Why Change the Coolant?

The coolant in your KTM 65SX helps regulate engine temperature, preventing overheating and potential damage. Over time, coolant can degrade, losing its effectiveness. Regular changes ensure your engine remains protected.

Tools & Materials Needed

  • New coolant compatible with KTM 65SX
  • Drain pan
  • Socket wrench set
  • Funnel
  • Gloves

Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and the engine is cool. This prevents burns and ensures safety during the process.

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 appropriate level. 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. Check the coolant level again and top off if necessary.
