Sounds like you may have an air lock in the rads - have you burped the system?

Under the coolant filler, lift the thin plastic cover and you will find a chrome D shaped lever on top of the pressure release valve. Lift this lever to its vertical position & run the car for at least 2 - 3 complete heat cycles. A heat cycle is a minimum of 15 minute drive or until the thermostat opens.
Be prepared to top up the coolant if it is an air lock as the level will drop as the air is expelled out of the valve.
