Hello,
Is there a procedure for testing the Oil temperature guage and sender? Mine does not work, the needle never moves from the cold position. Thanks |

are you referring to the factory console gauge? the gauge is basically a voltmeter with the sender acting as a variable resistor. you could check a wiring diagram in a haynes. remove all the pieces from the car, hook up 12VDC to the gauge and stick the sender in a pan of water on the stove with a thermometer to calibrate the gauge.

a factory gauge should peg at fullscale if the sensor wire is open, and min scale if it is grounded.
but this presumes that you have good +12V at the gauge - so check that too. |

With the key on, ground the wire that comes out of the main harness, below the battery box, that is connected to the sender. Wire comes from the Taco Plate, across the engine, up thru the sheet meta near the accel cable to one of those famous Geman kindaplastic connectors (spade terminals). Guage should read full.....if not:
1: You don't have power to the guage 2. Guage is shot (unlikely) If guage works: 1. The above mentioned connector is loose and not making contact 2. Check connection at taco plate and the wire going to it 3. Sender is bad (unlikely) |

I checked everything this weekend. The guage is getting power, I cleaned all of the connections and verified continuity from the guage to the sender. I disconnected the wire from the sender and ground it and the needle was pegged on the hot side of the guage.
I had a continuity problem which has been fixed so I guess it is the sender. Thank you for your help Dan |

My wife thought I was nuts but this is how I tested and calibrated my oil temp gauge.
At least I know its accurate at 212 deg F. Attached image(s) |

That's great. Wives don't get car stuff in the kitchen. I catch hell for using the oven (trailing arms and cam gear). I try to do it when she isn't home but I always get caught.

Any idea on where to get a new sender? I check with Pelican but they have it as NLA?
Thanks, Dan |

Dave,

Sender is bad (unlikely) My oil temp gauge in center console is not working (not moving from 0) and I want to run this this troubleshooting sequence if it is not too difficult to access, while I am on jackstands awaiting front brake renewal. I assume the engine does not need to be dropped to check the "taco plate" area? You access it from under the car behind the driver's seat? |

Yes, it's easy to get at from underneath. Black plate in the forward/left corner of the sump. Green/red wire coming out of it. Note that you have to drain the oil before removing the sender or the plate, or you'll end up draining it unexpectedly...
