Re: [Chrysler300] Radiator fan shroud

[John Lazenby <french_fryguy@xxxxxxxxx>]

1955 & 56 Chryslers without A/C use a four blade fan and the A/C version was six blades along with the square shrouding.

I have seen that on all '55 Chrysler hemi's, there is a round fan shroud
tube encircling the fan.  On a/c cars, there is an additional box around the
back of the radiator to assure fan-forced air passing over and through the
squared-off corners of the radiator.  Otherwise, the air flowing through the
corners of the radiator core would only be speed-induced and this would be
negligible in stop-n-go traffic.  Perhaps this practice continued on into
later years so that you may want to be sure to obtain the fully-boxed shroud
if that was standard on the '57 a/c cars.  I believe the number of fan
blades, water pump impeller blades and pulley ratios are different, also. 

My '55 C-300 heats up in stop-n-go traffic without the box shroud and
without a/c.

Subject: [Chrysler300] Radiator fan shroud

Hello All -

I am carefully restoring my late father's 1957 Chrysler 300C convertible
with air conditioning. I understand that only the A/C cars were equipped
with the SilentFlite over-running fan clutch and a fan shroud to improve
cooling efficiency, especially at low or stop-and-go speeds. I have found a
new thermal-actuated fan clutch as a viable alternative to the apparently
NLA SilentFlite, but for over six months I have not been able to find a fan
shroud from any of the numerous salvage yards suggested to me. I am now
resigned to having the shop in charge of the restoration fabricate one from
scratch - he's an excellent metal fabricator. However, we need a model upon
which to base this fabrication.

I understand that such a fan shroud would appear on the 1957 and 1958
Chryslers, Desotos and Imperials equipped with factory air conditioning. If
any members have such a fan shroud on their air-conditioned cars (or know of
someone else who has one), I would really appreciate it if you could send me
a few photos of it from whatever best angles you can see (left side, right
side, top view, how/where it attaches to the radiator frame, etc.) so we can
best replicate the shape of your original. And other descriptive details
would help a lot, too, such as, ".top/bottom pieces are split horizontally
and screwed together at small flanges on the sides.", etc. NOTE: that
"description" is totally made up, just for illustration of the kind of
descriptions that would really help this reconstruction.

Any help would be sincerely appreciated.
