You fail to list what model Kia and what engine. The only 1999 KIA that has a chain is the Sephia with the 1.8L engine. This is an INTERFERENCE engine and as such, if the belt breaks, serious engine damage will occur. The belt must be replaced every 60,000 miles, except California models which is every 100,000 miles.
