3.4.9 IMPORTANT SERVICE NOTICE

Any time an engine experiences a high coolant
temperature alarm condition the primary cause of the
overheat must be determined and the cause corrected
to prevent a recurring overheat event.. Additionally,
if an event of a restricted flow, collapsed hose,
insufficient coolant level or failed pressure cap is
experienced, further investigation of the cooling
system is required.

1) The coolant shoud be drained (after de-

energizing the coolant heater

2) Replace the engine thermostat(s)

3) Remove the engine water pump and

inspect the impeller and seal for damage, replace as
necessary. Reassemble and refill coolant according
to the Installation and Operations Instruction Manual.

4) Run the engine to verify normal operating

temperature.

3.4.9.1 Cavitation

Cavitation is a condition that occurs when bubbles
form in the coolant flow in the low pressure areas of
the cooling system and implode as they pass to the
higher pressure areas of the system. This can result in
damage to cooling system components, particularly
the water pump impeller and cylinder liners.
Cavitation in an engine can be caused by:

•

Improper coolant

•

Restricted coolant flow caused by collapsed
hose or plugged system

•

Coolant fill cap is loose or unable to retain
the required pressure

•

Insufficient fluid level

•

Failure to de-aerate

•

Overheat
