Motor Grader Temperature Gauge – Sender and Range Identification
This motor grader temperature gauge must be matched to both the instrument panel and the temperature sender. The original listing does not show a verified part number, so the gauge label, system voltage, display range, terminal arrangement and sender resistance characteristics should be confirmed before ordering.
A gauge that fits the panel opening may still indicate incorrectly if its electrical range does not match the sender. Diagnose the complete circuit rather than replacing the display solely because the needle reads high, low or not at all.
Electrical information to record
| Product type | Motor grader temperature gauge |
| Part number | Not shown in the existing record; verification required |
| System | Instrument panel / temperature monitoring circuit |
| Critical checks | Voltage, range, sender curve, terminals, illumination and mounting dimensions |
Machine voltage and instrument-panel supply voltage.
Gauge face range, scale units and warning zones.
Manufacturer label and every terminal marking.
Sender part number and resistance readings at known temperatures where the service procedure permits.
Panel opening diameter, bezel size, body depth and retaining method.
Connector type, pin positions and illumination wiring.
Diagnosis before replacement
Check supply voltage, ground quality, connector condition and wire continuity. A shorted sender circuit can force some gauges toward one end of the scale, while an open circuit may send it toward the other; the exact response depends on the system design. Compare readings with the machine diagnostic procedure and a known temperature source.
Protect the engine, not only the gauge
If overheating is suspected, verify coolant level, airflow, belts, thermostat operation and actual coolant temperature. Do not assume an abnormal reading is only an instrument fault. Conversely, a normal-looking gauge does not replace scheduled cooling-system inspection.
Installation and functional test
Disconnect power according to the machine procedure, label wires before removal and protect the panel from short circuits. Install the correct retaining hardware without distorting the gauge body. After reconnection, test illumination, cold indication and controlled warm-up response while monitoring actual temperature through an approved method.

FAQ
Can any gauge with the same diameter be used?
No. Voltage, scale, sender resistance curve, terminals and panel depth must also match.
Does a full-scale reading always mean overheating?
No. A wiring short, sender fault or ground problem can affect the reading. Verify actual temperature safely.
Can the sender and gauge be tested separately?
Use the machine service procedure and approved test values. Avoid applying uncontrolled voltage or resistance.
Why photograph the terminal markings?
They help confirm supply, ground, sender and lighting connections and reduce rewiring errors.
Compatibility note: Final selection requires machine identity, gauge label, voltage, scale, sender characteristics and mounting dimensions.
