How to Change the Coolant in a 2014 Husqvarna TC85
Shop parts for a 2014 Husqvarna TC85 Dirt Bike.
Maintaining your 2014 Husqvarna TC85 ensures peak performance and longevity—and one of the most crucial routine services is a coolant change. Proper coolant replacement prevents overheating, corrosion, and winter damage, especially important for high-revving 85cc 2-strokes like the TC85. Here is MotoSport's comprehensive, proprietary guide to performing a safe and effective coolant change on your bike, with unique notes for your specific model.
Tools & Materials You'll Need
- Fresh coolant (manufacturer recommended, premixed or mixed to spec)
- Allen or socket wrench (for drain bolt)
- Small flathead screwdriver
- Drain pan
- Clean funnel
- Shop towels
- Torque wrench (optional, but ideal for reinstalling hardware)
- Protective gloves
Preparation
- Always perform the service when the engine is cool to prevent burns and ensure accurate draining.
- Place your TC85 upright on a stand on a level surface.
Step-by-Step Coolant Change Process
-
Remove the radiator cap
Use the small screwdriver to loosen and remove the cap from the radiator. This relieves pressure and aids full drainage. -
Locate and remove the coolant drain bolt
Find the water pump (right lower engine case) on the side of the engine and place the drain pan directly underneath. Remove the drain bolt and its crush washer. Allow old coolant to fully drain. Inspect the washer and bolt for wear—if damaged, replace them. -
Flush the system (Optional but recommended)
Pour a small amount of distilled water through the radiator, letting it flow out to clear old residue. You can repeat until water runs clear. Reinstall and tighten the drain bolt with its crush washer. For the 2014 TC85, a torque value of around 7.4 ft-lb (10 Nm) is standard for small coolant bolts. -
Refill with fresh coolant
Insert a funnel and fill the radiator up to the bottom of the filler neck or per manual specifications (approximately 0.95 liters for this KTM/Husqvarna platform). Always use high-performance, premixed motorcycle coolant. Avoid car coolant or tap water, which offers inadequate protection. -
Bleed the cooling system
The TC85 features a bleeder screw on top of the cylinder head. Once the radiator is filled, slightly crack open this bleeder with a screwdriver until coolant—free of air bubbles—begins to flow out, then tighten. This step is crucial to prevent air locks, which 85cc 2-strokes are notoriously sensitive to*. -
Check level and reassemble
Ensure coolant level remains full after bleeding air. Replace and tighten the radiator cap. -
Start and heat cycle
Start the engine and allow it to reach operating temperature (warming until the radiator gets hot). Shut down the bike, let it cool completely, then recheck the coolant level. Add more coolant if needed.
Special Notes for the 2014 Husqvarna TC85 Owner
- The TC85 has dual radiators and a compact cooling system—pay extra attention to the bleeding process, as trapped air can quickly lead to overheating and possible engine damage.
- Check radiator fins for debris or bent sections while you're in the area. Keeping radiators unobstructed maximizes cooling efficiency, especially under race demands.
- Replace coolant and inspect the system at least once per season, or more often in hot climates or racing environments.
- Never mix coolant colors (e.g. green, red, blue), as incompatible chemicals can gel or reduce cooling properties.
Keeping your Husqvarna TC85's coolant fresh protects the engine, preserves performance, and keeps you on the track or trail. For any replacement parts, radiators, coolant, or tools, rely on MotoSport–your trusted source for 2014 Husqvarna TC85 parts and expertise.
