Noises problem
2006 Nissan Micra Two Wheel Drive Manual 30,000 miles

Low mileage Nissan Micra, recently serviced has developed an early morning low revs high pitched whistle. If the car is idling (e.g. after you turn it on but before you leave the drive) it is audible and for about half an hour after in low revs, just after a gear change it is also audible. After approximately half an hour the noise disappears, even at low revs. Car also has a cracked radiator neck and is leaking engine coolant, could this be causing the noise?
