Default 81 engine, let's play guess that sensor.

The sensor on the passenger side of the engine towards the rear of the head, has 2 prongs on it, 3/8 npt. I know the oil sender is on the back-top of the block, oil temp is over the oil filter, and coolant temp is drivers side head - front. I looked in the service/AIM and there was no clear definition of what that sensor is. Please excuse my brain cramp :D

On my 79 that is for the aux cooling fan. Not sure if it is the same on an 81.

I'll go along with Pete79 on that one. There's also a temp coolant sensor (for the ECM) on the front of the manifold. The one on the driver's side is the temp sender for the gauge.

Pete & Chris - THANKS! I should have thought of that, but when all that's left in your engine compartment is hanging wires it's a little hard to picture some of it.

You could say that :eek: I had taken a bunch of pictures when I pulled the motor, then I went crazy and cleaned, sandblasted, sanded, painted everything in sight. Problem is that my hard drive failed and I lost ALL the pictures.

Wouldn't happen to have a pic of the radiator support showing the seal locations handy would you? The AIM and shop manual dont show this very well :D :lol:

I'll head to the garage and shoot some pics for you. That's a bummer losing all your pics! :smash:

Chris,

You are the man! Many thanks, but don't rush as I have a couple more days before I get the motor started. :cheers:
