No need as that is the job of the thermostat.
However I can see that operating temps being lower than you want. For example on one of my cars the T-stat opens at 170F. But the car should operate at 190. When it is cold out side the car has a hard time getting there.
A trick is to slip some card board between the two radiators. The front rad is for the AC and the rear is for the cooling system. Being in a wet climate you might use some flexible cutting board material or thick plastic sheeting.
But if you jsut want quicker warm ups, this would not help. Block heater (or oil dipstick heater) on a timer, park in garage are your only real options.
