temp guage goes up and down...up and down
And its been going on since it got cold
(so that may be it,double checking to be sure)
Anyway,its got a 180 stat in it and when I warm it in the morning its fine.After I get about 3 miles down the road the stat will suddenly max out and hang for a few seconds (somewhere between 30-60) then drop down to normal.It'll do this 2-3 times on the way to work(about 15 miles).
I've only noticed it in the morning(which is why I thing the outside air temp is involved) and theres never any sounds of "boil over" when its maxed out(the first few times it did it I pulled over to see what was going on).
So could the cold air be causing the stat to try and stick?

Sounds like a sticking thermostat, not exactly due to an air pocket under it. Try replacing it and see where that goes.

But it was only sticking when it was cold out(teens-20's).Today its in the 50's and it's fine.
Should I swap out the 180 for a 190 during the winter?Or is it something I can get away with that wont cause damage?

I bought a failsafe 190 to put on sometime this week.
