Oh ok Al . They are normally good .
No mechanical fan with an electric waterpump whistling
Like I noted check air flow out of engine bay . Do you have a scoop ?
I have seen cars in the shop with aftermarket electric fan shrouds to have airflow reduction . That is why some euro cars have flaps on the shroud , lets plenty of airflow at speed .
If the car is idling bonnet shut from cold does it quickly or slowly build up heat ? ie does it take 5 mins or so to get to 200F or 15-20 mins ? or longer ?
