Keeping the coolant fresh in your 2014 Husqvarna TC85BW is crucial for engine performance, especially since this 2-stroke race bike is designed to be pushed hard in demanding off-road conditions. The TC85BW features a robust cooling system, but dirt, mud, and extreme heat can break down coolant and reduce protection over time. Regular coolant changes prevent overheating, corrosion, and costly engine damage, so here’s a proprietary step-by-step guide from the MotoSport team.
What You Need
- Fresh motorcycle-specific coolant
- Drain pan
- Clean funnel
- 8mm or 10mm wrench (depending on your model)
- Shop rags
- Optional: distilled water for flushing
- Safety gloves – coolant is toxic
Coolant Change Procedure
- Prep the Bike
Make sure the engine is fully cool to avoid burns. Place the bike upright on a stand so it sits level for thorough draining. - Access the Radiator Cap
Remove the seat and left side panel as needed. Unscrew the radiator cap slowly to release any pressure in the system. - Drain the Coolant
Position a drain pan under the right side of the engine near the water pump. Locate the coolant drain bolt – typically on the lower water pump cover. Use the correct socket to loosen and remove the bolt.
Allow all coolant to completely drain out. Tip the bike gently side to side (on level ground) to help flush out remaining fluid. If desired, you can flush the system further by pouring a small amount of distilled water through the radiator neck, then drain again. - Reinstall the Drain Bolt
Clean the bolt and sealing surface. Reinstall and tighten the drain bolt securely, being careful not to overtighten and strip the threads. - Fill with Fresh Coolant
With the drain sealed, insert a clean funnel into the radiator neck. Slowly pour in the recommended amount of fresh coolant, pausing occasionally to let air escape. Fill to the base of the filler neck. Check your manual for exact capacity—most 85cc two-strokes require less than one quart. - Bleed Air from the System
The TC85BW cooling system can trap air, especially after a full drain. Some models include a small bleeder screw on top of the cylinder head. Crack the bleeder while refilling until coolant flows out without bubbles, then retighten.
If your bike has no bleeder, gently rock the bike side-to-side or squeeze the radiator hoses to help push trapped air out. - Initial Run – Final Checks
With the radiator cap off, start the bike and let it idle briefly. Watch for coolant level to drop slightly as trapped air purges. Top up the radiator as needed, then fit the cap securely.
Inspect all bolts and hose connections for leaks. - Allow the Engine to Cool
After the first run, let the bike cool completely, then recheck the coolant level. Top off if necessary.
Model-Specific Notes for the 2014 TC85BW
- Wide Wheel (BW) Design: This TC85BW features a larger wheelset, which increases ground clearance. Double check that your bike is level for accurate draining & filling.
- Frequent Racing & Harsh Conditions: Riders in muddy or sandy environments should change coolant more frequently due to the extra strain and debris exposure.
- Premix Ratio: Always maintain the correct 2-stroke premix ratio as overheating caused by lean mixtures cannot be solved by coolant alone.
- Check Seals & Hoses: At every coolant change, inspect for swelling, cracks, or leaks around hoses, clamps, and the water pump. Replacement parts are available through MotoSport for hassle-free ordering.
When to Change the Coolant?
- At least once per season for riders who race
- More often if riding in mud or extreme heat
- When changing to a new coolant type (always completely flush the old coolant)
- If you see rust, debris, or oil in the drained coolant
Using the right coolant and proper service intervals keeps your 2014 Husqvarna TC85BW running cool in any condition. If you notice repeated coolant loss, overheating, or milky residue under the radiator cap, troubleshoot for possible leaky gaskets or a faulty water pump seal.
MotoSport makes it easy to find everything you need, from gaskets to high-performance coolants. Ride with confidence on your TC85BW – a little maintenance goes a long way to protect your investment.
