Description
Confirm the selected variation, quantity, package contents, current offer, and store terms before placing an order.
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.
No structured vehicle fitment data is available. Compare the listing with the vehicle and existing part before ordering.

Martin A. Baumhof –
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.
Bob B. –
Just what I needed to top off my Alde heating system in my RV.
Don –
Arrived on time. Topped off my Alde reservoir in my NuCamp 400.
Jackiemae –
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

Somewhat hard to find. Price is what you would expect
