I recently had a full service performed, including new coolant.
I have to admit I rarely glance at my analog guages knowing I have idiot lights, at least on level ground. In the mountains I watch temp like a hawk.
SO after the service, I started paying close attention in case there was a air pocket, etc.
I noticed that sometimes the gauge was in between cold and straight up and five minutes later, just left of straight up. I keep watching it and it cycles back down.
It does this on a 3-5 minute cycle; goes down, slowly climbs back up, then slowly goes back down. All on flat ground.
I checked coolant level and its full. It acts like the fan clutch kicking in but I never noticed it before.
Anybody elses do that? Its about 70 out today when it was doing it.
