Engine Cooling System Components

NOTE: Radiator drain on 5420 and 5520 tractors is located in the lower left corner of the radiator.

IMPORTANT: Never pour cold water into the cooling system of a hot engine, as it might crack cylinder block or head. DO NOT operate engine without coolant for even a few minutes.

The tractors utilize a remote coolant recovery tank. Make-up coolant is added to the coolant recovery tank rather than directly to the radiator.
