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. |

egauges.com lists 10-180 ohms as the resistance range of a VDO temperature sender. If this is true of the stock sender, then my gauge is about right and I just need a new sender. I've ordered the aftermarket sender from Summit ($10) and will see if this works.
