Hi Steve,
We are not pursuing any further fault-finding until Lida has given the garage's MD an opportunity to respond to her written complaints since this could jeopardise any proposed corrective action.
At present the evidence points to the thermostat since the bottom radiator hose remains tepid. I therefore don't suspect the coolant temperature sender. The garage's technique for diagnosing this, measuring the coolant temperature in an open expansion tank with the engine stopped and cooled down, is unsound.
