How much would it cost to get the cylinder head fixed on a 2000 Daewoo Leganza?

it would depend on what was wrong with it,if its a gasket a few hundred at least if it has a cracked head a lot,you,ll have to get it diagnosed before anyone can give a real good answer on it.good luck with it|||Another driver that did not know to change that cheap Korean timing belt before 60k.. The cost depends on how much damage was done to the valves.. $1000-$2500 or so. Sorry someone did not tell you before. A timing belt change before it breaks is like $150-$250.
