothed belt to 105,000 miles for the rounded tooth belt. If the proper timing belt is not used, the customer may complain of a "whining" noise coming from the engine compartment. If the camshaft sprocket has a square cut in the valley of the gear tooth, it will require a square or trapezoidal tooth timing belt. If the camshaft sprocket has a rounded cut in the valley of the gear tooth, it will require a rounded tooth timing belt.
NOTE: If a new timing chain/belt is to be installed, make sure that the arrow is pointing away from the engine. If a timing chain/belt is to be reused, make sure that the directional arrow that was marked during disassembly is facing the correct direction.

NOTE: A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts and the crankshaft. These marks will help ensure that the engine (6007) is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the sprocket. Because the white timing marks are not evenly spaced you will need to refer to the following illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket.

NOTE: Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump (6600).

Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprockets following a counterclockwise path. Do not allow any slack in the timing chain/belt between the timing sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner.

  1. While holding the timing chain/belt tensioner with an Allen wrench, loosen the timing chain/belt tensioner nut.
  1. Allow the timing chain/belt tensioner to put pressure on the timing chain/belt.
  1. Use an Allen wrench to turn the timing chain/belt tensioner 70-80 degrees clockwise and tighten the timing chain/belt tensioner nut to 43-58 Nm (32-43 lb-ft).

    1. Rotate the crankshaft (6303) clockwise twice and align the No. 1 piston to Top Dead Center (TDC) on its compression stroke.
    1. Apply 98N (22 lbs) of force on the timing chain/belt between the rear camshaft sprocket and the timing chain/belt tensioner.
    2. NOTE: An assistant may be needed to adjust the timing chain/belt.

      While holding the timing chain/belt tensioner steady with an Allen wrench, loosen the timing chain/belt tensioner nut. Remove the Allen wrench and adjust the timing chain/belt tensioner as follows:
      1. Install a 0.35mm (0.0138 inch) thick and 12.7mm (0.500 inch) wide feeler gauge as shown.

  1. Turn the crankshaft clockwise to position the feeler gauge between the timing chain/belt tensioner and the timing chain/belt

  1. Tighten the timing chain/belt tensioner nut to 43-58 Nm (32-43 lb-ft).
  1. Turn the crankshaft clockwise to remove the feeler gauge from between the timing chain/belt tensioner and the timing chain/belt.
  1. Rotate the crankshaft clockwise twice and align the No. 1 piston to TDC on its compression stroke.
  1. Apply 98N (22 lbs) of force on the timing chain/belt between the rear and front camshaft sprocket.
    1. Measure the timing chain/belt deflection. Timing chain/belt deflection should be between 13-15mm (0.51-0.59 inch). If timing chain/belt deflection is not within specification, repeat steps 3-11. If the timing chain/belt cannot be adjusted to within specification, the timing chain/belt will have to be replaced.
    1. Position the lower engine front cover and install the five lower engine front cover bolts. Tighten the five lower engine front cover bolts to 3-5 Nm (27-44 lb-in).
    1. Install the outer timing chain/belt guide and the crankshaft pulley. Refer to the procedure in this section.
    1. Position the water pump pulley on the water pump and install the four water pump pulley bolts
    1. Use Strap Wrench D85L-6000-A or equivalent to hold the water pump pulley, and tighten the four water pump pulley bolts to 16-21 Nm (12-15 lb-ft).
    1. Position the RH outer engine and transmission splash shield and install the four RH outer engine and transmission splash shield bolts and two screws.
    1. Install the RH front wheel and tire assembly. Tighten the lug nuts (1012) to 98-118 Nm (72-87 lb-ft).

