Diagram timing of v6 engine of liberty 2001 model


2001 , no such ani-mule !
"Introduced for the 2002 model year as a replacement for the Cherokee (XJ),"
you meant manufactures date not model and reg. date. sure.
2002 !
3.7L V6 (cop spark ) chain drive cams....
timing ( cam or spark?)
"Ignition timing is controlled by the Powertrain Control Module (PCM). No adjustment is possible"
so Cam timing (alldata.com covers this in detail)
why not post the context, Im doing what.?
im doing a 60k belt swap
or it slipped. or think id did.
or just put in a new head or cam? see , context is 100% important.
im here, going to there.....
im on line, and it shows 4 engines, i think that is wrong, but...

you must be asking chain cam sprocket timing.
im at alldata.com (or FSM)
there are 37 install steps, im not sure what step you want me
to pluck out. but here is my guess. step 8 ,9,10
  1. Install both secondary chains onto the idler sprocket. Align two plated links on the secondary chains to be visible through the two lower openings on the idler sprocket (4 o'clock and 8 o'clock). Once the secondary timing chains are installed, position special tool 8429 to hold chains in place for installation.
  2. Align primary chain double plated links with the timing mark at 12 o'clock on the idler sprocket.
  3. Align the primary chain single plated link with the timing mark at 6 o'clock on the crankshaft sprocket.
step 12:
Install all chains, crankshaft sprocket, and idler sprocket as an assembly . After guiding both secondary chains through the block and cylinder head openings, affix chains with a elastic strap or equivalent. This will maintain tension on chains to aid in installation. Align the timing mark on the idler sprocket gear to the timing mark on the counterbalance shaft drive gear, then seat idler sprocket fully . Before installing idler sprocket bolt, lubricate washer with oil, and tighten idler sprocket assembly retaining bolt to 25 ft. lbs. (34 Nm).

step 13:
  1. Align left camshaft sprocket "L" dot to plated link on chain.
  2. Align right camshaft sprocket "R" dot to plated link on chain.

step 15/16
  1. Remove Special Tool 8429, then attach both sprockets to camshafts. Remove excess oil from bolts, then Install sprocket bolts, but do not tighten at this time.
  2. Verify that all plated links are aligned with the marks on all sprockets and the "V6" marks on camshaft sprockets are at the 12 o'clock position.

do ask questions, or login to alldata.com or mitchels
or get a real FSM.
its nothing trivial.

in fact get the book before the job. so are perpared.

Where are the timing marks on a 1994 honda civic 1.5


On the Cam gear are three marks. On the face of the gear it should say "up", then you have three marks one at 3 o'clock one at 7 o'clock one at 9 o'clock. the one at 7 should align up with a mark on the block. Some have a raised semicircle and you line up the 7 o'clock mark on the cam with the far left hand end of that semicircle. Now on the crack end you have a mark at the 2 o'clock position and it lines up with a mark on the block. Do not turn the crank or the cam independent of one another, as the valves can be bent. Remove the spark plugs to ease turning the engine when needed. The engine will turn counterclockwise. Remove all necessary left hand front wheel, inner fender splash guard, covers, top engine mount. turn the engine until number 1 cyl. is at TDC compression stroke, and all timing marks align as noted. Remove the lower crankshaft bolt and pulley, and lower belt cover. Loosen tensioner bolt and push it out of your way and remove the belt. Put on the new timing belt in this order, crank sprocket, cam sprocket, water pump sprocket, tensioner. Belt must be tight on no tensioner side. Push the tensioner against the belt. Turn the engine 4 turns counterclockwise, until the timing marks realign, loosen the tensioner and turn the engine again 3 teeth, torque the tensioner to 30 flbs. reinstall all the mounts and covers. all should be good.

