What is Freezetone coolant additive? - PeachParts Mercedes-Benz Forum

Supposedly, this company has been here in Florida since 1978.
Freezetone Products Inc.

Never heard of them but it's available at ALL the Adv. Auto stores in my area for $2 for a Gallon.

Says use instead of water. Sounds better than just distilled water for corrosion but has kinda a low boiling point. I can't seem to find much info on this stuff other than a few reviews from AA.

Usually for questions like that you can google' MSDS and the name of the product....

It looks like some sort of third-world knockoff of something else, including the name.

Freezetone Products Inc.

It's formulated for "combustible engines". Unless your engine is made of magnesium, I don't think it fits that category.

I only found an MSDS for the additive:

http://www.aapmsds.com/msdsimages/m8/sds/f/freezetone%20products/900.pdf

It's just sodium nitrite (in water), which is good for corrosion protection in steel liners (good for diesels), but offers no other protection, and no freeze protection.

Glycols are a bigger corrosion risk than water. They gradually degrade into acidic byproducts in the presence of heat and air, which is why coolant needs to be changed from time to time. Antifreeze contains buffering additives to handle that, in addition to corrosion inhibitors to handle other sources of corrosion.

I wouldn't bother with it. But feel free to be the first on your block to try it.

Genuine Mercedes coolant $26/gal at the dealer, distilled water 89 cents at the supermarket. Change it every 5 years. That's what, just over five bucks per year? Easy.

But if you have the time to conduct an experiment with an unknown product, and you don't mind risking your car in the name of science, go for it.

I'm going to flush my system with the prestone stuff and then change it out several times after that on short intervals.
There is some orange film left from dexcool a long time ago but I changed to G05. The engine cools well so I don't want to do a CitricAcid flush.

At 2 bucks a gallon.... better than just water, but not a permanent thing. I normally run the zerex and distilled.

I do have another problem. Slow coolant loss. Haven't been able to figure it out. I just add a little water every few weeks to top off the reservoir. Not much, but I eventually dillute my antifreeze with more distilled water than it should be. Is the block drain bolt ever the culprit of a slow leak?

Save an old coolant jug, and pour 1/2 of a new one into it. Fill both jugs the remainder of the way with distilled water. You now have two gallons of perfect 50/50 mix to use for top-ups.

Yea, that will be the thing to do.
Thanks for the responses.

I guess I'm still surprised no one has heard of that stuff... since 1978 and STILL nobody uses it. How the f#ck are these guys still in business?

Slow coolant loss could be a pinhole leak anywhere in the coolant system.
Typically loose hose clamps, old or damaged hoses, corrosion and pitting of hose nipples, water pump going out, cracks in coolant recovery tank, bad pressure cap on coolant recovery tank,
and even a head gasket breach that allows a connection between a coolant passages and a combustion chamber.

Closely inspect all of your hoses for damage and clamps for tightness.
Look for any coolant drips under the car, or signs of dried coolant on or around the radiator and coolant recovery tank.
Check that the rubber seal on the coolant recovery cap is still pliable enought to make a good seal.
Pressure test your coolant recovery cap.
Check for any coolant smell coming out of the tailpipe or in the cabin when you run the heater.

If you still can't find the leak(s), maybe invest in a UV detection like this one from Home Depot.

Just browsed that Freezetone web site, good grief it's bad. Typos everywhere. Bizarre "engrish" phrases like "Our company mission is to educate every consumer that water should not be used in your cooling system. Water is a limited resource that should be used exclusively in our daily lives". Our daily lives? What? Every automaker in the world uses water in the cooling system, but freezetone knows best!! yeah... right. And "for more information get in touch with salesman." Do they only have one man?
