Temperature Gauge: Description and Operation
Engine Coolant Indication System
The engine coolant temperature indication system is a magnetic-type indication system consisting of:
^
The water temperature indicator sender unit located in the engine block or cylinder head.
^
An engine coolant temperature gauge in the instrument cluster.
The water temperature indicator sender unit operates as follows:
^
Changes resistance according to engine coolant temperature, which varies the current flow through the engine coolant temperature gauge.
^
The pointer position varies proportionally to the current flow.
^
resistance is high when the engine coolant temperature is low, and low when the engine coolant temperature is high.
^
The pointer of the magnetic engine coolant temperature gauge remains in position when ignition switch is turned to OFF.
^
Pointer will move to the correct indication whenever the ignition switch is turned back to RUN.
^
Pointer may indicate at the top of the normal band with the engine coolant temperature within specification, under certain driving conditions such
as heavy traffic or stop-and-go driving in hot weather.
