I may have messed up . The '87 2.9 motor I'm rebuilding had a fitting in the left side of the oilpan that accepts a "single-wire" probe of some sort. ( Very close to the starter). Whats it for?

I'm guessing a oil temp probe?

I'm going back together and hope I can I do without it? I ask because...not knowing what it was for, I removed the fitting from the pan and sealed it off by welded a blank disc over the hole. Too late to turn back now.

Thanks, Dave

yeah it is for the low oil (check oil) idiot light. when i swapped motors mine got cut... just check your oil often.

Wow, I did'nt know the Bronco had a "check oil" light.

So it senses a low level ? ? . . . . not hot oil?


And so I don't have a constant idiot light on, do ground the wire or tape it off?

Thanks, Dave



Man, i gotta get my lazy butt moving and finish this motor ! I was the guy asking a bunch of questions about 2.9 rebuilds.....LAST JULY !

yeah when my oil was low and my truck started getting hot the light would come on but since the motor swap and me not hooking that wire back up it hasn't blinked, flashed, stayed on, or even thought about coming on really...
