Hmmm.. over heated a bit.

Got up the O. Odd, never a coolant leak or anything. From sitting over night I left home to a coffee shop to get my morning fix. About an 8 minute drive at most. Car was idling for maybe three minutes. Come out and I see the temp gauge way up. Not enough to trigger warnings.

Since it was humid as heck out I did have the AC on max from the get go.

Could the fan have been cooling the radiator too much to have kept the thermostat closed?

Fan is a couple years old at most and runs fine. T-stat has about 40k miles on it. Actually everything has 40k or less on it. Pump, radiator, etc.

I thought it was my tune, but the fan was set to 190 on a 180 t-stat. I am going to increase it to 200 or 210.

Excluding hardware, any ideas on it being a tune issue? Been using the same tune for a few days and never an issue before.

sounds like an air bubble or a fan not working

Well there was air after over-heating, I dumped a lot in.

Fan seems to work fine. At O it was running at full speed - AC on of off.

i would say air for sure, teh coolant crossover pipe is trickky

if the temp goes up then down it's def. an air bubble. WHY there is an air bubble would be a mystery though.

 

[danny_holtermann]

you eed to let your therm open up, that will allow the air bubbles if any to go up and into the coolant crossover pipe, take the cap off and top it off, do it until there is only coolant in that part of the pipe

check your engine oil level too, when I had a leaky pan gasket I'd see my temp go up when the oil got down a half quart or better.
