SOURCE: how to set the timeing on 91 geo storm

The timing marks are located near the top of the crankshaft pulley on the plastic timing belt cover. There is a notch in the pulley to mark TDC (Top Dead Center)
Align the notch with the 0 mark on the plastic cover to set your base timing.
Ground the proper circuit on the ALDL connecter located under the dashboard somewhere under the steering wheel. Check the manual for the proper circuit to ground.
With the engine warm and the circuit grounded. Set the proper timing. Un-ground the circuit and you are done.

Timing Belt - REMOVAL & INSTALLATION

Although timing belts may last for thousands of miles past the recommended replacement interval, they should be replaced every 60,000 miles to prevent trouble or damage should they snap. Timing belts do not usually give an indication that they are worn or aging without removing the cover(s) and inspecting the belt. A worn or damaged belt could give out at any time. In some cases, should a timing belt snap while the engine is running, damage could be done to the valve trains or pistons requiring a partial or full engine disassembly. Also, should the belt go when the vehicle is far from home, a costly tow or even more costly repair job and considerable inconvenience may be suffered.
Timing belts must always be handled carefully and kept completely free of dirt, grease, fluids and lubricants. This includes any accidental contact from spillage, fingerprints, rags, etc.. These same precautions apply to the pulleys and contact surfaces on which the belt rides.The belt must never be crimped, twisted or bent. Never use tools to pry or wedge the belt into place. Such actions will damage the structure of the belt and possibly cause breakage.


Spectrum
(see Figures 1, 2 and 3)
The engine must be removed from the vehicle for this procedure to be performed.

  1. Remove the engine and mount it to an engine stand.
  2. Remove the accessory drive belts.
  3. Remove the engine mounting bracket from the timing cover.
  4. Rotate the crankshaft until the notch on the crankshaft pulley aligns with the 0 degree mark on the timing cover and the No. 4 cylinder is on TDC of the compression stroke.
  5. Remove the starter and install the flywheel holding tool No. J-35271 or equivalent.
  6. Remove the crankshaft bolt, boss and pulley.
  7. Remove the timing cover bolts and the timing cover.
  8. Loosen the tension pulley bolt.
  9. Insert an Allen wrench into the tension pulley hexagonal hole and loosen the timing belt by turning the tension pulley clockwise.
  10. Remove the timing belt.
  11. Remove the head cover.
Inspect the timing belt for signs of cracking, abnormal wear and hardening. Never expose the belt to oil, sunlight or heat. Avoid excessive bending, twisting or stretching.
To install:
  1. Position the Woodruff key in the crankshaft followed by the crankshaft timing gear. Align the groove on the timing gear with the mark on the oil pump.
  2. Align the camshaft timing gear mark with the upper surface of the cylinder head and the dowel pin in its uppermost position.
  3. Place the timing belt arrow in the direction of the engine rotation and install the timing belt, first to the crankshaft pulley, next to the camshaft pulley, then to the water pump pulley and finally to the tension pulley. Tighten the tension pulley bolt.
Once installed, there must be not slack in the timing belt. The belt teeth must be in perfect alignment with the gears.
  1. Turn the crankshaft 2 complete revolutions and realign the crankshaft timing gear groove with the mark on the oil pump.
  2. Loosen the tension pulley bolt and apply tension to the belt using an Allen wrench in the hexagonal pulley hole. Torque the pulley bolt to 37 ft. lbs. (50 Nm) while holding the pulley stationary.
  3. Check the timing belt tension using a belt tension gauge, it should be 40-48 lbs. (18-22 Kg).
  4. Adjust the valve clearances.
  5. To complete the installation, reverse the removal procedures. Torque the crankshaft pulley-to-crankshaft bolt to 108 ft. lbs. (147 Nm).

I need the timing marks for belt replacement on the 1.6L SOHC 1990 Geo Prizm


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.

