Claim:
A cooling system of an amphibious vehicle having a prime mover cooled by liquid coolant that circulates through a radiator and at least one retractable wheel assembly, the cooling system comprising: at least one duct running from a first proximal end of the vehicle to a second distal end of the vehicle wherein the radiator is not located within the duct, the at least one duct having: at the first proximal end at least one air inlet to induct cooling air into the at least one duct, wherein the at least one air inlet is oriented such that forward movement of the vehicle forces air through the inlet; at the second distal end at least one air outlet to exhaust the cooling air from the at least one duct; the at least one duct having, between an air inlet and an air outlet, at least one component of the vehicle requiring cooling; and the at least one duct having, between said air inlet and said air outlet, means to positively draw air through the at least one duct.
