Engine Coolant Temperature Gauge - Toyota Tacoma 1996 Instruction 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 over-
heats, stop your vehicle and allow the en-
gine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
S Driving up a long hill on a hot day.
S Reducing speed or stopping after high
speed driving.
S Idling for a long period with the air con-
ditioning on in stop-and-go traffic.
S Towing a trailer.

NOTICE
z Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to
control the flow of coolant to keep
the temperature of the engine
within the specified operating
range.
z Do not continue driving with an
overheated engine. See "If your
vehicle overheats" in Part 4.
Tachometer
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
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.
