2023 Ford Explorer Serpentine Belt: Routing, Replacement, & Part Numbers

Quick Answer

For the 2023 Ford Explorer with the 2.3L EcoBoost engine, the common serpentine belt specifications are:

• Belt Length: Approximately 1655mm (65.16 inches)
• Rib Count: 6-rib
• OEM Belt PN: Ford Motorcraft JK6-651 (may vary, always verify with your VIN)
• Aftermarket Cross-References:
  • Gates K060652 (or similar, depending on exact length)
  • Dayco 5060652 (or similar)
  • Continental Elite 4060652 (or similar)
• Auto-Tensioner PN: Ford Motorcraft YS-383 (or similar, always verify)
• Idler Pulley PN: Ford Motorcraft YS-370 (or similar, always verify)

Note: Specifications can vary based on specific engine options (2.3L EcoBoost, 3.0L EcoBoost, 3.3L V6 Hybrid) and vehicle trim levels. Always verify part numbers with your vehicle's VIN to ensure compatibility.

Belt Routing (2.3L EcoBoost Example)

Understanding the serpentine belt routing is crucial before attempting removal or installation. Since we cannot provide a visual diagram, we recommend taking a clear photograph of your existing belt's routing before you begin any work. This will serve as an invaluable reference. For the 2.3L EcoBoost engine in the 2023 Ford Explorer, a common routing path is as follows:

1. Crankshaft Pulley: The belt typically starts at the lowest, largest pulley – the crankshaft pulley, which drives all other accessories.
2. A/C Compressor: From the crankshaft, the belt usually routes up and to the right (when facing the engine from the front of the vehicle) to the air conditioning (A/C) compressor pulley.
3. Idler Pulley: The belt will then often route over a smooth idler pulley, which helps guide the belt and maintain tension.
4. Alternator: From the idler, the belt typically goes up to the alternator pulley.
5. Power Steering Pump: Next, the belt may route down to the power steering pump pulley (if equipped with hydraulic power steering; electric power steering systems will not have this pulley).
6. Water Pump: The belt then commonly wraps around the water pump pulley.
7. Auto-Tensioner: Finally, the belt will route around the automatic tensioner pulley, which provides the necessary constant tension to keep the belt operating correctly.

Remember, this is a general guide. Always refer to your vehicle-specific routing diagram (often found under the hood or in your owner's manual) or your pre-removal photograph for precise routing.

How to Replace the Serpentine Belt

Replacing a serpentine belt on a 2023 Ford Explorer is a moderate DIY task due to engine bay space constraints, but it's certainly achievable with the right tools and patience.

Tools You'll Need:

• Serpentine belt tool or a long 3/8-inch drive breaker bar/ratchet
• Socket (appropriate size for your tensioner pulley bolt/square drive, often 1/2-inch or 3/8-inch square drive)
• New serpentine belt
• Flashlight

Step-by-Step Instructions:

1. Safety First: Ensure the engine is off and cool. Disconnect the negative terminal of your battery for extra safety, though usually not strictly necessary for belt replacement.
2. Document Routing: Crucially, take several clear photos or sketch a diagram of the existing belt routing. This cannot be stressed enough.
3. Locate Tensioner: Identify the automatic belt tensioner. It will have a square hole or a bolt head where your serpentine belt tool or breaker bar will fit.
4. Relieve Tension: Insert your tool into the tensioner's square drive or onto the bolt head. Apply steady pressure in the direction specified by the tensioner (usually clockwise or counter-clockwise, consult your vehicle
