2017 Kia Soul Serpentine Belt Diagram and Routing Guide

To replace or inspect the serpentine belt on a 2017 Kia Soul, it’s vital to understand the belt routing diagram. This diagram indicates the correct path the serpentine belt follows over the various pulleys and components within the engine. Ensure you have the correct diagram for your specific model to avoid issues with installation or performance.
The serpentine belt on the 2017 Kia Soul is essential for driving multiple components like the alternator, air conditioning compressor, power steering pump, and water pump. It’s important to check for any signs of wear, such as cracking, fraying, or noise during operation, as these may signal the need for replacement.
Before starting, disconnect the negative terminal from the battery to ensure safety while working around the engine. Use a belt tensioner tool to release tension from the belt before removal. Once removed, check the tensioner, pulleys, and other components for damage or excessive wear. Install the new serpentine belt by following the routing diagram precisely, and ensure the belt sits properly on all pulleys.
2017 Kia Soul Serpentine Belt Diagram

The serpentine belt in your 2017 Kia Soul plays a key role in driving essential components like the alternator, power steering pump, and air conditioning compressor. Understanding its layout is crucial for maintenance or replacement. Here’s the breakdown of the serpentine belt path for this model:
- The belt routes around the crankshaft pulley, powering the engine accessories.
- The alternator is driven from the serpentine belt, providing power to the electrical system.
- The power steering pump is also powered by the belt, ensuring smooth steering operation.
- The air conditioning compressor relies on the belt to maintain cabin cooling.
- The tensioner pulley keeps the serpentine belt tight, ensuring it doesn’t slip off during operation.
To ensure smooth operation, always inspect the belt for wear and damage. If you notice cracking, fraying, or glazing, it may be time for a replacement. Be sure to follow the diagram carefully when installing a new serpentine belt to prevent improper routing that could damage components.
How to Identify Components in the 2017 Kia Soul Serpentine Belt System
To identify the components of the serpentine belt system in your 2017 Kia Soul, begin by locating the serpentine belt itself. The belt runs along various pulleys and is driven by the engine crankshaft pulley. Start with the belt tensioner, which maintains proper tension on the belt. This component is typically a spring-loaded pulley, and it is important to inspect it for any signs of wear or damage.
Next, locate the idler pulley. It helps guide the belt in the right direction and supports its movement. The idler pulley typically does not provide any drive power to other components but ensures the belt remains in place. Check for any unusual noises or resistance when turning the pulley manually.
The alternator is another crucial component in the serpentine system. It is driven by the belt and generates electrical power for the vehicle. Inspect the alternator pulley for any signs of corrosion or damage. If the alternator is not functioning properly, the serpentine belt may need to be replaced or realigned.
Other components powered by the serpentine belt include the power steering pump and the air conditioning compressor. Inspect these pulleys for smooth operation and ensure there are no oil leaks around the components. The belt should fit snugly over each pulley without excessive slack or tension.
Finally, check the crankshaft pulley, which is typically located at the bottom of the engine. This component drives the serpentine belt and is crucial for proper system operation. Ensure it is secure and free of any damage, as any issue here could impact the entire serpentine belt system.
Steps to Replace the Serpentine Belt on a 2017 Kia Soul

Begin by ensuring the engine is turned off and the car is parked on a flat surface. Engage the parking brake for added safety.
Locate the serpentine belt tensioner. Use a wrench or ratchet to relieve tension on the belt. Rotate the tensioner clockwise to release the belt from the pulley system.
Carefully remove the old serpentine belt from the pulleys. Make note of the routing diagram or refer to the vehicle’s manual to ensure correct installation of the new belt.
Install the new serpentine belt by following the routing path. Start by placing the belt around the pulleys one at a time, making sure it sits securely in each groove.
Once the belt is in place, use the wrench or ratchet to rotate the tensioner again, allowing the new belt to fit tightly in the system.
Double-check that the belt is properly aligned on all pulleys. Spin the belt by hand to ensure smooth movement and that it’s seated correctly.
Start the engine and observe the belt in operation to confirm it runs smoothly without any slippage or unusual sounds.
Troubleshooting Common Serpentine Belt Issues on a 2017 Kia Soul
If you notice any unusual noises or performance issues, the serpentine belt may be the culprit. A slipping or worn-out belt can lead to power steering failure, overheating, or electrical issues.
First, check the belt for visible signs of wear, such as cracks, fraying, or glazing. If any damage is present, replace the belt immediately. A loose belt can cause squealing noises, so check the tension as well. Use a tension gauge to ensure the proper tension is maintained.
Next, inspect the pulleys and idler arms. A misaligned pulley can cause the belt to slip, leading to premature wear. Rotate each pulley by hand to check for smooth operation and ensure no wobbling or excessive resistance.
Lastly, consider the age of the belt. If it has been in place for over 60,000 miles, replacing it as part of regular maintenance is a good practice, even if no visible damage is present. Routine checks help prevent unexpected breakdowns.
