Changing the coolant in your 2007 Yamaha TW200 is crucial for engine longevity and peak performance. This dual-sport bike uses a relatively simple air-cooled engine, but some late-model TW200s and similar bikes use an oil cooler or can benefit from coolant system service if aftermarket modifications have been made. Follow this MotoSport-exclusive guide for a proper coolant change.
What Makes the 2007 Yamaha TW200 Unique?
The 2007 TW200 relies primarily on air-cooling and does not feature a standard liquid cooling system found on many modern dirt bikes. However, some owners add oil coolers or maintain a cooling loop for aftermarket parts. This guide covers the procedures you might need if your model has a coolant system or if you have added an oil coolerbe sure to check your specific setup before starting.
What You Need
- Fresh coolant (or oil, if servicing an oil cooler)
- Distilled water (if flushing)
- Basic hand tools (screwdrivers, socket set)
- Drain pan
- Funnel
- Shop rags
- Protective gloves & eye protection
Step-by-Step Coolant Change for the TW200
- Let the Engine Cool – Never open the system when hot. Wait until the engine is completely cool for safety and the best results.
- Locate the Drain Bolts – For most standard TW200s, this step is unnecessary. If equipped with an aftermarket cooling system, locate the drain bolt at the water pump or lowest cooling hose.
- Place Drain Pan – Position your drain pan underneath the drain point to catch all old coolant or oil.
- Remove Drain Bolt – Use your socket set to loosen and remove the drain bolt. Allow all fluid to fully drain.
- Flush the System (Optional) – Pour distilled water into the fill cap, reattach the bolt, and run the engine for a few minutes if a deep flush is desired. Shut off, cool, and drain again.
- Replace the Drain Bolt – Install a new sealing washer if necessary & tighten the bolt to spec.
- Refill With Coolant – Using your funnel, pour fresh coolant to the upper line on the overflow reservoir or to the neck of the fill port, depending on your installation. Use only coolant recommended for motorcyclesnever use tap water.
- Remove Air – If your system has a radiator, start the bike with the cap off and gently rock the bike while blipping the throttle to help bubbles escape. Fill as needed, burping the system until fluid level is stable and free of bubbles.
- Check Levels & Inspect – With the system cool, check the fill and reservoir one last time. Top off if necessary. Inspect for leaks and ensure all bolts are properly tightened.
Special Notes for TW200 Owners
- The TW200 stock engine is air-cooled—if you do not have any aftermarket liquid cooling parts, you do not need to perform this service. Maintain the oil and air-cooled fins instead.
- Always use the correct fluids—non-motorcycle-specific antifreeze or coolant can damage the system or harm seals.
- Dispose of used coolant responsibly at a recycling center.
- If your TW200 is highly modified with cooling system changes, consult your part manuals or trusted mechanic for best practices unique to your setup.
