2017 Ford Escape serpentine belt diagram with routing details and pulley positions
To replace the serpentine belt on a 2017 Ford Escape with a 1.5L EcoBoost engine, route the new belt following a specific path: crankshaft pulley → A/C compressor → tensioner → alternator → idler pulley → water pump. Always double-check this path against the diagram under the hood or the official service manual before installation.
The belt tensioner is spring-loaded and requires a 15mm wrench or serpentine belt tool to rotate. Turn the tensioner clockwise to relieve tension, remove the old belt, and install the new one along the correct pulleys. Ensure the grooves on the belt align perfectly with each ribbed pulley surface to avoid misalignment or premature wear.
Engines equipped with the 2.0L or 2.5L variants use slightly different routing patterns, especially if the vehicle includes additional accessories like power steering or a secondary idler. Always verify engine type before selecting a belt diagram. Incorrect routing can lead to noise, overheating, or accessory failure.
Inspect the belt for cracks, fraying, or glazing every 60,000 miles. If any signs of wear are present, replace the belt immediately to avoid unexpected breakdowns. Use only belts that match OEM specifications for length and rib count to maintain proper function and tension across all components.
2017 Ford Escape Serpentine Belt Diagram
Use the correct routing to avoid tension issues or accessory failure. For the 2017 Ford Escape with the 1.5L EcoBoost engine, the serpentine belt loops around the following components in this sequence: starting at the crankshaft pulley, it wraps clockwise around the A/C compressor, continues to the idler pulley, then around the alternator, over the water pump, and finally under the tensioner pulley.
On the 2.0L EcoBoost, the layout differs slightly. The belt starts at the crankshaft, moves under the water pump, wraps over the alternator, goes around the idler, continues to the A/C compressor, and finishes over the automatic tensioner. Always double-check the pulley diameters and orientation before reinstallation.
Before removing the belt, take a clear photo or sketch the current routing. Use a 15mm wrench on the tensioner to relieve pressure, rotate counterclockwise, and slide the belt off. Inspect pulleys for wobble or noise, and replace the belt if it shows cracks, glazing, or fraying along the edges.
A factory-style diagram is usually located on the radiator support or underside of the hood. If it’s missing, refer to the service manual or use a verified repair database specific to the engine type.
How to Locate and Identify the Serpentine Belt on a 2017 Ford Escape
Open the hood and focus your attention on the passenger side of the engine bay. On the 2017 Ford Escape, the serpentine belt is mounted on the front of the engine block, which faces sideways due to the transverse engine layout.
The belt wraps around multiple pulleys including the alternator, A/C compressor, water pump, power steering pump (if equipped), and the crankshaft pulley. Look for a wide black rubber belt with visible grooves running along the pulley system.
Use the following steps to identify the belt quickly:
- Locate the plastic engine cover and remove it if necessary by pulling upward gently. Some trims may not require removal.
- Find the largest pulley at the bottom – this is the crankshaft pulley. The belt loops around this and drives the rest of the components.
- Trace the belt upward and to the left to find the alternator. The alternator pulley usually sits higher and toward the rear of the engine bay.
- Look toward the front of the engine for the A/C compressor pulley – often lower and slightly hidden behind the frame.
- The tensioner pulley is spring-loaded and typically smooth. It’s mounted on a bracket and may be positioned near the top or middle, depending on the engine type (1.5L, 2.0L, or 2.5L).
For better visibility, use a flashlight and inspect the belt from the passenger-side wheel well by turning the wheel outward and removing the splash shield if needed. This gives access to the lower pulleys and helps verify routing if you’re replacing the belt.
A belt routing diagram is usually found on a sticker near the radiator support or the underside of the hood. If missing, consult the service manual or take a photo before removing the belt.
Steps to Remove and Replace the Serpentine Belt Without Special Tools
Use a standard 15mm wrench to rotate the tensioner pulley clockwise. This will release tension from the serpentine belt. Hold the tensioner in this position while sliding the belt off one of the pulleys, usually the alternator or idler pulley for easiest access.
Before removing the old belt completely, take a clear photo of the belt routing or refer to the diagram located on the radiator support. This will help during reinstallation. Remove the belt from all pulleys and check for cracks, fraying, or glazing. Discard if worn.
Route the new belt around the crankshaft, A/C compressor, water pump, and power steering pump according to the diagram. Leave the alternator or idler pulley for last. Hold the tensioner with the 15mm wrench again, rotate it, and slip the belt over the final pulley. Slowly release the tensioner to apply pressure to the belt.
Check belt alignment on all pulleys. Misalignment can cause noise or premature wear. Rotate the crankshaft manually with a socket wrench to ensure the belt tracks properly and doesn’t slip. Reconnect the negative battery cable if it was removed.
Belt Routing Diagram Differences Between 1.5L, 2.0L, and 2.5L Engines
Identify the engine type before referencing any diagram. The 1.5L EcoBoost uses a serpentine belt routed around the crankshaft pulley, alternator, A/C compressor, and tensioner. The water pump is driven by this belt, and the tensioner sits just below the alternator on the passenger side.
The 2.0L EcoBoost differs by excluding the water pump from the serpentine system, as it runs off the timing belt. The serpentine belt wraps around the crankshaft, alternator, A/C compressor, and tensioner, but follows a tighter, more compact path. The tensioner mounts slightly lower and closer to the crankshaft than on the 1.5L.
The 2.5L naturally aspirated engine features a different layout. The belt drives the alternator, A/C compressor, and power steering pump. The tensioner is located higher, above the crankshaft pulley. The routing is more vertical and does not include the water pump, which is internally driven.
Use the label under the hood or the factory service manual to match the routing to the correct engine variant. Incorrect routing can misalign pulleys and overload components.
