Hi everyone. I am in the process of replacing the head and upper gaskets on this 06 RTV900 and cant find out how to drain ALL of the coolant from the block. I have drained and removed the radiator to have it cleaned and checked but there is still allot of coolant in the jackets I want to get out. The maint manual doesn't seem to address this only says to remove the plug in the bottom of the radiator. Thanks again for all of the help!!
