Rio Timing belt problems
By mttom on
Vehicle
2004 Kia Rio 4dr Sedan (1.6L 4cyl 5M)
Review
I'm tearing down a 2004 Kia Rio with 32000 miles, well cared for, Not Abused, fresh oil change and Fram filter, LOCKED engine, failed timing belt, At first I thought inferior quality belt and poor components, but this is a rugged copy of the Mazda which can run many miles, everything looks great but the belt is hard and not very flexible. Maybe Kia scrimped on this but I really doubt it, seems like a heat problem so I did a closer look. To keep engine noise to an absolute minimum, the hood is heavily insulated as well as a plastic cover plate over the engine, But in addition to that Both fenders and the firewall have a continuous rubber gasket as does most of the front of the hood,
Suggested Improvements
As a result the heat from the exhaust manifold, catolitic converter and the engine head are all captured and held inside unless of course your driving real fast. The design to keep the engine quiet is destroying components under the hood

I have completed repairing this car luckily broken valve didn't break piston, now runs great. I stripped off the side strips up to the hinge assembly, also got rid of the engine cover/insulation. The timing belt was a high quality Bando, replaced it with a Dayco, again HEAT is sealed into this engine, NO other manufacturer I have seen uses a seal around the hood, get rid of them and the Kia will run along time.
