old post
answer is :
same as Isuzu Impulse
4XE1
my guess would be for 90. the single cam version
the best source of data is alldata.com
or on the storm forums.
some links here.

steps: (quote)
The notch on the crankshaft pulley should align with the 0 degrees mark on the timing gear case. Make sure the rocker arms on the No. 1 cylinder are loose and the rockers on the No. 4 cylinder are tight. If not, turn the crankshaft one complete revolution and align the marks again.

Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 1 cylinder, then the intake valves on the No. 2 cylinder and the exhaust valves on the No. 3 cylinder. Note readings.

Rotate the crankshaft 360 degrees. Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 4 cylinder, then the intake valves on the No. 3 cylinder and the exhaust valves on the No. 2 cylinder. Note readings.

The valve clearance obtained on the exhaust valves should be between 0.008-0.012 in. (0.20-0.30mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 (valve lash spring spacer) between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.

The rear camshaft bearing caps must be removed to remove the selective shim.

The valve clearance obtained on the intake valves should be between 0.004-0.008 in. (0.10-0.20mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.

When the adjustment is completed, install the cylinder head covers and connect the battery negative cable. Start the engine and check for leaks.

the real question is.
where do i get shims from a dead car company if in USA? now that be the big question.

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

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 .

gm /isuzu , frankencar.
no photos posted. so how can we guess?

belt slippping.
bad alt (reg)
battery has issues. even corroded bat lugs.

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.

Make: GEO
Model: STORM
Year: 1990
Engine: L4 - 1.6L - FI - - GAS

Hope helps.

if the fan is not blowing its probably bad connection at the motor remove fan cover check connection. No heat check coolant level.maybe thermostats bad, faulty radiator or water pump

it is on the front of the engine and yeas it has one, it is located under the camshaft drive belt cover and drive by the camshaft belt, both will need to be replaced. see picture below

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.
