WARNING
Non-compliance can result in serious injuries or death!
The cooling system must be designed so that operating temperatures will not exceed
the maximum values.
Coolant types
It is important that the coolant circuit is designed so that the coolant does not reach boiling
point under any conditions. If the temperature exceeds the boiling point, the engine can
quickly overheat due loss of coolant.
The boiling point of the coolant is mainly influenced by:
• the type of coolant
• mixture ration (percentage water rate)
• the system pressure (opening pressure of radiator cap)
For permissable coolant types see SI-915i-001, latest issue.

To ensure proper operation of the cooling system, the expansion tank with pressure cap in
the main operating systems must be installed on the highest point of the cooling circuit.
