Coolant Temperature Gage


The Coolant Temperature Gage also operates the same as the Fuel Gage and Oil Pressure Gage.

Resistance controlling the coils (Hot coil and Cold coil) is provided by the Coolant Temperature Sender through the DK GRN (35) wire. However, with a coolant temperature of 40°C (104°F), resistance of the sender is high (1365 ohms). With a coolant temperature of 125°C (257°F), resistance of the sender is low (55 ohms).
