NOTICE
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.
Do not continue driving with an overheated
engine. See ªIf your vehicle overheatsº on page
165.
TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine turning too fast causes excessive
engine wear and poor fuel econmy. 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.
