Default Re: Foaming/cavitating coolant in my 34

You need Skips 3 lb valve to keep the water in the radiator.
Don't do that! I had one of his valves, it seized close within a month and damaged my radiator. The valves he use do not appear to be for fluid use, more like a vacuum valve.

I had (have) the same problem as you, with the stock 4:11 gearing anytime I got over 55 MPH it pumped water out of the radiator overflow. A Columbia rear solved that one! I should mention I have Skips pumps, don't know if would happen with stock but Skip said his '35 pumps flow no more than the stock ones.
