What is the best way to drain the radiator fluid on my WR250F? I know there is a cap on the top of the radiator, but is there a screw on the bottom that can be removed to drain the fluid or do you have to take the radiator off and pour it out?


regards,


christopher

There should be a drain bolt under the water pump on the side of the engine. Be sure to use distilled water and coolant for aluminum engines when you refill it. The coolant will provide some corrosion resistance for waterpump and coolant passages. Tap water has alot of contaminents that can harm the cooling system.

Umm, no. You have to dilute most coolants. You generally mix at 50/50 with distilled water to provide freeze and corrosion protection.
