If you own or operate a Kenworth T680, understanding how to properly drain the air tanks is crucial for maintaining your truck’s braking system and overall performance. While the process is relatively simple, it’s often overlooked, leading to potential issues down the road. This guide will walk you through the steps, explain why it’s important, and provide additional tips to ensure your air system stays in top shape.
Why Drain Air Tanks?
Air tanks on commercial vehicles like the Kenworth T680 are designed to store compressed air, essential for operating the brakes and other pneumatic systems. However, this compressed air naturally contains moisture. Over time, that moisture accumulates within the tanks and can cause several problems:
- Corrosion: Moisture accelerates the corrosion of metal components within the air system.
- Frozen Lines: In colder climates, accumulated water can freeze, blocking air lines and potentially leading to brake failure.
- Reduced Braking Efficiency: Moisture in the brake lines can affect brake response time and overall braking performance. It’s crucial to ensure that your braking system is free from any moisture buildup. Additionally, understanding how to bypass the ignition switch to start a vehicle can be helpful in emergency situations or when dealing with ignition-related issues.
Draining Your Kenworth T680’s Air Tanks: Step-by-Step
Before you begin, park your truck on level ground and ensure the parking brakes are engaged.
- Locate the Drain Valves: The drain valves on the Kenworth T680 are typically located underneath the cab, near the frame rails. They are usually black lanyards or cables that are easily accessible.
- Prepare for Drainage: Position yourself so you can clearly see the area beneath the valves. It’s a good idea to wear safety glasses as some moisture or debris may spray out.
- Pull the Lanyards/Cables: Firmly pull the lanyards or cables associated with each air tank. You may hear a hissing sound as the compressed air is released along with any accumulated water.
- Observe the Drainage: Watch for water exiting the drain valves. The initial discharge may be a mix of air and water, followed by a steady stream of water.
- Continue Draining: Hold each lanyard/cable until the water flow stops and only air is released. This indicates that the tank is drained.
- Repeat for All Tanks: The Kenworth T680 has multiple air tanks, so repeat the process for each one.
- Check for Leaks: After draining, inspect the area around the valves for any signs of leaks. If you notice any, address them promptly to avoid further issues.
Additional Tips for Optimal Air System Maintenance
- Drain Regularly: Make draining your air tanks a part of your routine maintenance schedule. The frequency will depend on your climate and driving conditions. In humid environments or during winter months, more frequent draining may be necessary.
- Use a Water Separator: Consider installing an automatic water separator in your air system. This device helps remove moisture before it reaches the air tanks, reducing the need for manual draining.
- Inspect Air Dryer: Regular inspection and maintenance of the air dryer in your Kenworth T680 truck is paramount to ensuring optimal performance and safety on the road. This component plays a vital role in removing moisture from the air system, preventing corrosion and damage to crucial components. It’s essential to adhere to the manufacturer’s recommendations for replacing the desiccant cartridge, as this ensures the effective operation of the air dryer. By keeping a close eye on the condition of the air dryer and replacing the desiccant cartridge as needed, you can maintain the integrity of the air system in your Kenworth T680 tank, promoting longevity and reliability.

- Check Air Lines: Periodically inspect air lines for signs of wear, damage, or leaks. Replace any compromised lines immediately.
Important Note: If you’re unsure about any aspect of draining your air tanks, consult your Kenworth dealer or a qualified technician.
Conclusion
Draining the air tanks on your Kenworth T680 is a straightforward yet essential task for maintaining the integrity of your truck’s braking system and preventing costly repairs. By following this guide and incorporating regular draining into your maintenance routine, you can ensure optimal performance and longevity for your valuable equipment.
