Water Wetter question

[yellow_cad]

On the Water Wetter bottle, it recommends to use at

least 15% anti-freeze in street cars. I have a 1950s car used for shows and a

little driving all in California so I'm never concerned with winter

temperatures. I really don't understand why the 15% recommendation. Seems like I

would do better to use straight water and Water Wetter since occasionly my car

gets a little warm (long steep grade) and this is what I am trying to prevent.

Probably for anti corrosion properties........Bob

But the bottle also states that "Water Wetter provides excellent corrosion protection."

Anti-freeze is not just for cold, it also could be called "anti-overheat" too.

Absolutely NOT true. See attached quotes from "The Engineering Toolbox":

"Note! The specific heat capacity of ethylene glycol based water solutions are less than the

specific heat capacity of clean water. For a heat transfer system with ethylene

glycol the circulated volume must be increased compared to a system with

clean water.

In a 50% solution with operational temperatures above

36 ^oF the specific heat capacity is decreased with

approximately 20%. The reduced heat capacity must be compensated by

circulating more fluid"

and

"Increase in Flow required for a 50%

Ethylene Glycol Solution

Increase in circulated flow for 50% ethylene

glycol solutions compared with clean water are indicated in the table below

I got hold of Redline tech and they said, 15% anti-freeze is only needed if you might experience freezing temps or if you have air conditioning. I don't quite understand the air conditioning but they say ww is sufficient lube with water preferably distilled water.

after seeing the effects of 90+ years of corrosion in the aluminum water manifold of my '22 Mercer, I am converting to Evans coolant to eliminate water completely. Electrolytic properties of water over the decades contributed to massive amounts of material loss, I would guess 4-5% of the AL. It looks like rotten wood. The AL water pump impeller was as porous as a sponge.

Can't remember what it is called, but I have one dangling in my radiator to be the bait for corrosion. It can be done to a larger scale when you have lots of aluminum. Jim

Hi! All

I'm new on this forum and am still reading with interest. I live in Ill. bout 35 So. of Chi town. I have to use anti freeze but I don't use Etel, type Glycol rather use Polyproplyn Type. The reason being is it mixes with the water if for some strange reason the water gets into the oil it dosent wipe out the bearings, I had this happen a few times on a 47 Ford V/8 Flatty I had in a 47 pickup driven at 45mph with a 4:11 banjo rear end, just some food for thought.
