Default 1971 radiator coolant overflow
I have a 307SBC and noticed that it doesn't have a radiator coolant overflow. There's a hose underneath the radiator cap, but it just runs towards the floor. Did they use a tank back then?

I don't think they did but I never owned an early 2nd gen,I can tell you my '72 GMC 3/4 ton 4X4 doesn't have one and never did,my Dad bought it new so I know it's all original.

It's not missing, they never came with one on 71.
You also don't fill the rad to the top. About 2" below the top is full.

Coolant in intake overflow disappears too fast-its cap does not close tightly...
