GMC sierra 2002 Manuale Utente

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.

Your vehicle may be equipped with a transmission
temperature gage.

When your ignition is on, the gage shows the temperature
of the transmission fluid. The normal operating range is
from 100

_F (38_C) to about 265_F (130_C).
