The overflow problem is caused by the in-correct positioning of the over flow tube.

My radiator was overflowing 50 years ago and since I followed the service bulletin it has not lost any water since then ...even when driving at 65 MPH for several hours.

The 1930 service bulletin for fixing the overflow problem is on Page 450 of the Service Bulletins.

This bulletin stops the overflow and makes the roofing nail un-necessary.

You can use the nail at your own risk but if the radiator ever boils over the radiator can be split open or the tubes may split ... where ever the weakest place is in your radiator.

Additional info:

See post #8

When the pressure gets high enough the nail is held down by the pressure and then the nail stops "Dancing" and no steam can escape and the radiator quickly bursts.

I predict that some one will use the nail and post asking why their radiator has burst.
