Keeping your 2016 Yamaha TW200 running smoothly means periodic cooling system maintenance. Changing the coolant not only prevents overheating but also protects the engine and water pump from corrosion and premature wear. Here–s a step-by-step, proprietary MotoSport guide for confidently changing your TW200–s coolant and keeping your adventure going strong.
What You Need
- Fresh coolant (check your manual for correct type–most modern 4-stroke motorcycles use ethylene glycol-based pre-mix for aluminum engines)
- Distilled water (for flushing if needed)
- Socket set and screwdriver
- Drain pan
- Funnel
- Replacement sealing washer (for drain bolt, if needed)
- Gloves and rags
Model-Specific Note: 2016 Yamaha TW200
Your TW200 is known for robust reliability and a relatively simple air-cooled (not liquid-cooled, with radiator) engine design. Be aware that unlike many modern dirt bikes, the TW200 does not use a pressurized, radiated liquid cooling system—it relies on air cooling via cooling fins and engine oil for heat management.
The TW200 does not have a coolant system or reservoir to service. Routine maintenance of this bike involves regular oil changes and checking the condition of cooling fins for dirt, mud, and debris–not coolant changes.
If you–ve installed aftermarket or custom radiators for extreme conditions or high-performance builds, follow the radiator coolant procedure below, but for a stock 2016 TW200, coolant flushes are unnecessary because the system is air-cooled.
If You Have an Aftermarket Radiator or a Liquid-Cooled Conversion
For modified TW200s running a liquid-cooling system, follow these steps:
- Let the engine cool completely. Never attempt to drain coolant from a hot bike–danger of burns.
- Remove side panels or bodywork for access. Locate the coolant drain bolt–often positioned at the lowest point of the water pump or radiator.
- Place a drain pan under the drain plug. Remove plug and let old coolant drain completely.
- If flushing, reinstall the drain bolt and pour distilled water through the system. Let it drain out. Repeat until water runs clear.
- Install a new sealing washer on the drain bolt if required. Tighten the bolt securely.
- Add fresh coolant through the radiator cap. Pour slowly with a funnel, checking the fill level.
- Burp the system. With the radiator cap off, start the engine and let it run. Gently rev and rock the bike to remove air bubbles.
- Top off coolant as needed. Once bubbling stops, refill to the base of the filler neck. Install the radiator cap.
- Check for leaks. Let the bike heat-cycle, cool off, and recheck coolant levels after first ride.
Care Tips for Stock TW200 Cooling
- Routinely inspect and clean the engine–s cooling fins. Mud, debris, or caked-on grime insulate the engine and can cause overheating.
- Change engine oil at recommended intervals–on the TW200, oil helps dissipate engine heat.
- Monitor for oil leaks or excessive engine heat, especially after extended low-speed riding or heavy loads.
- If you frequently ride in slow, technical terrain, consider oil coolers or other upgrades for enhanced thermal stability.
Your 2016 Yamaha TW200 is engineered for reliability and simplicity, making maintenance straightforward. With no coolant system to flush on the stock model, you–ll save time and get back to your ride faster.
