4-8 COOLING SYSTEM
Coolant
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 cool-
ing system. If this accumulation is not removed, it will clog
up the water passage and considerable reduce the effi-
ciency of the cooling system.
•
Drain the cooling system (see Coolant Change in the Pe-
riodic Maintenance chapter).
•
Fill the cooling system with fresh water mixed with a flush-
ing compound.
CAUTION
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.

Warm up the engine, and run it at normal operating tem-
perature for about ten minutes.

odic Maintenance chapter).
