Important Notes for TC85 Owners
- The 2024 TC85 uses a modern cooling system with lightweight Pankl radiators, built for maximum efficiency and low weight.
- Cooling circuit capacity and bleed location are unique; always bleed trapped air to prevent overheating risk.
- Stick to high-quality coolants compatible with aluminium internals to prevent corrosion and deposit buildup.
Step-by-Step Coolant Change
- Preparation:
- Ensure the motorcycle is on a stable stand and the engine is cold before starting.
- Remove any body plastics or shrouds blocking access to the radiators and cylinder head.
- Drain the Old Coolant:
- Locate the coolant drain bolt at the base of the water pump on the right side of the engine.
- Place your drain pan beneath and remove the drain bolt (use caution as fluid may spill abruptly).
- To accelerate draining, remove the radiator cap on top of the left radiatorthis allows air in and coolant to flow out more quickly.
- Allow coolant to drain from both radiators and the water pump until the system is empty.
- Flush (Optional, for thorough maintenance):
- If you suspect debris or old coolant build-up, re-fit the drain bolt, fill with distilled water, run the engine briefly at idle (with radiator cap removed), shut off, and then drain again.
- Reinstall Drain Bolt:
- Clean the bolt threads and sealing washer, then reinstall and tighten to manufacturer torque spec.
- Refill with Fresh Coolant:
- Pour coolant slowly into the radiator neck until just below the rim with a funnel to avoid spills.
- Key tip for the TC85: Use the dedicated bleeder screw on the cylinder headloosen slightly after filling to let air escape. Watch for a steady stream of coolant with no bubbles, then re-tighten.
- Top off the coolant so it is visible just at the bottom of the radiator cap neck.
- Check for Leaks & Bleed the System:
- Reinstall the radiator cap.
- Start the engine and let it idle for several minutesmonitor for leaks and ensure operating temperature is normal.
- Shut off and allow the engine to cool, then check and top up coolant if necessary.
Why This Matters for Your 2024 TC85
