RE: [Chrysler300] living with modern anti-freeze products

I agree with the recommendation to exclude air from our cooling systems.
Perhaps the new corrosion inhibitor packages have oxygen scavengers that can
only gobble up a small amount of O2 and will poop out if fresh air is
ingested each time the engine heats up and cools.

Below is information on a 7# radiator cap that is supposed to work on
'51-'56 Chryslers with overflow bottles.  I'm trying to find one and may
have to modify the overflow tube on the radiator of our '55 C-300 in order
to route it to a milk jug or somesuch.  Although, I don't see any problem
with tying a rubber tube onto the bottom end of the existing overflow tube
and routing it to the "milk jug".  Anyone successfully done this on a
'55-'56?

More demerits.

We enjoyed the Chrysler 300 Club, Inc. meet held last week in Tacoma.
Minimal precipitation early morning before the show, then dry all day.
Forward Looking to Branson.

Hoping no members are suffering from the horrible wildfires in this state.
We drove through two smoky areas on I-5 on the way home from Tacoma.

Subject: [Chrysler300] living with modern anti-freeze products

Ok, after this subject has been beat to death several times, and after a lot
of 
reading, both reports, and manufacturing claims, and taking into account
direct 
experiences, I think I have figured out the main thing we need to so for our

vintage cars surviving this sort of modern automotive chemistry.

OVERFLOW tanks, of any sort that allows an overflow radiator cap AND fluid 
maintained in the tank. THE reason seems to be that NO air is to be in the 
cooling system at all. I think all current formulations being sold today are
of 
this nature. The only way to do this is to purge as much air out of the
cooling 
system and to maintain the same mix in the overflow tank. As the final bit
of 
air gets purged by the normal operation of the system then the fluid that is

used will not break down as fast in the cooling system. The particulates
that 
settle out and develop the crud that blocks the heater core and other small 
passages then does not happen (normally), sometimes as fast as 6 - 12
months. 
This short time span breakdown I have personally seen and experienced in
systems 
comparable to the 55 - 65 cooling system designs.

I think the first signs of the breakdown can be seen in the overflow tanks
as a 
film of buildup of the particulates as they settle out of the fluids exposed
to 
air in the overflow tank.

All one should have to do for the 2 or so years between changes is to make
sure 
that the overflow container never runs dry during the periods that you
operate 
your car.

I personally will still adhere to the 2 year change out cycle, regardless of
the 
vintage automobile. We have seen the desirability of doing this even with
modern 
cars.

AND above all else, Do Not Mix Types of coolant in the same system.
