Re: [Chrysler300] Water Temp and engine bay heat issues

[<smopar@xxxxxxxxxxxxxx>]

I second Dan's comment.  In virtually every issue involving an RB engine (413, 440, etc) running hot, it boils (no pun intended) down to fin spacing of the radiator core.  By now, most cores have been replaced, but most replacement cores out there have low fin density (its all about making money of course), i.e., relatively few fins per inch.  I replaced one of my radiator cores with a new "heavy duty" Modine 4 row, only to have worse heating problems than a plugged up original radiator.  After talking to a good radiator shop, they told me to just go to a 3 row and specify a high efficiency core, and heating issues should go away.  They replaced my core with a high efficiency Craig core and problems went away.
