Tools and Materials Needed

  • Coolant suitable for the KTM 85SX
  • Socket wrench set
  • Drain pan
  • Funnel
  • Rags or paper towels
  • Safety gloves

Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and the engine is cool to the touch. This prevents burns and ensures the coolant system is depressurized.

2. Drain the Old Coolant

Locate the coolant drain bolt on the water pump cover. Place a drain pan underneath and use a socket wrench to remove the bolt. Allow the old coolant to fully drain into the pan.

3. Flush the System (Optional)

For a thorough clean, flush the system with distilled water. Reinstall the drain bolt, fill the system with water, run the engine briefly, then drain again.

4. Refill with New Coolant

Reinstall the drain bolt securely. Using a funnel, pour the new coolant into the radiator until it reaches the top. Check for any leaks around the drain bolt.

5. Bleed the System

Start the engine and let it idle. This allows air bubbles to escape. Keep an eye on the coolant level and top off as necessary.

6. Final Checks

Once the engine is cool, recheck the coolant level and add more if needed. Ensure all bolts are tight and there are no leaks.
