A vehicular cooling system is provided which includes a water tank, a cooling unit, a vent unit, a closed loop conduit assembly, and a water pump. The cooling unit includes an evaporative media in the shape of a closed loop structure having a center hole. The evaporative media is gas porous and preferably made of bactericidal wood shavings. The water pump pumps water from the water tank to saturate the evaporative media to provide water-saturated-air. The cooling unit includes an air pump for sucking air through the evaporative media into a vehicle's interior. Advantageously, the vehicular cooling system requires minimal modification of a vehicle structure.
