7.3.5 Checking the coolant level
If the symbol appears on the display, you must top up the coolant.
Topping up the
coolant
• Do not open the pressure relief valves (2).
• Loosen (do not open) the cap (1) to reduce
the pressure if the coolant is at operating
temperature.
• Open the cap (1).
The coolant level must be at the lower
marking in the filler neck.
If the coolant level is too low
• Top up the coolant.
Composition of the coolant;
à Engine manufacturer's documentation.
• Close the cap (1).

The cooling circuit also feeds the heat exchanger on the transmission with
Intarder (additional equipment);
à Transmission variants, p. 7 - 41.
G
Danger of being scalded due to hot cooling circuit!
The hot cooling circuit is under pressure. When you open the expansion
tank, you can be scalded by escaping steam/coolant.
Wear suitable protective gloves and cover the cap on the expansion tank
with a rag before opening it.
Turn the cap slowly to the first detent in order to allow the pressure to be
released.
S
Risk of damage to engine due to lack of coolant!
If the coolant has to be topped up frequently, the cooling system may be
leaking. Have the cooling system checked by
Manitowoc Crane Care or an
authorised GROVE dealer or your repair crew.