When doin the timing belt on a 94 saab 900 dohc v6 are the timing marks suppose to move after you adjust the tentioners


Sort of. If you have the slack on the wrong side, it is possible for you to end up a tooth off after adding the tension. The only way to be sure is to manually turn the crank 2 turns, and line the marks back up again.
Make sure you only go the right way. You can't back up of you over shoot.
If it is half a tooth off, there is nothing you can do about it. But if you are a whole tooth off, release the tensioner and do it again.
But remember the movement of the crank means only half what the movement of the cam means. So you can have more slop in the crank than the cam.

Not good.....replacing timing belt on saab


I'm certain that the camshaft pullies and probably the head have reference marks that must be aligned. I can't tell you how to set them however and I think you know that guessing could be very expensive.
Check you local library for a Haynes (1st choice) or Chilton service manual or, and I think everyone should own one for their vehicle, buy one. We have three different vehicles and each has its own manual. They are not only valuable for DIY stuff but also for judging the fairness of an estimate on a repair you don't want to do at home. They cost between $20-$30 US and considering what mistakes cost, that's cheap.

1997 nissan pathfinder timing off. I replaced water pump(behind timing belt). Timing "gears" got moved (two top ones). I don't know how to make sure everything is lined back up correctly.Any ideas?


The cam sprockets should have marks on them (dimples) that should align with marks on the rear timing cover. There should also be a similar dimple on the crankshaft timing sprocket. These will align with their respective marks when the engine is at TDC. The alignment marks are in the following locations as you look at the front of the engine: RH cam sprocket at approximately 11:00, LH cam sprocket at approx 1:00, Crankshaft timing sprocket at approx 4:00 or 5:00. IF you can't find the marks on the cover, put the marks on the sprockets in those approximate positions and set the belt by using a belt tooth count between the marks. Cam to cam should be 40 teeth between the cam marks. Between the LH sprocket and the crank mark should be 43 teeth. You can check TDC by removing your number 1 cylinder spark plug and carefully inserting a long screwdriver and watching the rise/fall as you hand crank the crankshaft into position (which is much easier with the plugs out)

Remove the belt from the coolant pump pulley and slowly release the belt tensioner. STEP 3 Remove the belt tensioner and remove the steering pump pulley STEP 4 Remove the water pump pulley use the engine bracket to pry against. STEP 5 Remove the timing cover and Remove the right-hand front wheel and the cover in the wheel housing. STEP 6 Remove the crankshaft pulley (undo the six bolts but do not remove the centre bolt). STEP 7 Place the engine top dead center and Zero the engine. The markings on the camshaft sprockets and timing cover should be in alignment as also should the marking on the crankshaft. Use locking tools 83 95 006 and KM-800-2 for the camshaft sprockets and locking tool KM-800-10 for the crankshaft (These tools can be purchased from Saab (18774177222) or from Baum Tools). STEP 8 Before removing the toothed belt mark its direction of rotation . To facilitate refitting the belt can be marked at both the camshaft marking and the crankshaft marking. STE9cc7b85.jpgP 9
STEP 10 Fit the toothed belt according to the marked direction of rotation. Use setting tool 83 95 006 to keep the belt in place and adjust the tensioning roller loosely by hand to prevent the belt from jumping off. Adjust counterclockwise. Fit a section of the toothed belt and fit tool 83 93 985 to measure the belt tension. Loosely tighten the centre bolts of the adjusting rollers. Adjust the lower adjusting roller counter clockwise to a belt tension of 275-300 Nm. Turning torque 30 lb.ft ft ******The adjustment of the belt tension is for preparation ONLY and must not be used as a check when the belt adjusted for the final time! STEP 11 Turn the engine over two revolutions until just before the zero mark and place the locking tool on the crankshaft. Carefully turn the crankshaft in the direction of engine rotation until the arm rests against the coolant pump's flange and then tighten the arm. Fit setting tool 8395006 and check that the markings on the camshaft sprockets are aligned with the markings in the tool. ********Check that the A marking is approximately 2mm above B marking. If the distance is less readjustment is necessary. STEP 12 Fit the crankshaft pulley and Tighten to a torque of 15 foot lbs. STEP 13 Reinstall the inner wheel cover and front right wheel.
