Fluttering temp guage?


#1

On my '95 Ciera, the temperature gauge will be reading normal (middle of range,) then will suddenly bounce very rapidly back and forth toward the hot end of the range. After a couple of seconds, it will return to reading normal.

I noticed the same thing happening the other day after I had only driven a mile or two and the engine wasn’t yet up to normal temp…

I’m guessing that it may be a malfunctioning temp sensor, or could it be just a bad electrical connection?

Any other ideas? Your input is appreciated. :slight_smile:

Check the coolant level in the radiator (when it’s cold), then clean and tighten the connection at the the temp sensor. If that doesn’t work, try a new sensor.

Coolant level is OK. I’ll check the commection when it stops raining. :slight_smile:
Thanks!
