What is specs for setting timing belt on a 1999 daewoo lanos?

When changing a timing belt, getting it EXACTLY RIGHT is CRITICAL.





If you are one tooth out on any of the important gears your engine will not run properly. If you are several teeth out you run the risk of bending the intake and exhaust valves rendering the engine useless.





I'm assuming you know where the timing belt is and how to get to it.





The timing belt runs around several gears these include gears on the crankshaft and on the camshaft. They are the critical ones. It will also run around several idler pulleys, a tensioner and possibly the water pump drive.





There are two types of timing belt alignment systems that I know of. One is where the timing gears and block/head have corresponding marks and the other is the timing gears have marks that line up with marks on the timing belt itself.





System one.





All of the critical gears will have a mark on them, such as an indented dot, raised dot or small arrow. These marks can sometimes be hard to find. Now each of those marks will have a corresponding mark on the block/head. You need to wind the engine over by hand until all these marks line up. Remembering that for every revolution of the crankshaft the camshaft will only do 1/2 a revolution.





Now release the spring loaded tensioner and remove the old belt. The cam shaft gear may move as you release tension as it is under load from the valve springs. You may want to make a wooden wedge to gently tap in between the gear and the head to stop it from moving prior to releasing tensioner..





When replacing the belt it is imperative that all of the marks still line up once the new belt is in place and under correct tension from the spring loaded tensioner. Don't forget to tighten up the tensioner locking bolt.





Now wind the engine over by hand several times and then check for alignment of the marks again remembering the 2 to 1 ratio of the crankshaft to the camshaft. If all marks still line up then you're right to start the engine. Once you're happy that the engine is running correctly replace the covers.





System two.





This system is virtually the same but the marks on the gears must align with the corresponding marks on the timing belt itself. The marks on the timing belt are white lines that run across the belt.





Having said all that I must say proceed at own risk. If you get it right you will save a few hundred dollars by doing it yourself. Get it wrong and you risk destroying your engine.
