Frequently asked questions

What does the Oil Pressure Switch 90519864 do on a Land Rover?

The oil pressure switch threads into the engine block oil gallery and monitors engine oil pressure. When pressure drops below the safe threshold, the switch completes the warning lamp circuit to illuminate the dashboard oil pressure warning light. It fits Series I (2.0L petrol and diesel), Series II/IIA (2.0L and 2.25L petrol), and Series III (2.25L petrol and 2.6L 6-cyl).

What are the signs that the Oil Pressure Switch needs replacing?

A faulty oil pressure switch typically shows as a permanently illuminated oil warning light at normal operating temperature and pressure, or conversely, no warning light when oil pressure is actually low. The switch can fail due to internal diaphragm cracking or contact contamination, giving a false warning rather than a true oil pressure problem.

What cross-references are available for part 90519864?

Cross-references include BR 1628, 90519864A, 505152, GPS102, 240526, and JM-99597. Before fitting, confirm the thread type matches your engine block, as oil pressure switch thread specifications varied across the Series engine range.
