Just installed my H2O temp gauge, wondering what kind of temps are you guys running out there? Just want to compare notes, thanks.
Mine sits at 180 F at night and 190 in the hot afternoon.

 

Sounds normal. I think that the stock thermostat is 180 degrees.

 

Where do you live? The only time my car runs near 180 consistently over a period of time is cruising at about 70 mph in fifth when it's 60 degrees or colder out. In stop and go traffic in the summer, I've seen the temp get as high as 230, but I've got a fan switch that keeps the coolant down at around 200-205 if I leave it on all the time. I try not to let the temp get higher than 210, that's when I kick the fans into hi.