Does 1992 geo storm gsi have timing belt or timing chain


great question. but confuses <STORM (an ISUZU) with METRO, Swift.
ill assume the STORM is correct and the 1.8l too.
that engine is a ISUZU Real engine,
and is called the
4XF1 ,see facts below.
now the cam answer.

in the uSA this car is the GSI model with 1.8L
see last link for your answer. below. GM official page.
you can also see your cam in the 2nd link below.
the engine is INTERFERENCE. so if the belt snaps, it bends valves
just like all HONDAs do.\
http://www.agcoauto.com/content/List_Of_Interference_Engines


wiki facts.
The larger 1.8 L 4XF1 DOHC replaced the 4XE1 in North America and produces 140 hp (104 kW) and 125 ft/lb (169 Nm) of torque. This engine was used in the 1992-1993 Geo Storm GSi, in the 1992 Isuzu Stylus RS, and in the Asuna Sunfire. In Japan it was installed in the Isuzu Piazza, where it had 150 PS (110 kW).

Ichanged the head on my 91 geo storm 1.6 dohc and now it won't start


Double check crankshaft timing mark, on your lower timing cover has some timing marks - crankshaft should be on the 0 mark. Camshaft timing marks--intake camshaft mark set at 3 o'clock and exhaust camshaft mark set a 9 o'clock. These timing marks are critical for motor to run and start correctly. These timings marks can move while trying to install the timing belt. After, you confirm or reset timing and belt, you can confirm timing is correct by rotating the crankshaft twice. Your timing marks should be on right on timing marks discussed at the top of the page. If timing marks are off, start over with timing process.

Timing belt replacement. what are the mark settings on the pulleys?


If you dont know the marks on an engine when replacing the timing belt. There are usually marks on the pulleys and housings to line up. Put the engine on top dead centre TDC from the crankshaft marks before looking for the other marks. If you cant find them Use white out to place your own marks on the pulleys and housings before removing the old belt . To be sure nothing gets out of line mark any pulley that has teeth. It can be useful to take a few digital photos . When fitting the new belt make sure your marks line up again.

I need the diagram for a timing belt on a 1992 geo storm


The timing belt will only run between the crank and the cam(s). Usually has a tensioner on one side. You'll need to know where to set the cam(s) and crank to reinstall it.

Or do you mean the accessory belt?

Need to install serpentine belt on 1992 geo storm.Is there a tension pulley and how do you loosen it to get new belt on?


Removal & Installation
  1. Except for the 1.8L engine, loosen the pivot and anchor bolts on 1 of the belt's components, then pivot the component sufficiently to release belt tension and remove belt.
  2. For the 1.8L engine, use a 3/8 in. breaker bar or ratchet to pivot the belt tensioner and release the serpentine drive belt, then remove the belt from the pulleys and the vehicle.
To install:
  1. Position the belt over the pulleys.
  2. For the 1.8L engine, pivot the tensioner and install the serpentine belt. Make sure the belt is properly aligned in all of the pulley grooves, then gently pivot the tensioner into contact with the belt. Do not allow the tensioner to snap into position or damage could occur.
  3. Except for the 1.8L engine, adjust the belt tension and tighten the accessory mounting bolts.

Severe lack of power 1991 Geo Storm,


When you say "fixed", do you mean that you put the new belt on it?
If so, you probably missed a tooth in the belt placement. This usually happens when you wrap the wrong way during the procedure and the marks don't end up lining up.
Also check for other things like pinched wires or something disconnected that didn't get put back in the right spot. (vacuum lines?)

How to set the timeing on 91 geo storm


The timing marks are located near the top of the crankshaft pulley on the plastic timing belt cover. There is a notch in the pulley to mark TDC (Top Dead Center)
Align the notch with the 0 mark on the plastic cover to set your base timing.
Ground the proper circuit on the ALDL connecter located under the dashboard somewhere under the steering wheel. Check the manual for the proper circuit to ground.
With the engine warm and the circuit grounded. Set the proper timing. Un-ground the circuit and you are done.
