My temperature gauge always reads at the left extreme of the scale. While I'd like to think my engine is always running cool, I don't believe it.
I measured the sensor. It measures 2.3K ohms cold and 300 ohms hot. I checked the gauge. 300 ohms barely moves the needle. It takes a resistance of 50 ohms to get to full scale. Does anyone know what the correct resistance range is? I suspect I have the sensor for the aftermarket VDO gauge hooked up to a stock gauge. Pelican wants $30 for an OE senso while the aftermarket VDO sensors at $10 at Summit. Anyone know a less expensive solution? It would be cheaper to replace the gauge - the VDO gauge is $25 at Summit, but the 2.062 inch gauge won't fit into the 60mm hole (2.362 inch) in my center console. |

You need to make sure that you get a sender that matches your gauge. The older gauges use a hotter sender, the later ones a cooler one.
The older senders are NLA, and what is being made new are 150' C senders. If your gauge pegs at 300' F, this is what you want. If you have an older gauge, the 150' C sender will not be accurate. *All of this information is assuming you are referring to the oil temp sender* |
