Engine Coolant Temperature Gage; Tire Pressure Light - Chevrolet 2010 Avalanche Owner's Manual

This gage shows the engine coolant temperature.
It also provides an indicator of how hard the vehicle is
working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If the vehicle is pulling a
4-34
load or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates that
the cooling system is working beyond its capacity.
