Tools and Materials Needed

  • Coolant compatible with KTM 50SX
  • 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 surface and the engine is cool to the touch. This prevents burns and ensures the coolant system is depressurized.

2. Remove the Radiator Cap

Locate the radiator cap on the top of the radiator. Twist it counterclockwise to remove it. This will allow the coolant to drain more easily.

3. Drain the Old Coolant

Place a drain pan under the engine. Locate the coolant drain bolt on the water pump cover. Use a socket wrench to remove the bolt and allow the old coolant to fully drain into the pan.

4. 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 water, run the engine briefly, then drain again.

5. Refill with New Coolant

Reinstall the drain bolt securely. Using a funnel, pour the new coolant into the radiator until it reaches the top. Ensure you use a coolant that is compatible with the KTM 50SX.

6. Bleed the System

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

7. Reinstall the Radiator Cap

Once the coolant level is stable, reinstall the radiator cap securely.
