Questions: I have a '48 sedan delivery wagon, side mount radiator. Inside of neck is 1" deep, and approximately 1 5/8" diameter. Is this part number 648360 the correct cap?
Question By: Michael Moore on May 3 2020 6:37 PM
Yes, it should be the correct one. Thanks

No, it will not seal the inner opening surface if the inside of the neck is 1". . The cap will only seal if the distance is 3/4. Also, a 4 lb cap is recommended.
