Belt Diagram for 5.7 Hemi


The 5.7 Hemi engine is a powerful and popular option in many vehicles, known for its performance and reliability. One important aspect of maintaining a 5.7 Hemi engine is ensuring the correct belt routing. The belt plays a crucial role in powering various components of the engine, such as the alternator, water pump, power steering pump, and air conditioning compressor. In this article, we will provide a detailed belt diagram for the 5.7 Hemi engine, along with some useful tips for belt replacement and maintenance.

Understanding the Belt Routing

Before diving into the belt diagram, it's important to have a basic understanding of how the belt is routed in a 5.7 Hemi engine. The belt follows a specific path, wrapping around various pulleys to transfer power from the engine crankshaft to the different components. It's crucial to ensure that the belt is correctly aligned and tensioned to prevent any slippage or damage to the engine.

Components Driven by the Belt

The 5.7 Hemi engine typically drives several components using a single serpentine belt. These components include:

  • Alternator
  • Water Pump
  • Power Steering Pump
  • Air Conditioning Compressor
  • Tensioner Pulley

Replacing the Belt

Over time, the belt in a 5.7 Hemi engine can wear out and become damaged. It's important to replace the belt as soon as you notice any signs of wear, such as cracking, fraying, or squealing noise. Here are the steps to replace the belt:

  1. Locate the belt tensioner pulley and use a wrench or socket to release the tension on the belt.
  2. Slide the belt off the pulleys, ensuring to note the correct routing.
  3. Compare the old belt with the new one to ensure the same length and width.
  4. Begin routing the new belt according to the belt diagram, ensuring it is properly aligned with each pulley.
  5. Use the tensioner pulley to release tension on the belt and slide it onto the last pulley.
  6. Double-check the belt routing to ensure it matches the diagram and is properly tensioned.

Belt Tensioning

Proper tensioning of the belt is crucial to prevent slippage and ensure optimal performance. Here are some tips for correctly tensioning the belt:

  • Refer to the vehicle manufacturer's specifications for the correct tensioning procedure.
  • Use a belt tension gauge to ensure the proper tension is applied.
  • A correctly tensioned belt should have a slight deflection when pressed with moderate force.
  • Ensure all pulleys are aligned and free from any debris or damage that may affect belt tension.

Regular Belt Inspection

Regularly inspecting the belt is essential for identifying any signs of wear or damage. Here are some tips for conducting a belt inspection:

  • Check for any cracks, fraying, or signs of stretching on the belt.
  • Listen for any squealing or chirping noises, which may indicate a loose or worn-out belt.
  • Inspect the pulleys for any signs of damage or misalignment.
  • Replace the belt if any signs of wear or damage are detected.


The correct belt routing is essential for the proper functioning and longevity of a 5.7 Hemi engine. By following the provided belt diagram and implementing the tips mentioned in this article, you can ensure that your engine's belt is correctly aligned, tensioned, and in good condition. Regular maintenance and inspection of the belt will help prevent any potential issues and keep your 5.7 Hemi engine running smoothly for years to come.
