Temp Gauge went to max but engine felt normal

Hello all,
I've bee working out of the US for 5 years and finally back for good. When I would return on my R&R's I would start the Cat and it always worked fine. Yesterday I took her out for the first time in 4 months and all was fine, ran great but at one point the gauge pegged at 240 deg. (original gauge). I know the engine was not hot because the second fan had not come on. I can turn it on manually if I want so I did and it did not change the gauge. I stopped and nothing seemed to be too hot. I'm guessing that the sending unit is to blame and not the gauge. Any thoughts?

Thanks in advance

That happened to mine too intermittently. I like you thought it must be the sending unit so I replaced it with one from NAPA. Sorry to say that the problem came back. I replaced the gauge and all is good.

Maybe a sticking thermostat which is why your fans possibly did not turn on? Were your water pipes going to from the radiator normal temps?

Happens to 6018 every once in a while, if I turn-off the A/C the reading returns to normal. Obviously a grounding issue. Since it is intermittent its difficult to troubleshoot. Probably just going to have to go through all the grounds someday.

Thanks all,
Got the sending unit from NAPA yesterday but by the sound of things I'll just live with it for a while and just keep an eye on it. Not really eager to chase grounds just yet, or go through the burping process if I loose coolant on the sender change.
I'm sure the thermostat is good, I can always see the temp rise a bit then drop down so I think all is good there.
Thanks

Oh,
What a blast to drive the cat again, forgot how fun it was. Took my neighbor for a ride, his first time in a Pantera. He wants one now.
