Frequently asked questions

What does the Oil Pressure Switch do?
The Oil Pressure Switch monitors engine oil pressure and completes the dashboard warning-light circuit. It threads into the engine block oil gallery and switches the low-oil-pressure warning lamp on when pressure drops below the safe operating threshold, alerting the driver before damage occurs.
Which Land Rover engines does this oil pressure switch fit?
This oil pressure switch fits early Land Rover Series models, covering Series I 2.0L petrol and diesel, Series II and IIA 2.0L and 2.25L petrol and 2.0L diesel, and Series III 2.25L petrol and 2.6L six-cylinder petrol engines. Confirm the thread matches your existing sender before ordering.
What are the signs of a faulty oil pressure switch?
A faulty oil pressure switch typically shows as a warning lamp that stays on with the engine running and healthy oil pressure, or one that fails to light at all. Oil weeping from the switch body is another common sign. It's an electrical sender, so a failed unit doesn't affect actual oil pressure.
