gages and sending units

[92astro]

ok i just have a couple of questions! first the oil pressure sending unit is located by the dist. right it looks like it? also i found the engine temp. sending unit for the gage it has one wire going to it right? it is green. okay here is my next question: on my gage cluster it is the analog one when i put the key in i turn it to on i hear the fuel pump prime good and i see 3 lights on battery, ses, and seatbelt is there suppose to be more lights on before i start the engine like a bulb test? the van starts and runs great the 3 lights go out after i start the engine so no problem.this is a 1992.

If you mean the oil pressure switch, then Correct. The oil pressure switch is located by the dist. I can take a picture of how the one in my 1991 astro looks like since i had to change it out today? Correct, the 3 lights that light on my cluster is the Battery, SES, and the seat belt when i turn the key.

The oil pressure switch control the pressure to a preset limit, so if the oil pressure increase's it bleeds off the pressure to the pre-set limit. If the pressure drops, the switch turns off the fuel pump, to stop the engine and limit damage to internal parts.

Yea, Those are the only 3 lights that light up when i switch the key.

okay thank-you yeah that is what i saw by the dist. cool also where is the oil pressure sending unit for the guage?

[Smiliesafari]

Oil pressure sending unit and oil pressure switch are the same gizmo.

Oil pressure sending unit and oil pressure switch are the same gizmo.

on my brothers and my old 92 they are different animals . is there a round looking sensor on the back side of the block just below the oil pressure switch ? if there is then that is your sending unit for the gauge . i'll see if i can find a pic for you .


the circled sensor is the one i'm talking about

[92astro]

hey that looks like my engine!!.. have you been taking pics of my engine without my premission?..!!! just joking!!!

[sfeaver]

That sensor that is circled is the knock sensor, not the temperature sender. The temperature sender for the gauge will be in one of the heads i believe.

yeah i know where the temp. sender for the gage is located i found it it only has one wire which is green right? this a 1992 astro. also i am looking for the oil pressure sending unit?
