Radiator Cap

Posted by Chris R On 2021/3/11 20:34:00

Hello all,

I'm going through the cooling system on my 53 300 (327 4bbl), and I'm trying to replace the radiator cap.

The factory service manual states that the 2631 chassis series came with a 12 lb cap.

I noticed that the Super Clipper (327 2bbl), and the regular Clipper (288 2bbl) both came with a 6 lb cap.

It looks as though all the 327 4bbl cars got the 12 lb cap.

I noticed on Max Merritt's site, that one cap is listed for all 53-54 cars.

Obviously, this is a little confusing.

What cap do you guys suggest I run? Or, does it not really matter?

Thank you,

-Chris
