2013 Ford Explorer 2.0 EcoBoost Serpentine Belt Diagram and Routing

The serpentine belt diagram for the 2013 Ford Explorer 2.0 EcoBoost is an important reference when replacing or inspecting the belt. Follow this diagram closely to avoid misalignment or damage. The serpentine belt drives multiple engine components like the alternator, power steering pump, and air conditioning compressor. Incorrect routing can lead to premature wear and poor engine performance.
To install or replace the serpentine belt, start by releasing the tension on the belt using the tensioner pulley. The diagram indicates the exact path the belt should take around each component. Check for any signs of wear, such as cracks or fraying, which can indicate that the belt needs to be replaced. Ensure the belt is properly aligned with all pulleys before applying tension.
Once the new belt is in place, check the routing one last time to make sure it matches the diagram. The belt should sit evenly on all pulleys without slack or tight spots. Proper installation ensures that the system runs smoothly and reduces the risk of overheating or part failure due to incorrect belt tension.
2013 Ford Explorer 2.0 EcoBoost Belt Diagram

For the 2013 Ford Explorer 2.0 EcoBoost, the serpentine belt routing is key for smooth engine operation. To replace or inspect the serpentine belt, start by ensuring the engine is off and cool. Locate the tensioner pulley, which controls belt tension, and use a suitable tool to release its pressure. Carefully remove the old belt, making sure not to damage surrounding components.
Refer to the diagram for accurate routing, noting the positions of the alternator, power steering pump, air conditioning compressor, and other pulleys. Route the new belt as shown, ensuring it fits snugly in each groove. Double-check the alignment with the pulleys before releasing the tensioner and securing the belt. Verify the belt runs smoothly before starting the engine to test for proper operation.
Check the belt periodically for wear and replace it every 60,000 to 100,000 miles or as specified in the vehicle’s manual. If you hear unusual noises or notice visible cracks, replace the belt promptly to prevent further damage to the engine components.
How to Identify the Serpentine Belt Components on 2013 Ford Explorer
Inspect the serpentine belt components of the 2013 Ford Explorer to ensure all parts are functioning properly and in place. Start by locating the belt routing diagram, which is usually found on the radiator support or near the front of the engine compartment. This diagram will serve as a visual reference for identifying the belt’s path and the various components involved.
Here’s a breakdown of the components to look for:
- Serpentine Belt: This is the long, continuous belt that drives multiple engine accessories. It should be in good condition without visible cracks or wear.
- Belt Tensioner: Located near the center of the belt path, the tensioner keeps the belt tight. Look for a spring-loaded component with a pulley attached to it. It should move smoothly when manually adjusted.
- Idler Pulley: Typically situated at the top of the engine, this pulley supports the belt without driving any accessories. It should be free of rust and debris, and rotate smoothly without any unusual noise.
- Alternator Pulley: This pulley drives the alternator and is generally found near the top of the engine. Check for any signs of damage or wear, such as uneven wear patterns on the belt.
- Power Steering Pulley: Found near the alternator, this pulley drives the power steering pump. Ensure the pulley is aligned properly with the rest of the system.
- Air Conditioning Pulley: Positioned near the power steering pulley, this component drives the air conditioning compressor. Look for any abnormal sounds when the system is engaged.
After identifying the components, check for proper alignment. If the belt appears misaligned or damaged, it may need to be replaced. Ensure that the tensioner is maintaining the right amount of tension to prevent slipping or excessive wear.
Steps to Properly Route the Serpentine Belt on 2013 Ford Explorer

Begin by identifying the routing diagram for the serpentine belt. It is typically located on the radiator support or near the engine bay. Use this diagram as a reference throughout the process.
Next, ensure the belt tensioner is released. This is usually done by turning the tensioner pulley clockwise using a wrench. Once the tension is released, carefully remove the old belt.
Start routing the new serpentine belt by placing it around the crankshaft pulley. Then move it towards the alternator pulley, making sure the belt is seated properly in the grooves.
Continue routing the belt over the power steering pump, the air conditioning compressor, and other components following the diagram. Each pulley must align with the belt’s grooves to prevent slipping or misalignment.
Once the belt is routed, double-check its positioning. Ensure it is correctly seated on all pulleys and that the belt tensioner is functioning as expected. Reapply tension to the belt by turning the tensioner pulley counterclockwise until it locks in place.
Finally, inspect the belt for proper alignment and tightness before starting the engine. Start the vehicle and listen for any unusual noises that may indicate improper routing.
How to Replace the Serpentine Belt Tensioner on 2013 Ford Explorer
To replace the serpentine belt tensioner on a 2013 Ford Explorer, begin by disconnecting the vehicle’s battery to ensure safety. Use a socket wrench to remove any components obstructing access to the tensioner, such as the air intake or other engine covers. Once accessible, locate the tensioner on the front of the engine, usually near the bottom right side of the engine block.
Next, use a serpentine belt tool or a ratchet wrench to relieve the tension on the belt. Rotate the tensioner counterclockwise to release the belt, and carefully remove the belt from the pulleys. Take note of the routing before removing the belt to assist in reinstallation.
Remove the bolts securing the tensioner to the engine bracket. It may require a deep socket or wrench to access the bolts. Once the tensioner is removed, compare the new part with the old one to ensure they are identical. Install the new tensioner by aligning it with the mounting holes and securing it with the bolts.
After the new tensioner is in place, reinstall the serpentine belt by following the same routing as the old belt. Use the serpentine belt tool or ratchet wrench to apply tension to the new belt by rotating the tensioner clockwise. Double-check that the belt sits properly on all pulleys.
Finally, reassemble any parts you removed, reconnect the battery, and start the engine to ensure proper operation of the new tensioner and belt. Check the tensioner for any abnormal noise or movement to confirm it’s functioning correctly.
