Performing a fluid change on your Honda Pilot’s AWD system is essential for maintaining optimal performance and longevity. However, after replacing the fluid, it’s crucial to properly bleed the system to remove air pockets that can cause uneven operation or damage. This guide will walk you through the steps to properly bleed your Honda Pilot AWD system after a fluid change.
Tools and Materials Needed
- New transfer case fluid
- Drain pan
- Socket set and wrenches
- Funnel
- Clean rags
- Gloves and safety glasses
- Jack and jack stands
Preparation Steps
Begin by parking your Honda Pilot on a level surface and engaging the parking brake. Lift the vehicle using a jack and secure it with jack stands for safety. Wear gloves and safety glasses to protect yourself during the process. Locate the transfer case drain and fill plugs, typically found on the underside of the vehicle.
Draining and Filling the Transfer Case
Remove the drain plug and allow the old fluid to fully drain into your pan. Once drained, replace the drain plug securely. Using a funnel, fill the transfer case with the recommended Honda-approved fluid until it reaches the fill port. Replace the fill plug tightly.
Bleeding the System
To remove trapped air, start the vehicle and turn on the AWD system. Shift the transmission through all gears, including park, reverse, and drive, while the vehicle is running. This helps circulate the new fluid and expel air pockets. Keep the engine running during this process.
Next, with the engine still running, lift and support the vehicle. Loosen the fill plug slightly to allow any trapped air to escape. You may notice bubbles or air pockets emerging. Once no more air escapes and the fluid is steady, tighten the fill plug securely.
Final Checks and Test Drive
Lower the vehicle from the jack stands and double-check all plugs for tightness. Start the engine again and verify that the AWD system is functioning smoothly. Take the vehicle for a short test drive, paying attention to any unusual noises or vibrations. Recheck fluid levels and top off if necessary.
By following these steps, you ensure your Honda Pilot’s AWD system is properly bled and ready for reliable performance. Regular maintenance and proper bleeding can extend the life of your drivetrain components and improve safety on the road.
