A filtering apparatus for filtering contaminants from a cooling system for an internal combustion engine (14) with a liquid cooled radiator (11) comprising a filtering screen (7) to remove unwanted contaminants from the radiator fluid without substantially restricting fluid flow. Placed in a direct flowpath of the fluid, the filtering screen (7) comprises a filtering surface and a semi-detachable precut flap (22). The precut flap (22) can be partially cut to open once a specific flow pressure is reached thereby, as filtered contaminants become deposited on the filtering surface and increase in the flow pressure, the precut flap (22) will open in the direction of the flow so as to provide sufficient fluid for the successful operation of the cooling system. |
