Oliedrukschakelaar voor de V8 benzinemotor, onderdeel van het waarschuwingscircuit voor de motoroliedruk binnen het smeersysteem.

De schakelaar wordt in het oliegedeelte van de motor geschroefd en bewaakt de smeerdruk, waarbij de contacten worden bediend om het waarschuwingslampje voor de oliedruk op het dashboard te activeren wanneer de druk onder de ingestelde drempel daalt. Het is de primaire indicatie voor de bestuurder van een verlies aan oliedruk.

Frequently asked questions

What does the STC4104 Oil Pressure Switch do on a Land Rover V8 engine?

The STC4104 oil pressure switch threads into the oil gallery of the Land Rover V8 petrol engine and monitors lubrication pressure. When pressure falls below the threshold, it completes the circuit to trigger the dashboard warning lamp, giving the driver an early alert to oil system failure.

Why does the oil pressure switch fail on a Land Rover V8?

The switch typically fails due to a perished internal diaphragm from heat cycling and vibration, causing either a permanently illuminated warning lamp or no warning at all during genuine low-pressure events. A false oil pressure warning on a V8 Defender or Discovery is a common symptom.

How do I confirm this switch fits my specific Land Rover?

This switch fits V8 petrol applications: Defender (1986-2006), Discovery 1, Discovery 2 from VIN XA231750, Range Rover Classic, and Range Rover P38. On Discovery 2, check the VIN. Early vehicles used a different switch. Diesel models need a different part.
