Hi Everyone,

Time to change my coolant on the grizzly 450, service manual just says to basically remove coolant drain plug from cylinder and drain plug from water pump, and drain reservoir and thats it…

Question: Is there anything else i should do, like sucking the old coolant out or something to make sure i get ALL the old coolant out?

Also, when re-filling the system, is there anything i should to to bleed out all of the air in the system? Service manual says nothing, just says "Fill cooling system"
