Frequently asked questions

What does the PRC6387 oil pressure switch do?

The PRC6387 threads into the engine oil gallery with an M10x1 thread and monitors lubrication system pressure. When oil pressure drops below the switch threshold, it closes the circuit and illuminates the low oil pressure warning lamp on the dashboard.

Which Land Rover engines does PRC6387 fit?

This switch fits 4-cylinder engines with M10x1 thread: 2.25L petrol, 2.5L petrol, 2.5L NA diesel, 2.5L TD, 200TDi and 300TDi in the Defender, Discovery 1, Series 2/3, Range Rover Classic diesel and Range Rover P38 diesel.

What are the signs the oil pressure switch is failing?

A failing switch typically causes a false low oil pressure warning with confirmed normal oil level. Oil leakage at the thread is also common. Always confirm actual oil pressure with a gauge before condemning the switch, as the warning lamp circuit runs through it.
