The sensor is located right next to the thermostat. Very easy to change out. The only place that you will be able to obtain the sensor and gaskets are your Volvo dealer. Good idea to replace BOTH items when one fails.
p.s. you might try NAPA for a sensor............they might have that part although I doubt it.
