5-10 min is not abnormal at all to reach normal operating temperature. If your thermostat is stuck in the open or partially open position your engine temperature may not reach normal operating temperature specially while driving at speed. Observe your engine temperature while the car is moving versus while the car is at a stop. If your engine temperature rises while at idle and the engine temperature decrease while moving is a good sign the thermostat is stuck open or partially open.
