Dose anyone know or could check their cap and let me know what lb. size it is for a 55 324 thanks.

 

hey ive got a 7lb cap on my 56 324..................john

 

Thats what I have but it dose not seem to be holding.

 

Hi doc93
my 55 has a 7 on it , it looked abit rusty so i orded a new one from fusicks that was a 7 , so i would say your one is stuffed if its not holding pressure.
cheers chris.

 

Doc 93, Mine is a 7lb also. When I replaced my raditor it had a 14lb cap on it and the shop owner commemented that if I wanted my radiator to live I should replace it with the correct 7lb cap, seems the old system won't take the extra pressure for an extened time.
You might need a recoar or other issues may be the problem, perhaps the T stat is shot....Tedd

 

I just put a new stat in it a couple of weeks ago ( which there was none )and I will try a new cap and see if that works. I just wanted to make sure that was the right size and that for the info too.

 

Located a new cap and put it on so far so good. Thanks for the info guys.

 

Just had to recore my 57 radiator... 7 lb cap.. puked until some of the real high water was expended, 100 degrees in Dallas.

 

What did the charged you for a recore?

 

doc.93.... $450... brass core.. Happy to find someone to fit core to OEM tank and supports. I think it ended up a 3 row...... still holds a great deal of water.
