What You Will Need
- 10mm socket and ratchet
- 8mm socket (for side panel removal)
- Screwdriver
- Funnel

Before You Start
- Ensure the engine is completely cool before opening the cooling system to avoid burns.

Step-by-Step Coolant Change for the KLX230R
- Remove Side Panel: Use the 8mm socket to take off the left side panel for access to the overflow reservoir.
- Remove Radiator Cap: Carefully unscrew the radiator cap. Place a rag over the cap and release pressure slowly.
- Drain Old Coolant: Place the drain pan under the coolant drain bolt (usually on the lower side of the water pump cover). Remove the bolt using a 10mm socket and allow the coolant to fully drain. Also, drain the overflow reservoir using the accessible drain plug or by removing the tank if necessary.
- Flush (Optional but Recommended): Install the drain bolt and fill the system with distilled water. Run the engine briefly to circulate, then repeat the drain process. This removes any residue or debris.
- Reinstall Drain Bolt: Fit a new washer if available, tighten the drain bolt securely, and check for leaks.
- Refill with New Coolant: Using a funnel, slowly pour the recommended motorcycle coolant into the radiator until full. Fill the overflow reservoir up to the correct level as indicated on the tank.
- Remove Air Bubbles: Start the engine with the radiator cap off. Allow the bike to idle, gently rev a few times, and observe as trapped air escapes. Top off coolant as needed (never let the radiator run dry).
- Replace Radiator Cap & Side Panel: Secure the radiator cap and reinstall the side panel. Fully wipe away any spilled coolant.
- Test Ride: After warm-up, double check the coolant level. Add more coolant if level drops, indicating remaining air has purged.
