A knackered termostat will dump the temperature considerably on the TB, I drow mine home in the month of february when I bought it and it had an open (knackered) termostat, I almost did freeze
Start the car when engine is cold and feel the radiator top hose, the hose should stay rather cool until termostat opens (around 80-90 degrees), if the hose warms up gradually termostat is bad.
