There is a Problem with the Kia Belts. Just got a 2004 Kia Rio, 32,000 Actual Miles, nice clean well cared for. BROKEN TIMING BELT!, No no warranty since you are supposed to replace the belt at 5 years time regardless of miles. The belt lost teeth, what usually happens, locking up the engine. Am in the process of tearing it down. The belt is hard, not very flexible, doubt it has high saturated nitrates for heat, as the Dayco, Gates, and Goodyear belts do, the bond between the cogs and belt obviously broke down. I have worked on cars for years, remember the Chrysler K cars, saw many with 150,000 miles not a bolt touched and yes they had a rubber timing belt. This is a copy of a Mazda engine, which also uses rubber belts and they last far longer than this. IF you have one of these CHANGE the belt, as to using a KIA belt, Very sure Hyundia has switched the design, manufacturer, and IT IS NOT the same belt. As of 2006 the Rio is really a Hyundia Accent different engine, and belt. Dayco Gates, Goodyear and other major makers MAKE quality products, mechanics wouldn't buy them if they weren't. Used engines for this car are over $2000 plus installation, as they are impossible to find and GOLD to a wrecking yard. This should tell everyone THERE is a PROBLEM. If this engine is completely gone then the car will be scrapped, it is currently at a wrecking yard.
