Engine Coolant Temperature Gauge - Mercury Grand Marquis 2002 Owner's Manual

Instrument Cluster

Engine coolant temperature gauge

Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the area
between the "H" and "C"). If it enters the red section, the engine is
overheating. Stop the vehicle as soon as safely possible, switch off the
ignition and let it cool. Refer to Engine coolant in the Maintenance
and specifications chapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
Standard instrument cluster
Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant and Check Engine/Service Engine Soon indicators illuminate,
refer to What you should know about fail-safe cooling in the
Maintenance and specifications chapter.
