Changing the coolant in your 2022 Husqvarna TC85 is a vital maintenance task that keeps your engine running cool under demanding conditions. Here is a detailed, MotoSport-exclusive step-by-step guide that addresses the unique features and service tips for the TC85.
What Makes the 2022 TC85 Special?
- High-performance 2-stroke cooling system: The TC85 is equipped with twin radiators and a cylinder-head bleeder port to ensure optimal cooling and minimize risk of air pockets in the system.
- Lightweight frame: Accessibility is relatively straightforward, but precision matters to prevent leaks or incomplete air removal.
- Coolant capacity: Approx. 0.95 L (about 1 US quart) is standard for the TC85's system.
Tools & Supplies Needed
- 10 mm or 8 mm socket/ratchet (for drain bolt)
- Torque wrench
- Funnel
- Catch pan
- Soft shop towel
- New copper crush washer (recommended)
- Fresh, high-performance coolant formulated for motocross applications
Step-by-Step Coolant Change Instructions
-
Prepare the Bike
Ensure the TC85 is on a stable stand, engine completely cool, and work area is ventilated. -
Remove the Radiator Cap
Slowly open the radiator cap located at the top of the right-side radiator to release pressure and allow coolant to drain more efficiently.
Tip: Press down and rotate counterclockwise. -
Locate & Remove the Drain Bolt
The coolant drain bolt is on the lower water pump cover (right side of the engine). Place your catch pan directly below. Loosen and remove the bolt to let the old coolant drain.
Replace the copper crush washer if you have a new one; otherwise, clean and flip the old washer as a temporary solution. -
Drain Both Radiators
Allow several minutes for all coolant to leave the system. Gently tilt the bike left and right to ensure both radiators empty.
Wipe up any spills with a shop towel, being careful not to introduce debris into the open system. -
Reinstall & Torque the Drain Bolt
Insert the drain bolt with the washer and torque to 10 Nm (7.4 ft-lb) to prevent leaks. -
Refill With Coolant
Using a funnel, add fresh coolant through the radiator fill neck. Fill until the fluid level reaches just above the radiator fins. -
Bleed Air from the System
The TC85 features a bleeder screw on the cylinder head. With the radiator cap still off, crack the bleeder screw open until air stops bubbling out and a steady stream of coolant emerges. Re-tighten the screw. -
Top Off and Replace Cap
Add coolant if the level has dropped. Reinstall the radiator cap securely. -
Check for Leaks and Test
Start the bike briefly and let it idle, then shut off and let cool. Re-check coolant level and add if necessary.
TC85 Maintenance & Coolant Tips
- Always use a coolant designed for high-performance motocross motorcycles to prevent engine corrosion and overheating.
- Inspect radiator hoses for cracks or swelling during service.
- Check for leaks at the drain bolt and radiator cap after filling.
- Dispose of old coolant responsibly–it is toxic and should never be poured down drains or onto the ground.
Your 2022 Husqvarna TC85's cooling system is engineered for high RPM, big air, and extreme competition. Make coolant changes a regular part of your maintenance schedule to keep your machine running strong all season.
