Radiator Caps!

[hunterguy92]

Im in the middle of a restoration on my 41 H that still has its original unpressurized radiator. Dang thing was such a pain to get off Id prefer to just go ahead and buy a new one seeing Im this far along and would hate to take everything back apart once the original springs a leak.

Only problem is the original radiator cap is pretty cool looking and Id hate to replace it with a modern pressurized winged cap. Can anyone confirm that the old style unpressurized caps will fit on a new pressurized radiator?

Thank you!

Dont think it will, non pressure caps screw on like a pickle jar.

I thought they screw on like the fuel cap

I got my radiator cleaned, tested and repaired. Many new radiators really are not anything to be excited about - other than being enraged that they don't last.
Not sure if the cap will fit - they look similar to the pressurized ones (although taller) and fit in the same manner.
My Farmall M has a pressure-type cap, but it looks very similiar to the non-pressure type - no wings on it.

Caps are different. Have your old rad checked and cleaned. New ones wont fit right.

The old cap absolutely will not fit the new radiator, but the old cap WILL fit the gas tank.

Search net for number 43983D for a new one if your gas cap and radiator cap is the same size. Several places selling the non pressure type.
