Abstract
An improved thermostat arrangement for an internal combustion engine and an associated cooling system for the engine. The thermostat is designed so as to introduce a swirl in the thermostat housing to reduce pulsations in the coolant. In addition, the engine disclosed has its cooling jacket in such a way that the water pump is at one end of the engine and the thermostat is at the other end of the engine so as to facilitate transverse mounting of the engine.
