PRC2506 - Water temperature sensor white by AllmakesElectrical Part Land Rover Range Rover Defender, Range Rover

PRC2506 - Water Temperature Sensor – White – 3.5 V8

Q: What does the white water temperature sensor do?

The white water temperature sensor is a coolant temperature transducer that threads into the thermostat housing on the 3.5 V8 carburettor petrol engine. It measures coolant temperature and sends the signal to the dashboard gauge, giving the driver a reading of engine operating temperature.

Q: Which Land Rover does this temperature sensor fit?

This sensor fits the Land Rover Defender with the 3.5 V8 twin-carb petrol engine up to VIN WA159806, and the Range Rover Classic 3.5 V8 carburettor petrol from 1971 to 1986. Check your VIN against that ceiling on Defender, as later builds use a different sender.

Q: How do I know this is the right sender for my thermostat housing?

This is the sensor with the white body, which distinguishes it from the other senders fitted to the same thermostat housing on the 3.5 V8. Match the white colour and the PRC2506 part number against your original, as the housing can carry more than one similar-looking transducer.

Q: What are the signs the temperature sensor has failed?

A failed water temperature sensor typically shows as an erratic, stuck or dead dashboard temperature gauge on the 3.5 V8. Because it feeds the gauge rather than the ECU, a fault usually affects the reading rather than running. Check the wiring and the sender before replacing.

Aftermarket: Quality alternative. This is a quality alternative, designed to fit and function like the original part, often at a more competitive price.

Water Temperature Sensor (coolant temperature transducer) that threads into the thermostat housing within the engine cooling circuit.

The transducer measures coolant temperature and signals it to the dashboard temperature gauge, giving the driver a reading of engine operating temperature. It is identified by its white body, which distinguishes it from the other senders fitted to the housing.

Specified for the 3.5L V8 carburettor petrol engine.

Vehicle Model Land Rover Defender up to 2016
Range Rover Classic up to 1994
