Not quite!
Yellow circle is the pressure switch, correct.
Red circle is NOT the thermostat, it's another oil temp sensor and sits on the oil breather cap.
The thermostat is located right above the yellow circle under the oval plate with 2 small nuts, partially visible.
The thermostat is mechanical and sits under the oval plate.
It acts similar to a radiator plug. It's about the size of a large egg and is sealed with an O-ring which can leak.
The breather cap seal, oil thermostat O-ring and oil pressure switch are the usual suspects when leaks occur in that area.
That's why I recommend to do an easy partial drop and replace all three items.
It's cheap insurance!
