Tools and Materials Needed

Step-by-Step Guide

1. Prepare Your Bike

Ensure your KTM 525SX is on a stable surface and completely cool to prevent burns. Wearing safety gloves is recommended.

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

To remove any residual coolant and debris, flush the system with distilled water. Reinstall the drain bolt temporarily, fill the radiator with distilled water, and run the engine for a few minutes. Turn off the engine and drain the water.

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 and radiator cap.

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 again and top off if necessary.

6. Final Check

Inspect the area for any leaks and ensure the radiator cap is secure. Dispose of the old coolant responsibly, as it is toxic and harmful to the environment.
