Well after 12 weeks of work replacing rusted floor and sill sections, yesterday my car went back on the road for it's maiden voyage on Australian roads.
I picked a great day for it too, 35 degrees and a hot Northerly blowing.
Now the old girl didn't like the temperatures which is why I wanted to ask a few questions about the cooling system.
The car has a new alloy radiator and a set of 12" electric thermo fans fitted. They are rated at 880cfm. Both the radiator and the fans came from Summit racing equipment in Nevada. The water pump was replaced at the same time and it uses an Edelbrock 8844 series high volume pump.
The tanks in the engine bay appear to be original, and are chromed finish, but have obviously leaked at some point as there is evidence of solder on top of both tanks. Not currently leaking though.
Both tanks have pressure caps on them.
Driving the car yesterday the temp gauge reached 210 degrees F and when I stopped the car, there was water coming out from under the pressure cap on the smaller of the two bottles and dripping onto the headers.
Can somebody please explain how the system works and what both tanks are for. Should both have pressure caps, and should they both be full of water?
