Engine Coolant Temperature Gage; Transmission Temperature Gage - GMC SIERRA 2002 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.
See "Engine Overheating" in the Index.
