yet again
no car body stated, an ISUZU WHAT?> is this too much to ask?
no country,
no year stated,
and the poster dont know all books are indexed by...
drum roll, country model, then year., (all 3 missing, is this fun?)
and this engine, is twin cam.. the correct name is
6ve1 99 to 2004? is 3.5L
the early 2 cam is called 6VD1W (w= 4 cams total)
1998 to 2002 on usa spec troopers (guess #2)
the 2 cams in one head are gear driving side by side,
we have posted this answer on this forum over 5 times
search much>?

did i guess right? so now ill post again this data. using online official sources, not rag books.
photos posted yet again, here we go, the hard way, guessing the freakn car,.. wow.
called the VIN V engine. here.USA>







and the words

1. Verify that the sprocket timing marks are still aligned and that the groove and the keyway on the crankshaft timing sprocket align with the mark on the oil pump. The white pointers on the camshaft timing sprockets should align with the dots on the front plate.
2. Install the timing belt. Use clips to secure the belt onto each sprocket until the installation is complete. Align the dotted marks on the timing belt with the timing mark opposite the groove on the crankshaft sprocket. NOTE The arrows on the timing belt must follow the belt's direction of rotation. The manufacturer's trademark on the belt's spine should be readable left-to-right when the belt is installed.
3. Align the white line on the timing belt with the alignment mark on the right bank camshaft timing pulley. Secure the belt with a clip. WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.
4. Rotate the crankshaft counterclockwise to remove the slack between the crankshaft sprocket and the right camshaft timing belt sprocket.
5. Install the belt around the water pump pulley.
6. Install the belt on the idler pulley.
7. Align the white alignment mark on the timing belt with the alignment mark on the left bank camshaft timing belt sprocket.
8. Install the crankshaft pulley and tighten the center bolt by hand. Rotate the crankshaft pulley clockwise to give slack between the crankshaft timing belt pulley and the right bank camshaft timing belt pulley.
9. Insert a 1.4mm piece of wire through the hole in the pusher to hold the rod in. Install the pusher assembly while pushing the tension pulley toward the belt.
10. Pull the pin out from the pusher to release the rod.
11. Remove the clamps from the sprockets. Rotate the crankshaft pulley clockwise 2 turns. Measure the rod protrusion to ensure it is between 0.16-0.24 in. (4-6mm).
12. If the tensioner pulley bracket pivot bolt was removed, tighten it to 31 ft. lbs. (42 Nm).
13. Tighten the pusher bolts to 14 ft. lbs. (19 Nm).
14. Remove the crankshaft pulley. Install the lower and upper timing belt covers and tighten their bolts to 12 ft. lbs. (17 Nm).
15. Fit the oil cooler hose onto the timing cover and tighten its mounting bracket bolts to 16 ft. lbs. (22 Nm).
16. Install the crankshaft pulley and tighten the pulley bolt to 123 ft. lbs. (167 Nm).
17. Install fan pulley assembly and tighten the bolts to 16 ft. lbs. (22 Nm).
18. Install and adjust the accessory drive belts.
19. Install the cooling fan assembly and tighten the bolts to 72 inch lbs. (8 Nm).
20. Install the upper fan shroud.
21. Install the air cleaner assembly and intake air duct.
22. Connect the negative battery cable

and wants head torque too, need egg in your beer?

1.6 engine, timing belt. 4A not 4AF. F = twin cam.
V.I.N. code 6 not 5, the 5is twin cam 4AFE twin.
the car is a Corolla, and as such info is easy to find on toys,
so that the engine real name is.
http://en.wikipedia.org/wiki/Toyota_A_engine#4A

so you dont want all the facts? marks and how to set tension correctly? really? at #12 and 18?
getting all this right, makes it GO 60k more miles, (a fact)

the words.

1. Remove the timing belt covers using procedures described earlier in this section.
2. If not done as part of the cover removal, rotate the crankshaft clockwise to the TDC/compression position for No. 1 cylinder.
3. Loosen the timing belt idler pulley to relieve the tension on the belt, move the pulley away from the belt and temporarily tighten the bolt to hold it in the loose position.
4. Make matchmarks on the belt and both pulleys showing the exact placement of the belt. Mark an arrow on the belt showing its direction of rotation.
5. Carefully slip the timing belt off the pulleys.
6. dont move cam, with belt off it warns.
7. Remove the idler pulley bolt, pulley and return spring.
8. Use an adjustable wrench mounted on the flats of the camshaft to hold the cam from moving. Loosen the center bolt in the camshaft timing pulley and remove the pulley.
9. Check the timing belt carefully for any signs of cracking or deterioration. Pay particular attention to the area where each tooth or cog attaches to the backing of the belt. If the belt shows signs of damage, check the contact faces of the pulleys for possible burrs or scratches.
10. Check the idler pulley by holding it in your hand and spinning it. It should rotate freely and quietly. Any sign of grinding or abnormal noise indicates replacement of the pulley.
11. Check the free length of the tension spring. Correct length is 38.5mm measured at the inside faces of the hooks. A spring which has stretched during use will not apply the correct tension to the pulley; replace the spring.
12. If you can test the tension of the spring, look for 8.4 lbs. of tension at 50mm of length. If in doubt, replace the spring.
13. Reinstall the camshaft timing belt pulley, making sure the pulley fits properly on the shaft and that the timing marks align correctly. Tighten the center bolt to 43 ft. lbs.
14. Before reinstalling the belt, double check that the crank and camshafts are exactly in their correct positions. The alignment mark on the end of the camshaft bearing cap should show through the small hole in the camshaft pulley and the small mark on the crankshaft timing belt pulley should align with the mark on the oil pump.
15. Reinstall the timing belt idler pulley and the tension spring. Pry the pulley to the left as far as it will go and temporarily tighten the retaining bolt. This will hold the pulley in its loosest position.
16. Install the timing belt, observing the matchmarks made earlier. Make sure the belt is fully and squarely seated on the upper and lower pulleys.
17. Loosen the retaining bolt for the timing belt idler pulley and allow it to tension the belt.
18. Temporarily install the crankshaft pulley bolt and turn the crank clockwise 2 full revolutions from TDC to TDC. Insure that each timing mark realigns exactly.
19. Tighten the timing belt idler pulley retaining bolt to 27 ft. lbs.
20. Measure the timing belt deflection (Tool 23600 B or similar), looking for 5-6mm of deflection at 4.4 pounds of pressure. If the deflection is not correct, readjust the idler pulley by repeating steps 15 through 18.
21. Remove the bolt from the end of the crankshaft.
22. Install the timing belt guide onto the crankshaft and install the lower timing belt cover.
23. Continue reassembly of the timing belt covers as outlined previously in this section.

