Already did that. Brand new one did the same thing; put the old one back in and it did the same thing. The fellow at the shop said I needed a new instrument panel. Funny how it worked perfectly before I did all the work.

 

Did you put thread tape on the sending unit? That will disrupt the ground and give goofy readings.

 

No. I just installed it.

 

Are u not losing any water?

 

No, everything is fine and seemingly working correctly. According to the mechanic, the gauge is not working correctly. Like I said, they took it for a test drive with a scanner and it is cooling correctly. I must have done something when doing the work. Or, it just stopped working all of a sudden. Things do go bad and sometimes all of a sudden.
