Frequently asked questions

What does the 4346360 coolant temperature sensor do?

The 4346360 coolant temperature sensor monitors engine coolant temperature and sends a signal to the engine management system. The ECU uses this to control fuel delivery, ignition timing and cooling fan operation accurately as the engine warms up.

What are the signs this sensor needs replacing?

A failing coolant temperature sensor typically causes poor cold starting, an erratic or inaccurate temperature gauge, cooling fans running constantly, and higher fuel use. A fault code for the coolant sensor circuit is also a common indicator on these engines.

Where is the coolant temperature sensor located?

The sensor usually sits within the cooling system pipework, around the thermostat housing area where it can read coolant temperature directly. Exact position varies by engine, so check the housing and outlet pipes on your specific unit.

Which engines and models does it fit?

It fits a wide range of petrol engines (2.0 AJ200/AJ20P, 3.0 SC V6, 5.0 V8 AJ133) and diesels (2.0 AJ20/AJ21D4, 2.7 and 3.0 V6) across the listed Land Rover and Range Rover models. Confirm by engine code or VIN before ordering.
