Hi. Here are thi information that you need.
I hope this solve your problem,
This figure is for the crankshaft. look the mark at lower of the cover.
OK. this figure is for the camshaft . look the marks at uppur of the back cover and on the sprockets.
OK> If this information is good for you Just RATE it.
Thank you for use fixya.

no timing marks on cover, timing marks are on sprokets they should be lined oposite each other.

Required tools:
13mm open end wrench 10mm shallow and deep socket 8mm socket long flathead screwdriver 17mm deep socket T50 torx socket 1/4", 3/8ths and 1/2" ratchets and extensions E10 inverted torx sockets 6mm Allen wrench 15mm open end wrench 7mm socket 12mm open end wrench 14mm socket 12mm socket 8mm, 9mm and 10mm Allen head sockets 19mm socket pry bar needle nose pliers
If you are doing this because your timing belt broke you will also need to buy a complete cylinder head, head gasket set, and both idler pulleys. ALL DAEWOO MODELS WILL BREAK THE INTAKE AND EXHAUST VALVES WHEN THE TIMING BELT BREAKS.
Start by removing the air cleaner assembly from the throttle body, remove the air filter and housing jack up the vehicle and remove the wheel, remove the plastic shielding in front of the accessory drive belt assembly, remove the accessory drive belt, place a jack with a block of wood on top underneath the engine oil pan remove the front engine mount, remove the crank shaft pulley ( the 4 Allen head bolts only not the 17mm bolt in the center.) remove the metal plate behind the engine mount bracket on the engine, remove the plastic timing belt cover 3 clips on top 2 10mm bolts on bottom. Rotate the engine until the #1 cyl. is at Top Dead Center on the compression stroke or line up the crankshaft timing mark with the mark on the inner timing belt cover ( notch in cover with notch in pulley) on the camshaft pulleys -- ( intake cam line up the line on the pulley with the line on the inner cover)( exhaust cam line up the arrow on the pulley with the arrow on the inner cover) loosen the 13mm bolt in the belt tensioner and using the Allen wrench rotate the tab until there is slack in the belt. Remove the belt. At this time I would recommend you replace the water pump, both plastic idler pulleys as they tend to overheat and lockup, and the belt tensioner. Make sure all your marks are lined up, you may need a helper to hold the Exhaust Cam in place as it tends to move during belt installation. Put the timing belt underneath the crankshaft pulley, install the belt leaving the intake cam for last and NO BELT SLACK on the right side between the crank and the exhaust cam. Once the belt is installed rotate the crankshaft over 2 revolutions and make sure is rotates freely, and your timing marks are aligned perfectly if not the engine will not run properly, tension the belt as needed. Installation is the same as removal.
To clarify, on the DOHC engine, the intake cam gear has a line on it, and the exhaust cam gear has an arrow on it. These should be lined up with the corresponding line and arrow on the VALVE COVER, pointing straight up. I just went through this process over the weekend, and spent quite a bit of time looking for these marking as I had removed the valve cover. Once I found them, it was plain and simple.
In addition, be sure to not over tighten the belt when reinstalling. The tensioner has markings on it for "old" and "new". DO NOT adjust past "new", as the car will sound like a jet engine, and the belt will not last for very long.
One more item that you may as well replace while you are in there is the cam position sensor if you have not already, as there have been issues with them, and the timing housing has to be opened to get to it

Instructions
Difficulty: Moderate
Things You’ll Need:
Step1
Raise and support the vehicle
on jack stands. Remove the intake air temperature wiring, the breather
hose and intake air hose. Take off the air cleaner assembly.
Step2
Remove the right wheel. Remove the accessory belts. Remove the
crankshaft bolt and the crankshaft pulley. Remove the power steering
bolts and the timing belt covers. Temporarily install the crankshaft
bolt and turn the engine clockwise until the mark on the crankshaft
pulley, which is a triangle stamped into the crank sprocket, is aligned
with the corresponding triangular mark on the block.
Step3
Make sure that the timing marks are aligned on the camshaft sprockets.
These are a line on each sprocket that runs through a tooth on each
sprocket. These lines should line up in the middle between each
sprocket and point toward each other. If they do not line up, turn the
crankshaft one more time and they will line up. It takes two turns of
the crank to one complete revolution of the cam.
Step4
Loosen the water pump bolts; using the 3/8-inch ratchet, turn the water
pump clockwise away from the belt and loosely tighten the bolts to keep
it there. Remove the timing belt.
Make sure the timing marks are aligned and install the new belt
starting on the right side from the crank sprocket and working
counterclockwise. Keep all the belt tension on the right side away from
the tensioner.
Step5
Loosen the bolts in the water pump and rotate the water pump
counterclockwise to apply tension to the belt. Watch the tensioner,
which is above the water pump, and apply tension with the water pump
until the pointer on the tensioner lines up with the notch above it.
Lightly tighten the water-pump bolts.
Step6
Turn the engine
two more times and align the timing marks perfectly. Loosen the
water-pump bolts and, using the ratchet, apply tension to the belt
until the tensioner pointers are aligned. Tighten the water-pump bolts.
Step7
Install the timing-belt covers and the bolts in the power-steering pump
and tighten. Remove the crankshaft bolt and install the crank pulley
and the bolt, then torque the crankshaft pulley bolt to 70 foot pounds
of torque. Install all components in reverse order of removal.

here are the timming marks
the other important thing is to
Rotate the automatic tensioner hex–key tab anti-clockwise until the adjust arm pointer of the timing belt automatic tensioner is aligned with the notch in the timing belt automatic tensioner bracket.
then turn engine over 2 turns and recheck marks and tensioner pointer
