Engine Coolant Temperature Gage; Transmission Temperature Gage - GMC Sierra Classic 2007 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.
See Engine Overheating on page 501.
