2022 Toyota Camry Serpentine Belt Routing & Part Numbers

As an ASE-certified master technician, I regularly see the 2022 Toyota Camry roll into the bay for routine maintenance. While modern Camrys are incredibly reliable, their serpentine belts and tensioners bear a massive workload and eventually require replacement. Whether you are dealing with the standard 2.5L 4-cylinder or the potent 3.5L V6, installing a new drive belt is a straightforward job if you have the right parts, tools, and routing knowledge.

Here is your comprehensive reference guide for servicing the serpentine belt on a 2022 Toyota Camry.

Quick Answer

Before diving under the hood, make sure you have the correct replacement parts. Note that exact part numbers can vary slightly depending on your specific engine option (2.5L vs. 3.5L V6), but the specifications below represent the traditional full-accessory layout:

• Rib Count: 6-rib
• Belt Length: 82.5 inches (approximate for standard full-routing setups)
• OEM Belt Part Number: 90916-02652
• Aftermarket Cross-References: Gates K060825, Dayco 5060825, Continental Elite 4060825
• Auto-Tensioner Part Number: OEM 16620-31012 (Gates 38240)
• Idler Pulley Part Number: OEM 16604-31020

Belt Routing

Pro-Tip: Always use your smartphone to take a clear photograph of the existing belt routing before you relieve the tension and remove the old belt. It is the best insurance against getting stuck during reassembly.

Since we cannot render an image here, follow this text-based step-by-step description of the routing path. Starting from the bottom of the engine and working your way around:

1. Crankshaft Pulley: The belt starts by looping down and around the large ribbed crankshaft pulley at the bottom center of the engine.
2. A/C Compressor: From the bottom of the crank, the ribbed side of the belt routes over to the Air Conditioning (A/C) compressor pulley.
3. Idler Pulley: The belt then heads upward, with the smooth backside passing under/around the smooth idler pulley.
4. Alternator: The ribbed side loops up and tightly over the alternator pulley at the top of the engine block.
5. Power Steering (if equipped/applicable to layout): The belt comes down from the alternator and wraps around the power steering pump pulley.
6. Water Pump: The smooth backside of the belt then routes across the smooth water pump pulley.
7. Tensioner: Finally, the belt goes down around the auto-tensioner pulley before returning to the crankshaft.

How to Replace the Serpentine Belt

Replacing the drive belt on your Camry can usually be completed in under 30 minutes with basic hand tools.

Tools Required:

• A dedicated serpentine belt tool or a long-handled 3/8" drive breaker bar.
• Safety glasses and gloves.

Step-by-Step Replacement:

1. Locate the Auto-Tensioner: Find the spring-loaded automatic belt tensioner on the front of the engine block.
2. Release Tension: Insert your 3/8" breaker bar or serpentine belt tool into the square receptacle on the tensioner arm (or use the designated hex bolt, depending on your exact engine configuration). Rotate the tensioner counter-clockwise (away from the belt) to relieve the spring pressure.
3. Remove the Belt: Slide the old belt off the easiest-to-reach smooth pulley (usually the idler or water pump) while holding the tensioner open. Carefully release the tensioner back to its resting position.
4. Route the New Belt: Feed the new belt down through the engine bay, following the exact routing path outlined above. Leave that same smooth pulley for last.
5. Install: Rotate the tensioner open once more, slip the belt over the final pulley, and slowly release the tensioner.
6. Verify: Double-check that all belt ribs are perfectly seated inside the grooves of the ribbed pulleys before starting the engine.

Replacement Interval

For the 2022 Toyota Camry, the serpentine belt should be visually inspected every 15,000 miles. A complete replacement is typically recommended between 60,000 and 90,000 miles, or every 5 to 7 years, whichever comes first. The EPDM rubber used in modern belts wears down like a tire tread rather than cracking, so mileage is a critical metric.

Signs of a Failing Belt or Tensioner

Do not wait for a complete belt snap to address wear and tear. Watch for these common warning signs:

• Squealing or Chirping Noises: A high-pitched squeal on startup or during heavy acceleration usually indicates a stretched belt or a weak tensioner spring.
• Accessory Malfunctions: A slipping belt can lead to poor A/C performance, a flickering battery/charging light on the dashboard, or heavy steering.
• Physical Wear: Look for missing ribs, frayed edges, or deep cracks on the ribbed side of the belt.
• Tensioner Rattle: If the auto-tensioner is bouncing excessively while the engine runs or makes a grinding noise, the internal bearings or spring have failed and the tensioner assembly must be replaced alongside the belt.

Replacing the serpentine belt is a great DIY task, but if you don't have the tools, time, or confidence to tackle the job yourself, don't risk a breakdown. Find a trusted shop on Repairius.
