On the 1.6 DOHC also I have found that the small holes next to the cam timing mark you can put a drill bit or bolt in there's a hole in the back on the head they will fit in jit will aline them prefect plus hold them in place don't forget to remove them prior to turning the motor over makes a hell of a noise trust me on that one ??

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.

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.

SOURCE: 91 geo storm overheats

Leaks water under the dash or antifreeze. Sounds like it needs a heater core. If you replaced the thermostat it might still have air trapped in it.

Install serpentine belt on 91 geo storm

I believe this is for 1.8L engine, serpentine belt. If you have a different belt for each component, that is a different issue? With multiple belts, the component usually has a pivot bolt, you loosen the bolt, then move the component to release or increase tension on the belt, then tighten the bolt.
With a serpentine belt, the tensioner does that for you.

Timing marks on 1.6 dual over head cam

the geo storm, 1.6 DOHC
the FSM cover it, so does alldata.com
hint 2, its an Isuzu engine.
its really (makes information easier to find )
Isuzu:
4XE1-UW a DOHC 16-valve engine with 130 hp (97 kW)
he DOHC engine was used in the 1990-1991 Isuzu Impulse XS, in the 1990-1991 Isuzu Stylus XS, in the 1990-1991 Geo Storm GSi, and the M100 Lotus Elan.
all that off the wiki,,
all cars rare here.....

1st google hit
http://www.robietherobot.com/storm/torquespecs.htm

This engine is interference type
so when timed, with a new belt
roll engine by hand, with spark plugs out.? do pistons hit valves.
yes, stop, the cam is timed wrong.
no, do a compression test on #1, if pass, do all 4. 150psi min.w.o.t.
wide open throttle
a better test, is a leak down test. x4. by hand.
these acts of kindness to the engine, saves most engines.

if the leak down fails, the timing is wrong, or the valves are already
bent..
dont use a fleabay china belt, bet a GATES belt. (they last)
setting the tension is very important to a full life .

91 Geo Storm Gsi running just fine, one day I lost power driving 65, check engine light came on and was flickering, mph arm going up and down but didn't die then. Then it was ok.That happened 2 times...

Most engines don't fair well under extreme heat. It's apparent you might have some electrical issue's. Your rpm's or mph arm going up and down could be faulty speed sensor would cause arm problem. I think you may have more than one problem, the car shutting off is due to engine over-heating. Check cooling system-thermostat, water pump, radiator, engine fans and coolant temp sensor and fan relay's. It could be as simple as blown radiator hose.
