The serpentine belt in a 2017 Hyundai Sonata is crucial for driving various engine accessories, including the alternator, air conditioning compressor, and water pump. Understanding how to replace this belt and its routing can help maintain your vehicle's performance.

Serpentine Belt Diagram

The serpentine belt routing for the 2017 Hyundai Sonata typically follows this path:

  • Crankshaft Pulley: The belt starts at the crankshaft pulley.
  • Tensioner Pulley: It runs to the tensioner pulley, which maintains the belt's tightness.
  • A/C Compressor: From the tensioner, it goes to the A/C compressor.
  • Alternator: The belt then wraps around the alternator.
  • Idler Pulleys: Finally, it returns to the crankshaft pulley via idler pulleys.

This configuration ensures that all necessary components are powered efficiently.

Replacement Procedure

To replace the serpentine belt in your Hyundai Sonata, follow these steps:

1. Disconnect the Battery: Always start by disconnecting the negative battery terminal to avoid any electrical issues.

2. Loosen the Tensioner: Use a 17mm wrench on the tensioner pulley bolt. Rotate it counter-clockwise to relieve tension on the belt.

3. Remove the Old Belt: Once the tension is released, carefully slide the old belt off all pulleys.

4. Install the New Belt: Route the new serpentine belt according to the diagram. Ensure it fits snugly in all grooves of each pulley.

5. Reapply Tension: Rotate the tensioner back into position to secure the new belt.

6. Reconnect Battery: Finally, reconnect the negative battery terminal and start your engine to check for proper operation.

Important Tips

  • Always check for wear on both the serpentine belt and tensioner pulley during replacement.
  • Ensure that the new belt is properly seated in all grooves to prevent slippage or damage.
  • If you're unsure about routing, take a picture of the old belt before removal or consult a repair manual for guidance.
