LIQUID-COOLED DIESEL ENGINE REPAIR MANUAL (MS-1055)

Section 13

Cooling System

Briggs & Stratton Daihatsu gasoline and diesel engines use a pressurized, forced circulation cooling system.
The water pump circulates coolant through the cylinder block, cylinder head and radiator. The thermostat maintains

optimum engine temperature.
The thermostat is equipped with a by-pass valve which permits coolant to re-circulate through the cylinder block and

cylinder head.
As the engine warms, the by-pass valve closes as the thermostat opens, permitting complete circulation through the

radiator.
Always maintain a 50% solution of phosphate free antifreeze at all times for adequate heat dissipation, lubrication

and protection from freezing.
