Are you replacing a broken timing belt? Or are you replacing a belt because it's due by miles? If the belt is broken, i strongly suggest inspecting for bent valves. Daewoo is notorious for bending all valves and breaking valve guides in the cylinder head when the timing belt breaks. The broken belt is also common.

Additionaly if you are interesting, in this link could find the Nubira's manual: Daewoo/Nubira/Nubira%20complet

Hope this helps.

hes right if it has an overhead cam motor

your daewoo does not have an interference engine which means that if timing belt slips or breaks there wont be any valve or piston damage

Yes you should always do the water pump when doing the timing belt. belt tension too tight can cause the break as well as a bad water pump or idler pully, these should all be replaced when you do a timing belt to save yourself this exact headache later on.
