COOLING SYSTEM 4-9
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.
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.
•
Warm up the engine, and run it at normal operating tem-
perature for about ten minutes.
•
Stop the engine, and drain the cooling system.
•
Fill the system with fresh water.
•
Warm up the engine and drain the system.

Repeat the previous two steps once more.
•
Fill the system with a permanent type coolant and bleed
the air from the system (see Coolant Change in the Peri-
odic Maintenance chapter).
