Pressure Testing





NOTICE During pressure testing, do not exceed the pressure for which the system is designed. The maximum pressure is 102 kPa (1.05 kgf/cm², 15 psi).

Cooling System Flushing

Over a period of time, the cooling system accumulates rust, scale, and lime in the water jacket and radiator. When this accumulation is suspected or observed, flush the cooling system. If this accumulation is not removed, it will clog up the water passage and considerable reduce the efficiency of the cooling system.

NOTICE Do not use a flushing compound which is harmful to the aluminum engine and radiator. Carefully follow the instructions supplied by the manufacturer of the cleaning product.
