Normal 186 ECT ?
After a 20 mile drive this morning with the outside temp in the upper 50's I noticed my ECT at 186 and the EOT at 190. I thought the thermostat was 195 ?
Is this normal or do i have a stuck thermostat?
If I am running it other direction, up hill most of the way the ect is 200 to 205.

The thermostat begins to open at about 190*F to 195*F and is not fully open until about 215*F to 219*F.
Your readings don't sound like they are unbelievable to me with the ambient temps you were in.
Where are you measuring the temps?

Those sound about right. They will also fluctuated due to what tunes you are running and how fast you are going as well as ambient temp, but if you are driving normally with just a regular street tune I wouldn't be worried about those temps.
