Frequently Asked Questions

Is my low-oil-pressure warning real?

Verify with a mechanical gauge. If pressure is good and the switch is weeping or corroded, the switch is the fault.

How do I test the oil pressure switch?

Fit a mechanical gauge to confirm the engine actually has pressure. If the pressure is good but the warning light stays on or the switch weeps, the switch is the fault.

Where does the switch thread in?

It threads into the engine oil gallery. Confirm the style against the listing photos, and verify real pressure with a gauge before trusting the light.
