Belt Routing

Before you begin any work, take a clear photograph of your current serpentine belt routing. This will serve as an invaluable reference during reinstallation.

The 2019 Ford Escape can come with various engine options, and the belt routing may differ slightly between them. Here's a general guide; always refer to your specific engine diagram if available. For most configurations, the belt typically follows a path similar to this:

1. Starting from the crankshaft pulley at the bottom.
2. The belt will then route up and over the A/C compressor pulley.
3. From the A/C compressor, the belt often goes to an idler pulley (or multiple idler pulleys, depending on the engine).
4. From the idler pulley, it will go to the alternator pulley.
5. Next, the belt may route to the power steering pump pulley (if equipped and not electrically assisted).
6. It then typically goes around the water pump pulley.
7. Finally, the belt routes to the automatic tensioner pulley, which maintains the proper tension on the belt.

How to Replace the Serpentine Belt

Replacing the serpentine belt on your 2019 Ford Escape is a manageable DIY job for those with some mechanical experience. You'll primarily need a serpentine belt tool or a 3/8" drive breaker bar to release the tension on the automatic belt tensioner.

1. Safety First: Ensure the engine is off and cool. Disconnect the negative terminal of your battery for added safety.
2. Locate the Tensioner: Identify the automatic belt tensioner. It will have a square hole designed to accept a 3/8" drive ratchet or a serpentine belt tool.
3. Release Tension: Insert your tool into the tensioner's square hole and rotate it to relieve the tension on the belt. While holding the tensioner in the released position, carefully slip the old belt off one of the pulleys.
4. Remove Old Belt: Once some slack is created, you can completely remove the old belt from all pulleys.
5. Route New Belt: Following your photograph and the routing description, carefully route the new serpentine belt around all the pulleys, leaving the tensioner pulley for last or a pulley that offers easy access to slip the belt on.
6. Install on Tensioner: With the belt mostly routed, again apply pressure to the tensioner with your tool, and slip the belt over the final pulley.
7. Inspect: Once the belt is in place, slowly release the tensioner and ensure the belt is properly seated in all the grooves of every pulley. Double-check your routing against your photograph.
8. Reconnect Battery: Reconnect the negative battery terminal.
9. Test: Start the engine and listen for any abnormal noises. Visually inspect the belt to ensure it's running smoothly and correctly.

Replacement Interval

Serpentine belts on modern vehicles like the 2019 Ford Escape are designed for longevity. However, they are still wear items. It's generally recommended to inspect your serpentine belt at every oil change or at least once a year. Most manufacturers recommend replacement between 60,000 to 100,000 miles, or every 5-7 years, whichever comes first. Always consult your owner's manual for the most accurate and manufacturer-specific recommendations for your particular engine.

Signs of a Failing Belt or Tensioner

Ignored serpentine belt or tensioner issues can lead to loss of power steering (if hydraulic), A/C, and charging system operation, potentially stranding you. Be alert for these warning signs:

• Squealing or Chirping Noises: This is one of the most common signs of a worn or misaligned belt, or a failing tensioner/pulley bearing. The noise may be more prominent on cold starts or when the engine is under load.
• Cracks, Fraying, or Glazing on the Belt: Visually inspect the belt for any signs of wear. Small cracks across the ribs are normal with age, but deep cracks, missing chunks, or fraying edges indicate it's time for replacement. A shiny, glazed appearance on the belt can indicate slippage.
• Loss of Power Steering, A/C, or Battery Charging: If the belt slips or breaks, these engine accessories will stop working. A completely broken belt will result in total loss of these functions.
• Vibrations or Wobbling in the Tensioner or Idler Pulleys: Worn bearings in the tensioner or idler pulleys can cause them to wobble or vibrate excessively. This often accompanies squealing noises.
• Tensioner Not Maintaining Proper Tension: The tensioner should maintain consistent tension. If it appears weak, or if the belt seems unusually loose, the tensioner may be failing.
• Growling or Grinding Noises: These sounds, often originating from a pulley, can indicate a failing bearing within the tensioner or an idler pulley.

Engine-Specific Variations

It's crucial to note that serpentine belt and tensioner part numbers, as well as specific routing, can vary significantly depending on the engine size and configuration in your 2019 Ford Escape. For instance, a 1.5L EcoBoost engine will likely have different parts and potentially a different routing than a 2.0L EcoBoost or a 2.5L engine. Always verify part numbers with a reputable parts supplier or your Ford dealership using your VIN to ensure correct fitment.
