Tools and Materials Needed

  • Coolant suitable for KTM 65SX
  • Drain pan
  • Socket wrench set
  • Funnel
  • Rags or paper towels
  • Safety gloves

Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable stand and the engine is cool to prevent burns. Wear safety gloves to protect your hands.

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)

If the coolant is particularly dirty, consider flushing the system with distilled water. Reinstall the drain bolt, fill the system with distilled water, run the engine briefly, then drain again.

4. Refill with New Coolant

Reinstall the drain bolt securely. Remove the radiator cap and use a funnel to pour the new coolant into the radiator. Fill until the coolant reaches the top of the radiator neck.

5. Bleed the System

Start the engine and let it idle for a few minutes. This helps remove air pockets from the system. Check the coolant level and top off if necessary.

6. Check for Leaks

Inspect the drain bolt and radiator cap for any leaks. Tighten if needed. Clean any spilled coolant with rags or paper towels.
