I'm trying to track down a temperature issue on our 2.0L, and have replaced the gauge and sender. Temp still goes to red (about 280F), within 10 minutes of driving. Temp is actually around 165F from a laser temp reader. Only thing I can think of is wiring.
Am I correct, when I see the wiring diagram showing the Oil temp indicator is the same as the sensor? The diagram shows an "indicator" and a "gauge". I want to run some external, new wires to see if there's a difference. Thanks for any knowledge.  |

The car is a 1974 2.0L. I was pointing the laser at the cases just above the bottom fin area. I also wasn't sure how fast the inside temp of the oil would conduct to the outside of the cases. But, comparing a 10-minute drive to a 30-minute drive, laser temps were the same.
Also, the wiring diagram is stated as a 1974. I believe it's on this site. I will run new wire from the sensor to the gauge and a new ground wire from the gauge to a new ground. Thanks for the feedback. |
