Subaru coolant???

Featured Replies

Interesting articles on endwrench, but it's always difficult to separate the marketing hype from the technical merit of the information, For example, I cite the section on brake fluid in the May06 pdf. on fluid maintenance:

 

Genuine Subaru Brake Fluid (P/N SOA868V9220) is a special DOT3

formula, designed to maintain a high boiling point even in the most

severe operation conditions. It offers superior protection against metal

corrosion, has great high temperature stability and does not form harmful

sedimentation. It meets all Subaru OEM specifications and must be used

for warranty repairs.

 

It's safe to say that all DOT3 brake fluids share the same chemical properties.

 

I've been using Havoline Extended Life (read DexCool) in my Forester for the past 60K miles without any issues. It is true that its OAT composition will react to air as noted by Porcupine and another Endwrench article, though I am inclined to think that most members of this forum keep a keen eye on their coolant level.

 

I just purchased some Peak Long Life coolant so this will be what I use the next time I replace the coolant in my Forester.

Yes, that's true. Everyone selling a product has to sell the sizzle. To check the coolant level for a soob, the radiator cap must be removed.
