No, actually you seem to be. A car's thermostat does not open and close while it's running and after it's opened the first time.
The thermostatically controlled fan on your radiator, on the other hand, will cycle on and off in response to climbing coolant temps....comes on at a predetermined temp and turns off at a lower predetermined coolant temp. The thermostat, once open, remains open.
Like I said, you're an idiot... First of all, you're assuming the electric fan is running all the time.
No she isn't, she clearly says that the fan will cycle on and off.
No you are wrong... you just owned yourself again...
To say that a car's thermostat does not open and close due to the hot coolant flowing through the radiator is a complete lie unless you're talking about a malfunctioning vehicle. You have no idea how the cooling system of a car works. Since nobody here wants to argue with me, against you, this only confirms my fears that you people haven't a fucking clue as to what you're talking about.
A (180F) thermostat never closes due to hot coolant flowing through it... just saying...
Hot defined as ~200F
What you meant to say was that a car's thermostat opens and closes due to variances in the coolant temperature. Which is different.
Although it may well oscillate about a variety of open positions rather than closing depending on conditions - eg 0.5 open, 0.75 open, 0.5 open, 0.25 open.
^Under these conditions the thermostat acts as a flow regulator during normal operation. Everyone knows this.
Listen KID, thermostats open when it reaches a designated temperature and close at a designated temperature, END OF DISCUSSION.
BWAHHAHAHAHAHA... a 16 year old calling someone a kid, what will you do next fleabag?
If it doesn't close or doesn't open, then it is broken and somehow you've gotten yourself to believe a broken thermostat is one that is working. You are completely confused as to the purpose of a car's thermostat.
We all know how a thermostat works... and for those that don't this was linked earlier in the thread...

There is also a nice diagram of the processes involved in warming a car up.

Radiators are quite effective in the dissipation of heat without the assistance of a fan which is why in temperate climates, it's very possible for the radiator fan to never come on if it is electric because the radiator is able to cope with the job of dissipating excess heat. The fan is for when the heat output exceeds the ability for the radiator to dissipate heat through regular convection.
Which is why the fan is most likely to come on when you as stuck in traffic...
If the thermostat was stuck open, the car would probably have been closer to 100F and would have a whole host of other problems. You've conveniently avoided the parts where I said you can clearly see when the thermostat has opened and closed.
Why don't you use your fancy gauge to post some data? A nice graph would illustrate the point...
PS... what does this problem sound like to everyone else?
When i am sitting idle my car warms up just fine but when i start to drive the temp drops.
