Coolant Temperature Gauge
The coolant temperature gauge indicates engine coolant temperature. The normal
operating temperature for Volvo engines is 80 to 105°C (170 to 215°F). Under normal
driving conditions, the temperature must be below the red sector.
The temperature range for the coolant will vary depending on the type of engine, load,
grade, ambient air temperature and operating conditions. If the temperature remains
below or exceeds the normal temperature range, the cooling system should be checked
for problems by an authorized Volvo Truck dealer.
The temperature limit is dependent on the electronic program for the engine model.
When coolant temperature is excessive, the red STOP tell-tale will come on and the
buzzer will sound. The engine is at risk and the EECU may derate the engine power.
Stop at the first safe place where the problem can be checked.
W3005171
Stop Tell-Tale
If the coolant temperature returns to normal shortly after exceeding the limit and no
repair is performed, the warning messages go out, but a fault message will be logged.
Middle and Lower Tell-Tales
The middle and lower tell-tales provide vehicle and component status information.
For more information, refer to the Driver Information Display manual.
Driver Information Display (DID)
The DID gives the operator necessary and important information about the vehicle
and components. For more information about the DID, refer to the Driver Information
Display manual.
Fuel Level Gauge
The fuel level gauge is connected to a fuel sensor unit in the fuel tank. There is only
one sensor even if the vehicle is equipped with dual tanks.
