Est. Time: 30 min

In this guide, you will learn how to remove and replace the serpentine belt (V-ribbed belt) on Hyundai Sonata and Kia Optima equipped with 2.0T and 2.4L, 4-cylinder engine.

What you will need

Procedure

  1. Start by opening the hood on your vehicle. Make sure the engine has cooled down or you risk getting burned.
  2. Look carefully at your old serpentine belt and note how it is routed. Draw a quick sketch if necessary.
  3. Place the 17 mm wrench on the tensioner bolt and turn up the tensioner to release pressure on the belt. Getting to the tensioner bolt is tricky as there isn't too much room. Be careful with the wrench making sure it doesn't slide off the tensioner.
  4. Slide the old belt away from the tensioner and remove it as shown in the following video clip. At this point, you can slowly let the tensioner return so you don't have to keep holding it. Carefully remove the belt from all the pulleys. 
  5. Install the new belt can be tricky. There is very limited space for you to get your new belt around the pulleys. Route the new belt in the same exact way the old serpentine belt was routed. Make sure to insert the V-belt ribs into the pulley grooves.
  6. Ensure the belt is not twisted. Pull-on the tensioner and carefully slide the new serpentine belt in as the last step.
  7. If you fully open the tensioner but still can not install the new belt because it is too short, it is very likely the belt is not fitted properly on the pulleys. Inspect and make sure the belt is sitting properly on all pulleys.
  8. Ensure the belt is routed properly before you start the car. Allow the tensioner to rest on the new belt. how to replace serpentine belt kia optima 2011 20111 2012 2013 2014 2015 2016
  9. Before you start the car double-check the serpentine belt is installed properly.
  10. The belt should be sitting correctly in all the pulleys. Since this is a spring-loaded tensioner you don't need to do any manual adjustment.

NOTES

  • Be cautious as you remove the belt from the tensioner. The belt or tensioner can snap and cause damage to you or your vehicle.
  • Before you install the new belt, spin the tensioner pulley to check it is spinning freely.
  • Use a quality serpentine belt to avoid serpentine belt squeaks and noises.

The serpentine belt drives your alternator, air conditioner compressor, and water pump. It needs to be replaced if it has cracks or makes squeaking noise at start up.
