Replacing the thermostat, details? Options

[Artega]

My thermostat seems to be toasted.
The car would indicate that it's below the C line even after driving for 30 mins

It would means that the car is running rich and have a high idle to protect the "cold" engine right?

my quesiton is
is there a guide to for thermostat replacement on the GT-four?

I got the ST205 & 3SGTE repair manual supplement pdf
is the thermostat the same as the "intake air temperature sensor"?

Anyone have the parts number for the 3s-gte thermostat?
I come from a pretty cold place so I don't think I'll need a TRD low temp thermostat.

hardly
and not when the temperature gauge shows C

it does blow hot air after driving around for a while, then idle for 5 mins
the gauge would show it's warming up and start blowing hot air
then I would go driving and the gauge would show it's cooled down and no more heat.

so I'm guessing the thermostat is stuck open.
