[4] WATER TEMPERATURE GAUGE
Water temperature gauge is located on the meter
panel board.
The water temperature gauge and the thermo unit
are connected by the wiring.
The water temperature gauge detects the resistance
from the thermo unit.
The water temperature gauge indicates the coolant
temperature in the engine cylinder head.
The relationship between the resistance of thermo
unit and reading on the water temperature gauge is as
follows.
• When the coolant temperature stays at 125 °C
(257 °F) for 5 seconds, the indicator on the Easy
Checker™ comes on.
• When the coolant temperature stays above 130 °C
(266 °F) for 5 seconds, the indicator remains on and
all segments of the coolant temperature gauge start
blinking at 1-second intervals.
• When the coolant temperature stays below 120 °C
(248 °F) for 5 seconds, the indicator turns off.
