what are these engine sensors for on my GM block?-gctid823337

[Centerline2]

the sensor at the top rear of the block is the oil pressure sender, but I dont know what the one above the oil filter is for.... is it a switch for low oil alarm? as the single wire that is connected to it, also runs to what I assume must be a high temp alarm... when either get out of the "safe" range, the sensors trip the alarm?

I would like to replace it but I dont know what it is for sure or what pressure range it should be.... thanks for any help

Yes, low oil pressure switch

+1 and yes the alarm for low oil pressure and hot temp are wired together, if either closes the alarm sounds.

My alarm buzzer was acting goofy and both my temp and oil switches were not operating correctly (both stuck closed)

I replaced everything with this kit, works great and save some $$
