In the beginning, it will spin slowly. When the water in radiator get hot, air passing thru the radiator will heat up the bimetallic strip of the fan clutch. This will in turn make the bimetallic strip to bend outward and allow more silicon oil to flow and hence make the fan to spin faster. When the fan spin faster it will cool the radiator faster and will keep the radiator operating at optimum temperature. Vice-versa, when the temperature in the radiator dropped, the bimetallic will contract and reduce the speed of the fan.</p></blockquote><p></p>
