Datsun 1200 comes with a full temperature gauge in the dash, controlled electrically by the Thermal Transmitter (sender) that is screwed into the cylinder head.

Instrument Panel Gauge
Also see:
- Water Temperature Gauge in Instruments and Controls
- Radiator, section Temperature
Dash gauge. It is not unusual with any 10-year old stock radiator for the temperature to rise during summer. If you have this, don't panic. The engine can run all day close to the "H" mark. Just don't let it go over that.
Normal Temperature
According to Owner's Manual: Water Temperature Gauge, this is the normal range.
Normal Range
Part Number
- 24880-H1000 GAUGE-water temperature JDM [kaku]
- 24880-H1000 GAUGE-water temperature B120 -7803
- 24880-H1800 GAUGE-water temperature JDM [maru]
- 24880-H1800 GAUGE-water temperature B120 7804-
- 24880-H1800 GAUGE-WATER TEMP USA [round gauge]
- 24880-H3100 GAUGE-water 1972 JDM
- 24880-H5500 INDICATOR ASS'Y-water temperature JDM B210
Voltage Regulator
The instrument panel voltage regulator is integrated with the Temperature Guage and is not sold separately. This regulates:
- temperature gauge
- fuel gauge
- 24880-H1000 METER ASSY-WATER TEMPERATURE -7803
- For round and rectangle gauge panels
Thermal Transmitter
The temperature sender (sensor) is called the thermal transmitter. If varies resistance according to temperature.

Transmitter is at very front of right side
Tranmitter at left side, pointing up> it has a threaded collar nut to hold it in.

Troubleshooting
First, clean the connections of the wire to the thermal transmitter (engine temp sensor).
Yellow wire just about hose clamp
Remove the wire and clean the connector. Replace. Make sure the wire fits tight.
- If both fuel and temperature gauges do not work at all, the fuse is likely burnt out. Inspect the fuse. If the fuse is good, the instrument panel voltage regulator may be bad
- If both fuel gauge and temperature gauge read incorrectly (high or low) or fluctuate, the problem is likely the shared instrument panel voltage regulator. But first check the wiring connections. They may be loose or corroded.
- If gauge reads MAX hot with ignition OFF, gauge is defective.
- If gauge reads MAX hot with ignition ON, but cold with ignition OFF, transmitter is bad
- Ground sensor wire at engine. If gauge fluctuates, gauge is bad
Accuracy Test
- Buy a 116-ohm resistor at Radio Shack or other electronics store.
- At the engine, locate the thermal transmitter:
- Pull the wire off the transmitter and put a 116-ohm resistor from the wire to earth/ground
- Turn IGN switch to "ON". Gauge should read 50C/122F, or between C and H ranges (in middle range)
