Keeping your 2018 Yamaha TW200 running cool isn't just about performanceit's peace of mind on any trail or commute. Routine coolant changes help protect your engine and extend the lifespan of key components like the water pump and radiator. Here's a step-by-step, MotoSport-exclusive guide to flushing and changing your coolant, with model-specific notes for TW200 owners.
What Makes the TW200 Different?
The TW200 is cherished for its rugged reliability and distinctive fat tires, ideal for off-roading. Unlike liquid-cooled performance bikes, the TW200 uses an air-cooled engine with an oil cooler, not a traditional liquid coolant and radiator system. This means you do not need to perform regular liquid coolant changes as you would on a liquid-cooled motorcycle.
Instead, it's essential to:
- Regularly check your engine oil level and quality.
- Change your oil and oil filter at the manufacturer's suggested intervals.
- Inspect and clean any external oil cooler or cooling fins to prevent overheating from blocked airflow.
If Your TW200 Has an Aftermarket Liquid Cooling System
Most stock 2018 TW200s are strictly air-cooled, but if you've installed an aftermarket liquid cooling kit, here is the proprietary process for changing the coolant:
- Make sure the engine is completely cool before starting.
- Remove any bodywork obstructing access to the radiator (if applicable).
- Place a drain pan under the coolant drain bolt, typically at the bottom of the radiator or water pump.
- Remove the radiator cap to relieve pressure, then unscrew the drain bolt and allow old coolant to drain completely.
- Reinstall the drain boltdo not overtighten.
- If performing a flush, add distilled water (or a 50/50 vinegar and distilled water mix for stubborn deposits), reinstall the cap, start the engine, and let it reach operating temperature. Allow to cool, then drain again.
- Pour in fresh, motorcycle-specific coolant slowly. Pause when you hear gurglingthis allows air bubbles to escape. Gently squeeze hoses or rock the bike to help "burp" the system.
- Start the engine with the radiator cap off, letting trapped air escape as the engine warms (do not allow overflow). Once bubbling stops and the level steadies, refill as needed and reinstall the cap.
- Check the reservoir tank (if equipped) and fill to the indicated "full" line.
- After a thorough ride, let the bike cool and re-check coolant levelsrefill if necessary.
Critical Maintenance Tips for TW200 Owners
- Since the TW200 primarily relies on air cooling, monitor cooling fins for dirt, mud, or debrisblockages reduce cooling efficiency.
- Never allow the oil level to run low, as oil plays a major role in heat dissipation for this model.
- If you've modified your TW200 with extensive trail gear or crash bars, be mindful not to block airflow across the engine and oil cooler.
- Even without radiator coolant, clean and check the external oil cooler, if installed, to maintain optimal engine temperature.
Staying current on maintenance means your Yamaha TW200 will handle any adventure thrown its way. Whether you're customizing with parts or just need to give your machine some TLC, trust MotoSport to keep you rolling.
