How much putoline nf radiator coolant do I put in my 2003 sherco 250? Also how do I drain the old stuff out?

Some water pumps have a drain screw.  Otherwise, you’ll have to temporarily remove a hose.  You may need to tip the bike to get out as much old coolant as possible.

Refill so the tops of the radiator tubes are just covered.  Run the bike for 30 seconds to see if any air was trapped in the system.  Refill if necessary.  Since there is no coolant recovery tank, any excess (due to thermal expansion) will just flow out the overflow hose.  This is the correct level.
