Water Temperature Sensor suitable for JCB - 716/30128

Technical Specification and Compatibility

An essential component of the cooling system, the 716/30128 coolant temperature sensor by NEXGEN. It is a precision sensor, typically screwed into the thermostat housing, designed for JCB machines (incl. Fastrac, Loaders) equipped with Perkins 1000 Series (AK) and Cummins QSB-6.7 TIER 3 engines. It features a 2-pin connector and an M20x1.5 thread, providing an accurate coolant temperature reading for the gauges or ECU.

Related Parts and Hardware

When diagnosing temperature issues, we also recommend checking the condition of the thermostat, thermostat housing (for cracks), the radiator, and the temperature gauge itself.

⚠️ Safety Warning

A failed water temperature sensor is very dangerous. A false reading (showing a cold engine when it is overheating) provides no warning to the operator, which can lead to a cracked cylinder head, blown head gasket, or complete engine seizure. The repair costs will far exceed the cost of the sensor.

Part Role in the Machine and Failure Diagnostics

The 716/30128 sensor is a thermistor – a resistor whose resistance changes with the temperature of the coolant. Screwed into the thermostat housing, it is immersed in the coolant. It sends an electrical signal (variable resistance) to the dashboard gauge or the ECU, informing the operator of the operating or critical (overheat) temperature.

  • › Temperature gauge on the dashboard does not rise (stays on "cold").
  • › Gauge immediately jumps to the red zone on startup (short circuit).
  • › No warning (or false warnings) of engine overheating.
  • › Engine goes into limp mode (if linked to the ECU).
  • › Visible coolant leaks from the sensor's threads.

🔧 Expert Guide: Key Installation Tips

  1. Check Thread and Plug: Ensure the M20x1.5 thread and 2-pin connector are identical to the old sensor.
  2. Clean Mounting: Clean the threaded port in the thermostat housing before screwing in the new sensor.
  3. Sealing: Use the correct sealing washer (copper, aluminum) or a suitable thread sealant to prevent coolant leaks.
  4. Torque: Tighten the sensor with appropriate force. It is a precision component – over-tightening can damage the threads or the sensor body.
  5. Check the Connector: Ensure the electrical plug is clean, dry, and free of corrosion.

Frequently Asked Questions (FAQ)

Does this sensor also fit transmission oil?

In some JCB machines (like Fastrac), sensors with this part number (or 716/28800) are used interchangeably for water or oil. However, you should always verify the part number in the parts catalog for the specific function, as they may have different resistance ranges.

Why is my temperature gauge not working?

The most common cause is a failure of the sensor itself (burnout or short circuit). It could also be a damaged wiring harness (broken wire), a blown fuse, or a faulty gauge on the dashboard.

Where is this sensor typically mounted?

In most Perkins 1000 AK and Cummins QSB 6.7 engines, this sensor is screwed directly into the thermostat housing or nearby, allowing it to measure the temperature of the coolant exiting the engine.
