Shop parts for a 2017 Yamaha TW200 Dirt Bike.
Maintaining optimal cooling performance is essential for the longevity and reliability of your 2017 Yamaha TW200. The process of changing the coolant not only helps prevent overheating but also protects engine components from corrosion and buildup. The following step-by-step guide is tailored for the TW200 owner and ensures you keep your bike performing at its best.
Tools & Supplies Needed
- Phillips and flathead screwdrivers
- Socket wrench set
- Drain pan or container
- Moto-specific or universal engine coolant (non-silicate, pre-mix recommended)
- Funnel
- Clean shop rags
- Torque wrench (for precision, if available)
- Distilled water (if your coolant is concentrate)
Step-by-Step Coolant Change on the TW200
- Preparation
- Ensure the engine is completely cool before starting to avoid burns or accidental steam release.
- Place the TW200 on a stable stand for easy access and safety.
- Remove Body Panels (if necessary)
- On the TW200, minimal bodywork hinders coolant access. Some models may require side panel removal for easier access to the radiator cap and overflow reservoir. Use a Phillips screwdriver to remove necessary fasteners and panels, keeping all hardware safely aside.
- Drain Old Coolant
- Locate the radiator drain bolt (usually at the lowest point of the radiator or water pump). Position your drain pan directly beneath.
- Loosen the drain bolt and allow all coolant to flow out. Also, loosen the radiator cap to facilitate flow and maximize drainage. Some TW200s include a small bleeder screw at the pump–if so, remove it to ensure all coolant is drained.
- Flush System (if desired)
- If you're flushing, re-install the drain bolt temporarily and fill the system with distilled water. Run the engine briefly, then drain again. Repeat until the drained water is clear.
- Inspect Components
- Check hoses, clamps, and radiator for cracks, swelling, or leaks during the draining process. Replace any suspect parts using genuine TW200 components for best results.
- Refit Drain Bolt & Bleed Screw
- Reinstall the drain bolt with its washer and tighten firmly (do not overtighten). Reinstall the bleeder screw if equipped.
- Add New Coolant
- Using a funnel, pour new coolant into the radiator up to the base of the neck. For best performance, use a coolant specified for motorcycles and avoid automotive coolant due to additive incompatibility. If using concentrate, mix 50/50 with distilled water.
- Fill the overflow reservoir to the recommended level.
- Bleed Air from System
- With the radiator cap still off, start the engine and let it idle. Gently rev the engine and rock the bike to help release trapped air (called <
> the system). If a bleeder screw is present, briefly loosen it until only coolant (no bubbles) escapes, then tighten again.
- With the radiator cap still off, start the engine and let it idle. Gently rev the engine and rock the bike to help release trapped air (called <
- Check & Top Off
- Turn off the engine and wait for it to cool. Top off the radiator and reservoir, if necessary.
- Replace and secure all removed body panels and fasteners.
- Test and Inspect
- Start the TW200 and allow it to reach operating temperature. Monitor for leaks around hoses and the radiator. Check the coolant level again after the engine has cooled, topping off as needed.
- Dispose of Old Coolant
- Bring used coolant to a local auto parts store or hazardous waste center for safe disposal as it is toxic to people and pets.
TW200 Model-Specific Tips & Notes
- The Yamaha TW200's air-cooled engine is unique among trail bikes, but the model starting in recent years uses a small auxiliary oil cooler. If your 2017 model is the standard air-cooled version, coolant maintenance is not needed – you may only need to maintain the oil level. If, however, yours has had aftermarket water-cooling or an auxiliary system installed, the above steps apply.
- Yamaha's stock TW200 for 2017 requires only standard oil and filter changes under normal maintenance. If your bike does not have a radiator or coolant reservoir, double-check if the cooling system is an aftermarket addition.
- Always check your owner's manual for service intervals and any TW200-specific torque specs for drain bolts and fasteners.
Keeping your 2017 Yamaha TW200 in optimal condition is easy with regular maintenance—and with parts from MotoSport, it's easier than ever to stay on the trail.
