COOLING SYSTEM: GENERAL INFORMATION
The cooling system uses a water/antifreeze coolant to carry away excess energy in the form of heat. The cylinders are surrounded by a water jacket from which the heated coolant is circulated by thermosiphonic action in conjunction with a water pump, driven off the oil pump.
The hot coolant passes upwards to the thermostat and through to the radiator (mounted on the frame's front downtubes to take maximum advantage of the passing airflow).
The coolant then flows across the radiator core, where it is cooled by the passing air, down to the water pump (via the left frame tube) and back up to the engine where the cycle is repeated.
A thermostat is fitted in the system to prevent the coolant flowing through the radiator when the engine is cold, therefore accelerating the speed at which the engine reaches normal operating temperature.
A thermostatically-controlled cooling fan is also fitted to aid cooling in extreme conditions.
The complete cooling system is partially sealed and pressurized, the pressure being controlled by a valve contained in the spring-loaded radiator cap.
By pressurizing the coolant the boiling point is raised, preventing premature boiling in adverse conditions. The overflow pipe from the system is connected to a reservoir tank into which excess coolant is expelled under pressure.
The discharged coolant automatically returns to the radiator when the engine cools.
