Complete source-backed product details
The Alde Glycol is a high-performance heat transfer fluid specifically designed for an aluminum heating system. It features superior corrosion protection however it is still recommended to replace the fluid every two years. Alde-branded glycol is recognizable by its blue-green color. It is recommended that you do not mix brands of glycol. If the glycol in your current system is a different brand or a color other than blue-green, we advise that you have the system flushed by a trained technician and refilled with Alde-branded glycol.

The product was what I ordered but the bottle was open. It was in a sealed plastic bag and I was able to pour the glycol back into the bottle.

Just what I needed to top off my Alde heating system in my RV.

Arrived on time. Topped off my Alde reservoir in my NuCamp 400.

This is the recommended glycol for changing fluid in an Alde system.
SLM-C –
Bought this to “top-off” our Alde system as needed. The price on Amazon is comparable to other sellers.
Reenie G –
I replumbed my Alde heater so this was a good time to switch out the fluid to this one as recommended. I thought the price is reasonable considering the free shipping.
Chaps –
Good product by a reputable company that is somewhat overpriced
