If you own a Subaru, it is important to regularly check and replace the stretch belt. A stretch belt, also known as a serpentine belt, is an essential part of your car’s engine that powers the alternator, air conditioning, power steering, and water pump. Over time, the belt can become worn or damaged, which can lead to serious engine problems. In this article, we will provide a step-by-step guide on how to put on a stretch belt for your Subaru, including the tools you will need and key tips to ensure a smooth process.

Key Takeaways

  • Regularly check and replace your stretch belt to avoid engine problems.
  • Use the appropriate tools, including a socket wrench and belt tensioner tool.
  • Follow the manufacturer’s instructions and diagrams carefully.
  • Check the belt tension after installation to ensure proper fit.

Tools and Equipment Required

Before starting the installation process, it is important to gather all the necessary tools and equipment. Here’s what you’ll need:

  • Socket wrench with appropriate socket size
  • Belt tensioner tool
  • Replacement stretch belt for your Subaru
  • Owner’s manual or online instructions for your specific model of Subaru

Step-by-Step Instructions

  1. Locate the stretch belt in your Subaru. It should be located at the front of the engine and will be wrapped around several pulleys, including the alternator, air conditioning compressor, power steering pump, and water pump.

  2. Refer to the owner’s manual or online instructions for your specific model of Subaru to determine the correct size and type of replacement stretch belt you need. This information should also include a diagram of the belt’s routing pattern.

  3. Use a socket wrench to loosen the tensioner pulley, which will release the old belt. Be sure to remember the belt’s routing pattern before removing it so you can install the replacement belt correctly.

  4. Install the new stretch belt by following the routing pattern shown in the diagram provided by the manufacturer. Use the belt tensioner tool to adjust the tension, ensuring a snug fit without over-tightening.

  5. Once the new belt is in place, check the tension by pressing on it firmly with your finger. It should give about half an inch when pressure is applied.

  6. Start the engine and let it run for a few minutes to check for any unusual sounds or vibrations. If there are no issues, you have successfully installed your new stretch belt.
