Replacing alcohol in Alde system.

jdargis

Per the Alde manual, the alcohol is to be replaced every second season, to maintain the anti-corrosiveness of the system. Has anyone done this themselves, or took to a qualified Alde dealer?

On reading the other Alde App, if you are using Alde alcohol, it can last up to five years without changing it.  If you use somebody else's alcohol, they recommend changing every two years.  So the big question, whose alcohol is in our systems?

I believe this s what the factory uses: http://www.peakauto.com/products/antifreeze-coolants/automotive/sierra/

Which brings up the question of what time frame do we use to change the alcohol in the system, 2 yrs, 3 yrs ?

It's a glycol mixture, similar to auto antifreeze. In fact, Alde in Europe uses VW G12++, which is good for 5 years. With that said, stateside factory fill is good for 5 years, and its a more safe type.

Thanks for the info, one less maintenance not having to do for a few more years.

And it can be bought at.....Tractor Supply.  Does anyone know of any other place to buy ETOH for the T@B?

You can go to the Sierra Peak website and plug in your zip. In my area, it's Advanced Auto and Dollar General.

SgtJohn - ETOH?

ETOH is a medical term for alcohol.  Sorry.

Thanks Pix!  I went to peak auto.com and they have a gallon of propylene antifreeze but it is harmful to acetate pipes and I don't think we have acetate in our T@Bs.  Also, I'm not sure how much propylene the Alde holds but... I can always drain the system and measure the amount or drain the system and fill it to the appropriate level on the plastic bottle in the rear panel.  I'll figure it out, it isn't difficult.  Thanks again, I don't have to drive 20 miles, the propylene is nearby!
