Oil pressure switch

[Dagwood83]

What size wrench does it take to get the oil pressure switch off?

It's a like a 1" or something close to that. Local parts store should have a special socket made for it. Socket will slip over and the top has a wrench head that you use another socket on. Has a 3/8 drive but due to fitting other vehicles won't go on a ratchet because the sensor connector interferes

+1 Get the socket, auto zone carries them. The sending units are very cheaply made and break easily, I broke one when I got the wrench on slightly angled and had to buy another one.
