Engine Coolant Temperature Gauge - Toyota Supra 1997 Manual

Engine coolant temperature
gauge
The gauge indicates the engine cool-
ant temperature when the ignition
switch is on. The engine operating
temperature will vary with changes in
weather and engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
D Driving up a long hill on a hot day.
D Reducing speed or stopping after high
speed driving.

D Idling for a long period with the air con-
ditioning on in stop-and-go traffic.
D Towing a trailer
NOTICE
_ Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
_ Do not continue driving with an

overheated engine. See "If your ve-
hicle overheats" in Part 4.
Tachometer
The tachometer indicates
speed in thousands of rpm (revolu-
tions per minute). Use it while driving
to select correct shift points and to
prevent engine lugging and overrev-
ving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