Here is All Lititure But Pictures Wont show up on FixYa for some reason, I can Email it ALL to you Just Send Me A Request to my Nickname here @aol.com


SPECIAL TOOLS REQUIRED (or equivalents)
  • J-36008, Camshaft sprocket timing alignment pins.
  • J-39579, Camshaft sprocket wrench.
CAUTIONS:
  • The timing chain on the 1996 LD9 (VIN T) Twin Cam Engine is not to be replaced with the timing chain from any other model year. The timing sprockets are different on the Twin Cam Engine and the shape of the links matches the sprockets. Engine damage may result if the wrong timing chain is used.
  • The timing chain and crankshaft sprocket MUST be marked so that they are reinstalled with the same side facing out at the time of reassembly.
  • Failure to follow the removal and installation procedures could result in severe engine damage.
REMOVE OR DISCONNECT
  1. Negative battery cable.
  2. Front cover, refer to Timing Cover / Service and Repair .
  3. Rotate crankshaft in clockwise direction until camshaft and crankshaft timing marks are aligned.
  4. Timing chain guides.
  5. Raise and support vehicle.
  6. Ensure slack in timing chain is above tensioner assembly, then remove chain tensioner. The timing chain must be disengaged from grooves in tensioner shoe to permit removal of shoe. Position a suitable screwdriver under timing chain while pulling shoe outward. If difficulty is encountered in removing tensioner shoe, proceed as follows:
    1. Lower vehicle, then while holding the intake camshaft sprocket with J-39579, remove sprocket bolt and washer.
    2. Remove washer, then install bolt into camshaft by hand.
    3. Position a suitable three jaw puller into intake camshaft sprocket relief holes and remove sprocket. CAUTION: Do NOT pry on camshaft sprocket as damage to sprocket or timing chain housing may result.
  1. Tensioner assembly attaching bolts and tensioner assembly.
  2. MARK CRANKSHAFT SPROCKET AND TIMING CHAIN outer surface for reassembly.
  3. Timing chain.
INSTALL OR CONNECT
  1. Intake camshaft sprocket onto camshaft with surface marked during removal showing.
  2. Intake camshaft sprocket retaining bolt and washer, torque to 70 Nm (52 ft lbs) while holding the sprocket with J-39579 (if removed).
  3. Timing pins, J-36008, through holes in camshaft sprockets into holes in timing chain housing to position camshafts for proper timing. If camshafts are out of position and must be rotated more that 1/8 turn to insert timing pins:
    1. Crankshaft MUST be rotated 90°clockwise off of TDC in order to give the valves adequate clearance to open.
    2. Once the camshafts are in position and the timing pins have been installed rotate crankshaft COUNTERCLOCKWISE to TDC. CAUTION: Do NOT rotate the crankshaft clockwise to TDC, valve or piston damage could occur.
  1. Timing chain over exhaust camshaft sprocket, around idler sprocket and around crankshaft sprocket.
  2. Set camshaft sprockets at timed position and install timing chain. Remove timing pin from intake camshaft. Using J-39579, rotate the intake camshaft sprocket counterclockwise until timing chain can be installed over sprocket. Release J-39579 after timing chain has been installed over sprocket. The length of chain between intake and exhaust camshaft sprockets should tighten. The timing pin should easily fit through intake camshaft sprocket timing hole into timing chain housing timing hole. If timing pin does not fully index, the camshafts are NOT timed correctly and the procedure MUST be repeated.
  3. With timing pins installed, raise and support vehicle.
  4. With slack removed from timing chain between intake camshaft sprocket and crankshaft sprocket, timing marks on crankshaft and engine block should be aligned. If the marks are not aligned, move timing chain one tooth forward or rearward to align marks. Remove slack and recheck marks.
  5. Reload tensioner assembly to zero position as follows:
    1. Form a keeper out of heavy gauge wire into a U-shaped piece with a half inch opening.
    2. Apply slight force on tensioner blade to compress plunger.
    3. Insert small screwdriver into reset access hole and pry rachet pawl away from ratchet teeth while forcing the plunger completely in the hole.
    4. Install keeper between access hole and blade.
  1. Tensioner assembly to chain housing and recheck plunger assembly installation, noting long end is toward crankshaft.
  2. Tighten timing chain tensioner bolts to 10 Nm (89 in lbs) .
  3. Lower vehicle to point where timing pins can be removed from camshaft sprockets.
  4. Rotate crankshaft two revolutions in the clockwise direction. Align crankshaft keyway with the mark on cylinder block and reinstall timing pins through camshaft sprockets into housing timing holes. Timing pins should slide easily through timing holes. If timing pins cannot be inserted easily, repeat procedure to properly time engine. CAUTION: If the engine is not correctly timed, severe engine damage could occur.
  5. Timing chain guides.
  6. Engine front cover.
  7. Negative battery cable.
