Knowing the correct routing and tensioning of the belt not only ensures proper function but also helps prevent costly repairs down the road.
In the following sections, we will explore the importance of the serpentine belt, common signs of belt failure, and how to interpret the specific belt diagram for your 2007 Honda Accord V6. Whether you’re planning a replacement or just want to familiarize yourself with your vehicle’s engine layout, this guide will equip you with the knowledge you need to keep your Accord running smoothly.
Understanding the Serpentine Belt Routing for the V6 Engine
The serpentine belt on the 2007 Honda Accord V6 is a critical component that drives multiple engine accessories using a single, continuous belt. Proper routing of this belt is essential to ensure the alternator, power steering pump, air conditioning compressor, and water pump operate effectively. Misrouting or incorrect installation can lead to premature belt wear or accessory failure.
In the V6 engine configuration, the serpentine belt wraps around several pulleys, each corresponding to a different accessory. A typical routing path for the 2007 Accord V6 includes:
- Crankshaft pulley (primary driver)
- Alternator pulley
- Power steering pump pulley
- Air conditioning compressor pulley
- Water pump pulley
- Idler pulleys (to guide and maintain tension)
- Tensioner pulley (maintains proper belt tension)
The tensioner pulley is spring-loaded to keep the belt tight and compensate for belt stretch over time. When replacing the belt, it is necessary to relieve tension by rotating the tensioner pulley using a wrench or serpentine belt tool.

Steps for Replacing the Serpentine Belt
Replacing the serpentine belt on the 2007 Honda Accord V6 involves several precise steps to ensure proper fitment and tension. Follow these expert guidelines:
- Locate the tensioner pulley: Identify the tensioner pulley and use a suitable wrench or serpentine belt tool to rotate it, releasing tension on the belt.
- Remove the old belt: While holding the tensioner, slide the belt off the pulleys, noting the routing path.
- Inspect pulleys and components: Check all pulleys for damage, wear, or misalignment. Ensure the tensioner operates smoothly.
- Compare new belt to old: Confirm the new belt matches the length and width of the original.
- Install the new belt: Route the new belt according to the correct diagram, leaving the tensioner pulley for last.
- Apply tension: Rotate the tensioner pulley again to allow the belt to slip over it, then release slowly so the tensioner applies tension.
- Double-check alignment: Ensure the belt sits properly in each pulley groove without twisting.
- Test operation: Start the engine and observe the belt running smoothly without noise or slippage.
Common Issues and Troubleshooting
Understanding common serpentine belt problems helps maintain the longevity of your 2007 Honda Accord V6’s accessory drive system. Some frequent issues include:
- Belt squealing or chirping: Often caused by improper tension, worn belt, or misaligned pulleys.
- Cracking or fraying belt edges: Indicates age and deterioration; replacement is necessary.
- Belt slipping off pulleys: Could be due to a faulty tensioner or misrouting.
- Noisy tensioner or idler pulley bearings: May require pulley replacement to prevent belt damage.
- Accessory malfunction: A broken or slipping belt can cause loss of alternator charge, steering assist, or A/C function.
Regular inspection of belt condition and pulley alignment will help prevent these problems before they cause engine accessory failures.
