==== Oil Pressure Sensor / Oil Pressure Switch ====
For 2010 Mercury Milan – 3.0L V6 (Duratec)

Common part numbers (any of these are fine):
* Motorcraft: SW-6350 (most OEM-correct)
* AutoZone (Duralast): PS404
* O’Reilly (Import Direct): OPS104
* Advance (Carquest): S1006

💲 Cost: $15–$40

==== - Passenger side of engine ====
* Toward the rear (firewall side)
* Just above / near the oil filter housing
* One electrical connector plugs into it

If you look down behind the engine on the passenger side, you’ll see:
* An unplugged connector
* A hole or broken metal stub where the sensor snapped

==== - Deep socket: usually 27mm (1-1/16") for the sensor ====
* Bolt extractor / easy-out (for the broken threaded piece)
* Ratchet + short extension
* Penetrating oil (PB Blaster / WD-40)
* Thread sealant (only if new sensor isn’t pre-coated)
* Shop rags

==== ### ====
# Spray penetrating oil — wait 5–10 minutes
# Insert bolt extractor into the broken metal stub
# Turn counter-clockwise
# Go slow — the block is aluminum

⚠️ If it won’t budge → stop and take it to a shop (cheap fix, prevents stripped threads).

===== 1. Light thread sealant (if needed) =====
# Thread in by hand first
# Snug tight — do NOT over-tighten - About 12–15 ft-lbs (hand-tight + a small turn)

===== 1. Plug electrical connector back in =====
# Check oil level (top off if needed)
# Start engine
# Oil light should go off in 1–2 seconds

==== - DIY time: 30–60 minutes ====
* Shop time: 20–30 minutes
* Typical shop cost: $80–$200 total

==== - ❌ Do not drive until fixed ====
* ❌ Do not overtighten the new sensor
* ❌ Do not reuse the broken one

==== This is a very common failure on the 3.0L V6. ====
You caught it before engine damage — that’s a win.

If you want, tell me:
* Do you have basic tools?
* Is the broken piece still stuck in the engine?

I’ll tailor the next steps exactly to your situation 👍
