2016 Ford Fusion Serpentine Belt Diagram and Routing Guide

The 2016 Ford Fusion uses a serpentine belt system that powers various engine components. To replace or troubleshoot the belt, it’s important to understand the proper routing and components involved.
Start by checking the belt tensioner. A worn or damaged tensioner can lead to improper belt alignment, causing slippage or even breakage. If the tensioner is functioning well, inspect the belt for wear, cracks, or fraying. If any of these issues are found, it’s time to replace the belt.
Use the diagram provided to ensure proper routing. The serpentine belt must be threaded through the pulleys in a specific order to prevent engine damage. Follow the steps closely and ensure all components align as per the diagram to avoid complications.
2016 Ford Fusion Belt Diagram
The 2016 Ford Fusion is equipped with a serpentine belt that powers multiple accessories, including the alternator, air conditioning, and power steering pump. To ensure proper function, it’s important to follow the correct routing for the belt. The diagram for the 2016 Ford Fusion shows the belt routing around various pulleys and components. Make sure the belt is tensioned correctly to avoid slipping or damage to the components it drives.
When replacing the serpentine belt, start by removing any components that may obstruct access to the belt. Use a belt tensioner tool to relieve tension from the belt, then remove it from the pulleys. Compare the old belt with the new one to ensure it matches in size and pattern. Install the new belt by following the routing path shown in the diagram, and ensure it sits properly in the grooves of each pulley. Once installed, check the tension and alignment before starting the engine.
It is recommended to inspect the belt for signs of wear, such as cracks or fraying, every 30,000 miles. If the belt shows any damage, replace it immediately to avoid potential engine damage or loss of accessory power. Proper maintenance and correct installation will help extend the life of the belt and maintain the performance of your 2016 Ford Fusion.
How to Read the 2016 Ford Fusion Belt Diagram
Start by identifying the key components in the diagram: the serpentine belt, pulleys, tensioner, and accessories. The diagram typically shows the route the belt takes, including how it loops around various pulleys. Understanding the sequence of these components helps ensure the correct belt installation.
Follow the diagram’s path, paying close attention to the direction of the pulleys and the path the belt travels. The arrows in the diagram show how the belt wraps around each pulley. Some diagrams may include specific instructions on the routing for the automatic tensioner or how to adjust the tension once the new belt is installed.
Note the orientation of the pulleys. Most diagrams show which pulleys are driven by the belt and whether the pulley is idle or actively driven by the engine. The diagram may also mark specific pulleys for components like the alternator, air conditioning compressor, or power steering pump.
Before replacing the belt, compare the diagram with the actual setup in your engine bay to ensure accuracy. If any discrepancies are found, double-check the diagram or consult your vehicle’s manual for further clarification.
Finally, after installing the belt, refer back to the diagram to confirm proper routing and to ensure all components are aligned correctly for optimal performance.
Common Belt Issues in the 2016 Ford Fusion and How to Fix Them
If you’re experiencing issues with the belts in your 2016 Ford Fusion, there are a few common problems to be aware of. These include slipping belts, squeaking noises, and worn-out belts that can cause poor performance or even engine damage. Here’s how to diagnose and fix them.
Slipping Belt: A slipping belt can cause poor performance in various vehicle systems, such as the alternator or air conditioning. This usually occurs when the belt becomes too loose. To fix this, check the belt tension. If it’s loose, tighten the tensioner or replace it if worn. If the belt itself appears worn or cracked, replacing it is recommended.
Squeaking Noises: If you hear squeaking or chirping sounds, it’s often due to a worn-out or misaligned belt. This can happen from age or if the belt isn’t seated properly. Inspect the belt for visible cracks or signs of wear, and replace it if necessary. Additionally, check for any misalignment of pulleys and adjust them as needed.
Belt Wear and Cracking: Over time, the rubber in the belt can dry out and crack, causing it to lose its grip on pulleys. This can lead to slipping or even belt failure. Regularly inspect the belt for cracks, fraying, or wear. If any of these signs are present, replacing the belt will prevent more serious issues down the road.
Worn Pulley or Tensioner: Sometimes the problem isn’t with the belt itself but with the components that keep it tight. A faulty tensioner or pulley can cause the belt to slip or wear out prematurely. If the tensioner isn’t maintaining the correct pressure or the pulley has become misaligned, replace the faulty component and inspect the belt for damage.
Damaged or Broken Belt: If your belt is completely broken or severely damaged, replace it immediately. Driving without a belt can lead to further engine damage. Be sure to replace the belt with the proper size and ensure that all components are functioning properly before reinstalling the new belt.
Steps to Replace the Serpentine Belt on a 2016 Ford Fusion

Start by locating the serpentine belt tensioner, which is near the front of the engine, typically on the passenger side. Use a socket wrench to rotate the tensioner and relieve tension from the belt.
Once the tension is released, carefully remove the belt from the pulleys. Pay attention to the routing of the belt, as you will need to follow the exact pattern when installing the new one. Take note of the belt’s orientation or refer to the owner’s manual for the diagram.
Before installing the new serpentine belt, check all pulleys for wear or damage. Spin them by hand to ensure they rotate freely and do not show signs of friction or unusual noise. Replace any worn-out pulleys or tensioners as needed.
Install the new serpentine belt by following the routing diagram. Begin by placing the belt around the pulleys, ensuring it is seated properly on each one. Be careful not to twist or force the belt into place.
Once the belt is correctly installed, use the socket wrench to rotate the tensioner again and allow the tensioner to hold the belt in place. Double-check the belt’s alignment on all pulleys.
Start the engine and observe the belt in motion. Ensure it runs smoothly and does not slip or make unusual noises. If there are any issues, turn off the engine and adjust the belt or tensioner as necessary.
