SOURCE: Head gasket?
You remove air filter and other parts.
Then you remove head cover.
Then you unscrew and remove the head,
Clean a bit the block
Screw back the head
Follow head tourqe settings and screw orders on diagrams when mounting back the head.
The whole thing is not thst easy as it may seem, if you want to DIY you will need to buy the Haynes manual for your car. There you find a step by step procedure with pictures.
Here is a repair manual.
Also enquiry to Haynes.Haynes manuals are the best.
Here is how to replace head gasket on a Honda, with lots of pics, procedure is the same, torque values and screwing order are different. It is not a job for absolute beginners

If the idler pulley, broke, with the car running, (I think is the most probable), There is no way to fix the car just replacing the timing belt and the idler pulley. This is an interference engine, that means if the timing belt or the idler pulley breaks, you need to replace the whole cylinder head, that's because the valves are bent. I just fix my daewoo, I tried first to just change the idler pulley and set up the time, but it did not work. I had to replace the whole head cylinder, timing belt and pulleys.
I got the information to set up the timing belt from a Library, The program is Mitchell on demand.

Hello martin09canc: First thing to do is relieve fuel pressure in the fuel system. Remove the rear seat cushion.Remove the access cover. Disconnect the electrical plug.Would not hurt to disconnect the negative battery cable. This would eliminate any sparks. Remove the sender retaining ring. Lift out the sender unit. Be careful not to spill gas on the carpet. Replace the seal and reverse the operation to install new unit. If you need further help please just ask. Please rate the quality of the answer as it also helps. Thank You for using FixYa. Roger

Follow these instructions to the letter, if u get this wrong u will bend the valves in the engine.

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

Your Daewoo has an 2.2L engine and it's an interfernce engine. Which if the timing belt pop it will bent valve's. To align timing mark's both intake and exhaust cam gear's have a mark, on backplate of gear's at 12 o'clock there a mark align both gear's to that. on crankshaft timing belt pulley has a noch on housing back of gear at the 6 o'clock there a v cut, align pulley to that. Good luck
