Checking the coolant
We have filled your power generator’s cooling circuit with premium coolant that
ensures long-term material compatibility, and protection from corrosion and frost.
The specification G12+ additive is free of nitrite, amine, phosphate and silicate
and is mixed to ensure frost protection to at least a –25°C ambient temperature.
So as not to impair the protective effect, use only a maximum 50% mixture for
refilling.
NOTICE!
Follow the engine’s operating and maintenance manual for all work on the
cooling system.
In deviation from this, follow these instructions:
► Check the coolant level only from the surge tank (Fig. Fig. 10-3 ) near the ra-
diator.
The fluid level should always be between the Maximum and Mini-
mum marks.
► If the tank is empty, the cooling system must be ventilated!
CAUTION!
Hot surfaces and hot, pressurized fluid. Burn hazard.
► Never open the radiator cap when the engine is running or is hot.
► Before opening the radiator cap, let the engine cool down.
► Open the radiator cap slowly, so that the overpressure in the tank can dissi-
pate slowly.
