G'day all,
I have a 2001 GU 4.2D Nissan wagon. The top radiator hose and overflow hose is getting a white powdery coating on it. I wipe it off but the next time I open the bonnet the pipe is white again.
I have only ever used Nissan coolant. The coolant was changed about 12 months ago. The coolant level does not drop.
Has this happened to anyone else ? Has Nissan changed it's coolant formula, or are the radiator hose and overflow hose telling me that they need replacing ?
Thanks in advance .. Cheers Pete.
