Engine Coolant Temperature Gage; Tire Pressure Light - GMC 2010 Yukon XL Denali Owner's Manual

Engine Coolant Temperature Gage

United States
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If you are pulling a 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.
