I had a vehicle a while ago ( not a jeep but still )that would peg out the temp gauge but sometimes fluctuate and after checking things out the plastic connector for the temp sender had degraded due to heat and of course being old and the connection was just dirty and corroded.

my temp is running at 210 exactly after driving it but my gauge says it’s running at 180 or even less than that i have replaced the Sender 3 times and tested the gauge with a ground wire and there fine only thing I can think is that the cap on the wire maybe be dirty and it’s also squishy around the cap can that cause it to read cold and what is the best way to clean it ?
