Radiator Cap

[Eleven]

Remembering Jan's remarks about radiator caps, I checked mine because I lose water with not much driving. I have a 3/4inch cap, it doesn't seal. I bought a 1 inch cap but it will not go on, a hair too long. I think my radiator is stock but have no way of really knowing. Is there such a thing as a 7/8ths inch reach cap? (Last cap I bought came from SS and was marked as the correct one) If anyone has this issue and a part number, thank you!!

In my book of notes from all of these forums, I see that a radiator cap for a 1939-1952 Ford tractor, part #0237518, will work. The only thing is I didn't note if that was a Ford number or NAPA, or what. Also since I own a Series II, it might be specific to that model. Sorry I can't be more help.

I bought a Stant replacement 7psi cap at one of the local auto parts chains, seems to fit.

The Stant website even lists Alpines in their catalog, part# 10206

Here's the dimensions: http://info.rockauto.com/Stant/Detail.html?10206.jpg

If you fill the radiator to the very brim, you will always lose a little coolant as soon as you reach operating temperature as the warm coolant expands. Since there is no expansion/recovery tank, when the engine cools the level will be lower as that lost coolant is not sucked back in like a modern car.

I'm having a coolant loss problem also. so if I install a "tank" for the over flow would I just stick the overflow hose into it(to the bottom) ? Or is there more to it ?

Thanks, Tom j

Overflow

Tom,
Sticking the overflow tube into a "tank" will catch the coolant, but the coolant will not flow back into the radiator (after it cools off) unless you switch to a cap designed for a closed cooling system (which is what you really want). These caps are easy to come by, any competent auto parts store should be able to fix you up.

I haven't yet been able to find a suitable "recovery" cap for my SeriesII. It needs to be one of the "long" caps, and 7lb. The only recovery caps I can find in Australia (CPC) are "short" 7lb caps, or "long" 14lb caps. Anyone know a part number or supplier in Aus?

Thats the long and short of it
