Items You'll Need

- Funnel for filling
- Socket set – for radiator cap and drain bolt
- Protective gloves and eyewear
- Torque wrench (for proper torque spec on drain screw)
- Clean shop rags
Step-by-Step Coolant Change Procedure
-
Ensure Bike is Cool & Stable.
Park the bike on a level surface and allow the engine to fully cool. This helps prevent burns and ensures accurate coolant measurement. -
Drain the Old Coolant.
Locate the water pump cover (on the right lower side of the engine). Place your drain pan underneath. Remove the drain screw on the cover. Open the radiator cap at the left side of the bike to allow air in and promote full drainage.
Let all the old coolant drain completely.
Dispose of old coolant safely—it is toxic. -
Inspect the System.
Before refilling, inspect the radiator, hoses, and water pump area for any leaks or debris. Replace parts as needed to avoid future cooling system issues. -
Refit and Torque the Drain Screw.
Clean the drain screw threads and reinstall it once the fluid stops draining. Torque to manufacturer specification to avoid leaks (consult your owner's manual for the recommended value). -
Refill with New Coolant.
Slowly pour new coolant into the radiator up to the marked level using a funnel. Filling slowly helps prevent air pockets. For best results, fill the upper radiator first, then crack the small bleeder screw on top of the cylinder head briefly to purge trapped air. Retighten the bleeder screw after air is released. -
Bleed Air from the Cooling System.
Air pockets can cause overheating. After refilling and bleeding via the screw, gently rock the bike from side to side to encourage more trapped air to move upward. Re-check the coolant level and top off if needed. -
Replace Radiator Cap and Clean Spills.
Secure the radiator cap. Wipe down any spilt coolant. Run the engine for several minutes, then shut it off and let cool. Re-check the coolant level once more, topping up as needed.
Tips & Warnings for Your TC85BW
- Only use coolant compatible with aluminum radiators and high-revving two-stroke engines.
- If you race in extreme climates (hot or cold), use a coolant blend designed for those conditions.
- If coolant comes into contact with your skin or eyes, flush immediately with water and seek prompt medical attention if needed. Swap out any clothing exposed to coolant immediately for safety.
- Never remove the radiator cap when the engine is hot. Serious burns could result from pressurized steam or hot fluid.
When to Change Your Coolant
For best performance and long engine life, change the coolant every two seasons at minimum, or after any major engine work or overheating incident.
