antifreeze?
 

Any good sources for Antifreeze-Coolant Propylene Glycol
Seems harder and harder to find.
Should I just use everyday antifreeze? Or does that really corrode the bearings?

Re: antifreeze?
 

Walmart has the Propylene Glycol (the green stuff). Well at least for now. It may be totally outlawed in the future depending on who will be running things.

Re: antifreeze?
 

I bought some at our closest Walmart a few weeks ago.

QMDV,

I live in Massachusetts, and that post resonates a little too close to home. Went to the local Wally's a few months ago, and was shocked to pay $20.00 for two gallons of antifreeze. State DEP put a new tax on it. Thanks Granny Warren!

Re: antifreeze?
 

A little off topic but, does antifreeze have a shelf life? I have a couple of gallons that have been sitting on shelf for several years.

$20 for TWO gallons is CHEAP ! ! Be Happy :) !

the sierra antifreez sells for 25 dollars a gallon.

Re: antifreeze?
 

I dont believe it has a shelf life but you can always test it before you use to make sure.

Re: antifreeze?
 

Yep , I sure would be !! Now , back to the OP 's question ...Will the yellow -ish stuff be ok , or do we need the green stuff in our flatty's ? - F F

Unless it's the 50/50 in which case you are buying water.

Re: antifreeze?
 

In a 1933 model B or a 1933 v8 engine are 5 gallons proper coolant fill? or should 4.5 gallons be used because over overfill/runnoff?

Re: antifreeze?
 

Here it is $10.89 a gallon concentrated so 50-50 mix makes it $5.45 a gallon usable.

Re: antifreeze?
 

antifreeze actually does have a shelf life...sorta, in the big trucks they test it with some paper strips of some sort because it will get corrosive after 5 years or so. not sure if its from all the heating and cooling cycles, or a real shelf life.

Re: antifreeze?
 

They have so many kinds on the shelf I'm about ready to go back to alcohol. 4 cars in garage, 3 of them Fords and 4 different requirements for antifreeze. Then you go to buy some and they sell gallons of "works in everything".

It is a bit confusing with how many colours of anti freeze there are now. Besides the old green, I have some red, some yellow. Some recommended for diesel engines. On light duty gas engines I've been using "recycled" anti freeze that I have changed out of my diesel engines. Left to settle and filtered several times it looks pretty good and still tests food for our severe cold winters.

Re: antifreeze?
 

just an aside the strips mentioned can be purchased at a swimming pool supply store.they are used to check pool PH works for anti freeze as well

Re: antifreeze?
 

I bought a gal. from NAPA this summer,cost around $25/00

Re: antifreeze?
 

Regarding shelf life, I'm not sure about the anti corrosion properties but I recently drained the antifreeze out of a boat engine that was winterized 20 years ago. It was clean, still bright green and tested at -50F.

Re: antifreeze?
 

I was at Wal-Mart today and found both Zerez and the house brand. They had a lot for sale. 9.88 a gallon (not he 50/50 mix)


The 50/50 was 7.88 a gallon - mighty expensive water.

Re: antifreeze?
 

The original green permanent antifreeze is actually a ethylene glycol.

Propylene glycol is the non poisonous stuff commonly tinted pink and used as RV plumbing antifreeze.

Propylene glycol can also be used as an engine coolant. Some racing engines are running 100 percent undiluted propylene glycol. When used in its pure form, it is highly refined and not a Walmart offering.

Re: antifreeze?
 

So what PH value works best in a cooling system?

Re: antifreeze?
 

The only concern I have had regarding shelf life is silicate drop out, I have seen chunks of silicate settle to the bottom of plastic containers, if in a cooling system I use a volt meter to test for acidity normally caused over a period of time by dissimilar metals in the cooling system. I always try and use low silicate antifreeze such as peek , we had problems with waterpump seals failing in our diesel engines and the Engine manufacture attributed it to silicate drop out. if left untested/untreated for months there are risks of galvanic action caused by dissimilar metals .

Re: antifreeze?
 

Will the 'red' antifreeze work?

Re: antifreeze?
 

I would think anything close to 7, which is neutral (distilled water).
