For the 2010 Kia Soul, there is one belt—the serpentine belt—that drives all the accessory components. The engine uses a timing chain rather than a belt, so there isn't a separate timing belt in the system.
Belt configuration on the 2010 Soul
Across the available engines in 2010 (typically the 2.0-liter and, in some trims, a 2.4-liter four-cylinder), Kia used a single serpentine belt. This belt powers the alternator, power steering pump, and air conditioning compressor; the timing mechanism is handled by a chain inside the engine, not a belt. Because of that design, owners generally replace only one belt during routine maintenance, rather than a timing belt replacement.
What this means for maintenance and replacement
When inspecting or replacing belts, you will be dealing with the serpentine belt and possibly the belt tensioner or idler pulley if they show wear. Timing chains (not belts) typically do not have a replacement interval the way a timing belt does, but you should follow Kia's maintenance schedule and have any noise or slippage checked promptly.
Notes on model variations
While the exact engine options can vary by trim and market, the belt arrangement for the 2010 Kia Soul has consistently been a single serpentine belt with the timing chain hidden inside the engine. If you are unsure of your specific engine code or belt routing, consult the owner's manual or a service manual for your VIN.
Summary
In summary, a 2010 Kia Soul uses one belt—the serpentine belt—for accessories, with timing controlled by a chain inside the engine. No additional timing belt exists on this model year.
