Re: [FWDLK] Cooling w/alcohol

["Jason Rogers" <jasonr@xxxxxxx>]

I'd never heard this prior to this posting.  So I pulled out my '55-'56
Plymouth Service Manual.  In it, a 160 t-stat is clearly specified for the
Powerflow 6, and a 155 is specified for the V8.   These are "start to open"
temps.  The "fully open" temps are 195 for the 6, and 185 for the V8.  This
manual doesn't specify a t-stat vs. coolant application.

Then section V.3 discusses anti-freeze solutions: "...the system should be
protected with a reputable brand compounded from denatured alcohol, methanol
(synthetic wood alcohol) or ethylene glycol...an alcohol type anti-freeze
solution is subject to evaporation...Do not use a high temperature
thermostat (180 deg. F) with an alcohol-base anti-freeze solution."

Regarding Nick's debate over which t-stat to use in his '56
6-cylinder....I've used a 160 t-stat (and 50/50 ethylene glycol) in my '55
6-cylinder and never had any problems with cooling performance.

You learn something new every day....

Hi 'Lookers,
     About the 160 thermostat... I recently read in an old Motors manual
that 160 stats tended to be for cars running alcohol based coolant, while
cars running glycol based coolant were recomended to go with 180 stats.
Various car's stat charts had different listings based on the coolant used.
I have no idea if this is relevant to the recent posts, but I am curious to
see what feedback this tidbit generates.
