Coolant temperature

Coolant temperature


The coolant temperature gauge provides the driver with information on the engine coolant temperature.

The coolant temperature gauge is supplied with current and controlled from the main instrument unit.

The engine control module sends continuous information on the bus concerning the coolant temperature.

The coolant temperature gauge is divided into 5 fixed break points. The main instrument unit is programmed to move the gauge needle to the fixed break points at specific temperatures in order to provide a stable display at normal coolant temperatures.

The following break points are programmed in the main instrument unit (factory setting):

Gauge needle: Coolant temperature
starts to move 50 °C (122°F) (fixed value)
into "horizontal" position 80°C (176°F)
out of "horizontal" position 115 °C (239°F)
into "red" zone 129 °C (264°F) ("ENGINE COOLANT HOT" shown on SID)
out of "red" zone 133 °C (271°F) (fixed value)
