Condensers & Radiators must be allowed to work properly to remove heat from the unit they are protecting. Heat will always transfer to a cooler surface and that is how simple Engine, Hydraulic or Fuel Cooling and even Air Conditioning Systems Work. The Heat transfers to the fluid because it is cooler..then is returned to the Condenser or Radiator and the heat transfers to it then the air blows the heat away and the cycle continues. BUT if the system becomes restricted to reduce the amount of heat that can be removed...eventually the system will over heat and can damage components.
Keep more money in your pocket by investing a few minutes a day to keep your cooling systems clean. An AGCO Parts Air Comb can help save you Thou$and$ in unnecessary maintenance costs.
