Subaru Coolants

Are you looking for the right coolant for your Subaru? Then you’ve probably noticed that it’s not as easy as with many European car manufacturers. That’s because the original Subaru coolant isn’t easily available to end consumers. But are there high-quality alternatives? We’ll tell you!

The Original Subaru Coolant

Just like BMW, VW, or Opel, Subaru also relies on its own coolants. The so-called “Subaru Super Coolant,” available in green or blue, has been consistently recommended for all Subaru models for many years. These Super Coolants usually come as a ready-to-use 50/50 mixture, offering protection for the cooling system down to -34°C.

However, availability of the original Subaru coolant in this region is quite limited. Even on marketplaces like Amazon or eBay, original products are hard to find. In such cases, your options are visiting a Subaru dealer or specialist workshop—or choosing a suitable alternative.

Subaru Alternative: Glysantin G30

The German coolant manufacturer Glysantin is well-known for its compact yet versatile range of products. For Subaru models from model year 1977 onwards, Glysantin G30 is the suitable coolant. While it is not directly recommended by Subaru, Glysantin has decades of experience in producing high-quality coolants. Glysantin G30 is not green or blue like the original, but purple. The major advantage of this alternative is its wide availability—most well-stocked online shops and marketplaces carry Glysantin coolants, both as concentrate and as ready-mix solutions.
