Airstream Glycol Fluid by Alde | Part # 360371-301C

Keep your Airstream’s Alde heating system performing at its best with this genuine glycol fluid blend. Formulated to support efficient heat transfer and long-term system protection, this mixture is made from 50% distilled water and 50% glycol, providing the correct balance for proper circulation and freeze protection.

This fluid is designed to maintain a pH value between 7.5 and 8.5, helping prevent internal corrosion and ensuring consistent performance. When your system is cold, the fluid level should sit about 0.5" above the “minimum” line on the expansion tank for optimal operation.

For continued reliability and system health, Airstream recommends replacing the glycol every 2 years.

Warning: The heating system must be filled with a mixture of water and glycol. Use only high quality ready-mixed Propylene glycol (with inhibitor) intended for use in aluminum heating systems. The glycol must carry the label GRAS (generally recognized as safe). Alde recommends only using ALDE brand glycol specifically formulated for the Alde heating system.