INSTALLATION
Install the idler pulley to water pump boss.
NOTE
Insert and install the idler pulley to the roll pin that is pressed in the water pump boss.


Install the tensioner arm and plain washer to the cylinder block.
Install the tensioner pulley to the tensioner arm.
Install the camshaft sprockets and align the timing marks.

NOTE
When installing the camshaft sprockets, fasten them tightly while holding the hexagonal part of the camshaft.
Before installing the timing belt, if the timing marks of the cam sprocket and the cylinder head cover do not coincide, do not rotate the cam sprocket more than 3 teeth in either direction.
Rotating the sprocket more than 3 teeth may allow the valve and piston to touch each other.
If the cam sprocket is rotated more than 3 teeth unavoidably, rotate the crankshaft counter - clock wise a bit before rotating the cam sprocket.
Install the auto tensioner to the front case.
NOTE
At this time auto tensioner's set pin should be compressed and secured with set pin.




Align the timing marks of each sprocket and install the timing belt in the following order. Crankshaft sprocket--> Idler pulley--> camshaft sprocket (LH side)--> Water pump pulley--> camshaft sprocket (RH side)--> Tensioner pulley.
NOTE
In this step, No. 1 cylinder is in the TDC (Compression stroke).
Be very careful if you use your fingers.



Pull out the set pin of the auto tensioner.



Install the upper and lower timing belt covers.
Install the power steering pump pulley, idler pulley, tensioner pulley and crankshaft pulley.
Using the wrench [16mm], rotate the tensioner arm clockwise (about 14°) and install the belt to the pulley.
Install the engine cover.
How to adjust the tension of the timing belt
Rotate the crankshaft 2 turns clockwise and measure the projected length of the auto tensioner at TDC (# 1 Compression stroke) after 5 minutes.
The projected length should be 6-8 mm.
Verify that the timing marks of each sprocket are in their specified position.
NOTE
If the timing marks are not in their specified position, repeat from 6 above.

TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o'clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.

The IGNITION timing on your Ranger is computer-controlled and is not adjustable.


Should the camshaft drive belt/timing belt jump timing by a tooth or two, the engine could still run; but very poorly. To visually check for correct timing of the crankshaft, auxiliary shaft, and the camshaft follow this procedure:
There is an access plug provided in the cam drive belt cover so that the camshaft timing cam be checked without moving the drive belt cover.

1. Remove the access plug.
2. Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
3. Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.

Never turn the crankshaft of any of the overhead cam engines in the opposite direction of normal rotation. Backward rotation of the crankshaft may cause the timing belt to slip and alter the timing.
REMOVAL & INSTALLATION

See Figures 1, 2 and 3

Fig. Fig. 1: Timing belt cover on the 2.3L and 2.5L engine

Fig. Fig. 2: Timing belt assembly on the 2.3L and 2.5L engine

Fig. Fig. 3: Releasing the timing belt tensioner using a special tool

1. Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.

1. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.

Here is the trick. Align marks. Put the timing belt on the crank shaft pulley first, and after on the overhead cam pulley. Release tensioner and rotate the crank shaft till the timing belt makes two full circles. Try to align marks, you will be at least one tooth off. Align the crank shaft on the mark, and find out how many teeth you are off at the cam shaft pulley. Count the teeth. Remove the timing belt from cam shaft pulley only. Move cam shaft pulley in reverse according to the number of teeth you counted. Make sure the crank shaft pulley is on the mark. Mount the belt at cam shaft pulley.Rotate the belt two circles and check the marks. Repeate this procedure til after releasing the tensioner, and rotating the timing belt two full circles, the mars will be align.

Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
2. Loosen and position the power steering pump mounting bracket and position it aside.
3. Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
4. Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
5. Remove the timing belt.

To install:

1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.

The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.

1. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
2. Install the crankshaft pulley and belt guide.
3. Install the timing belt cover.
4. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
5. Position the alternator and drive belts, then adjust and tighten it to specifications.
6. Start the engine and check the ignition timing. Adjust the timing, if necessary.

The Isuzu is a strange animal-when you do the timing belt you set it with #1 TDC "BUT" the distributor is timed with TDC #4 I found this the hard way and finally had to buy a cd with the procedures on it. Send me an e-mail address and I will forward the associated pictures &
info to you.
