Turning to the experts even tho it's not a Hudson......

Does anyone here know if the radiator cap on a 1940 Packard 120 should be a "Filler cap" or a "Pressure cap"?

Once the car warms up, I have water flowing slowly out of the overflow tube. The heat gauge reads OK but water continues to flow out. The cap now on it doesn't have the spring and seal on the bottom of it, so i don't think its reaching the seat.

Anyone have a Napa Auto store part number?

Thanks redron

A 1940 what?

We had a 1940 Studebaker President 8, that did not have a pressure cap. The radiator was filled, it would overflow when it warmed up. We kept the water level just above the radiator core, and it always ran cool.

If it has a flange inside of the neck, Then it takes a pressure cap, more than likely 12#. Most non pressure cars will run lower than you would think. Both my Terrap[lane 8 and my Model T puked water/antifreeze mixture out till they were happy. Neither run hot.
