timing belt

It has a timing chain. No regular service required. Zee

80.000 miles

I have a 2005 KIA Sodona van with a 3.5 Lit. They recommend to swap out at 60,000 miles. I did mine a 86,000 at that time I chaned all belts and water pump. I don't recommend going out over 90,000 before doing this, but that depends on alot of things, The way you drive and maintain the auto and luck.
