Changing the transfer case fluid in your 2016 Honda Pilot is an essential maintenance task that helps ensure the longevity and performance of your vehicle's all-wheel-drive system. This guide will provide step-by-step instructions, necessary tools, and important tips for a successful fluid change.

Understanding Transfer Case Fluid Change

The transfer case fluid lubricates the gears and components within the transfer case, which is crucial for distributing power to the wheels. Over time, this fluid can degrade, leading to potential issues such as increased wear or even failure of the transfer case. Regular changes are recommended to maintain optimal performance.

Tools and Materials Needed

  • Honda Hypoid Gear Oil (HGO-1): Approximately 0.45 quarts (GL-5 SAE 75W-85)
  • Fluid pump: For transferring fluid into the transfer case
  • 3/8" ratchet and socket: To remove fill and drain plugs
  • Torque wrench: To ensure proper tightening of plugs (set at 33 ft-lbs)
  • 20mm crush washers: Two needed for the drain and fill plugs
  • Drain pan: To catch old fluid
  • Jack and jack stands: For lifting the vehicle safely

Step-by-Step Process

1. Prepare Your Vehicle

- Park on a level surface and engage the parking brake.

- Lift the vehicle using a jack and secure it with jack stands for safety.

2. Locate the Transfer Case Plugs

- The fill plug is located on the side of the transfer case, while the drain plug is at the bottom. Ensure you can access both without obstruction.

3. Remove the Fill Plug First

- Using a ratchet, loosen and remove the fill plug. This step is crucial to relieve any pressure before draining.

4. Drain Old Fluid

- Place a drain pan under the drain plug.

- Remove the drain plug using your ratchet. Allow the old fluid to completely drain out into the pan.

5. Replace Drain Plug

- Once drained, clean the area around the drain hole.

- Install a new crush washer on the drain plug and tighten it securely using your torque wrench set to 33 ft-lbs.

6. Fill with New Fluid

- Use a fluid pump to transfer new Honda Hypoid Gear Oil into the fill hole.

- Fill until fluid begins to overflow from the fill hole, indicating that it’s full.

7. Replace Fill Plug

- Install a new crush washer on the fill plug and tighten it securely with your torque wrench.

8. Clean Up

- Dispose of old fluid properly and clean any spills around the work area.

Important Tips

  • Always use genuine Honda fluids to maintain warranty coverage and optimal performance.

  • Inspect both plugs for wear or damage; replace if necessary.

  • It’s advisable to check transfer case fluid levels regularly, especially before long trips or after heavy use.
