RE: [Chrysler300] Radiator core fins on 300D

["Gary Nelson" <gnelson@xxxxxxxxxxxx>]

Very good information. Thank you Gil.
also, does your data books list the radiator no. embossed in top of tank for
those radiators, a/c and non/ ac?

Thank you,

  Keith and All:
  I think I can shed some light on the "straight fin" vs "squiggly fin"
  radiators.
  According to the Engineering Data Books, published by Chrysler, (6/57 and
  6/58) there were four radiator vendors in 1957 and 1958: Blackstone,
  Fedders, Modine, and Long. Only the first three were ever used on the New
Yorker
  and 300s. Blackstone and Modine utilized the "Fin and Tube" design and
  Fedders used the Cellular Tubular (CT) design. (The "squiggly" type)

  For 1957: Non-A/C cars used ether Blackstone (2.5" thick, 9.5 fins/inch);
  or Fedders (2.25" thick, 12 fins/in.)
  A/C cars used only Fedders (CT type) @ 2.5" thick, 12
  fins/in.)

  For 1958: Non-A/C cars could use the Blackstone, (now 2" thick, 11.5
  fins/in) or Fedders (2" thick,12 fins/in)
  or the Modine (2" thick, 11.5 fins/in.)
  A/C cars used only Blackstone, (2.5 in. thick and 11
  fins/in.)

  IN SUMMARY (Finally!): 1957 and 1958 NON A/C could be EITHER tube and fin
  or CT
  1957 A/C would be ONLY CT
  1958 A/C would be ONLY Tube and Fin

  I can only hope the above is remotely understandable when in List Server
  form.

  I just had a beautiful re-core done on my C - not cheap at $575 - and
  replaced my very original "straight fin" one with a virtually identical
  new copper core. But then that's for 1957. In that year only one
  appears to have been used in both A/C and non-A/C cars - 1686456.

  But for '58 two different numbered radiators than the '57 are shown
  depending on whether the car came with air or not. Yours is for the
  non-air application, Maybe those other cores you saw were the 1754875
  for air cars. And maybe someone can verify whether that one had the
  squiggly fins instead of the straight ones.
