No change in Radiator water level in last 8 months

The picture below has not changed since 2010, but I take a new one every so often.

The radiator level remains constant and I have not added water for at least the last 8 months.

The benefits of modifying a 28 Chev water pump with modern internals, that still looks very similar on the outside, combined with an overflow tank and a very low pressure sealed cooling system allow motoring in all temperatures with no concern about overheating or loosing water.

In addition by running a very low pressure system I can use modern coolant with anti corrosion additives.

I only would panic if I saw green water under the car.

Cheers
