Some say, "It's a poor design if you have to put stuff in the radiator to protect head gaskets." Well, I challenge ANY of those folks to design an engine that can out-perform the 4 cylinder Subaru boxer engine.

It is an eloquent solution that has allowed the engineers to produce an amazing opened deck (and semi-opened deck) power plant that truly IS a piece of engineering art. And yes, you absolutely SHOULD be using this conditioner in those turbo engines too!) This "coolant conditioner" prevents a weep that will soon resolve itself if given the chance, from developing into a larger LEAK, requiring expensive service. (The decks on the turbos are not entirely opened, OR entirely closed. (Also worked on a fair share of Mercedes, Audi, Land Rover and Porsche at that dealership too when there was overflow)Īll I'm trying to say is that I know which end of the screwdriver I'm supposed to hold in my hand in order to use it effectively, as it was designed to be used, and am at least fairly qualified to speak to this subject with some degree of understanding.īecause (non-turbo) Subaru automobile engines have what is called an, "Opened Deck," design, head gaskets can be prone to weeping some. Automobiles ranging from K-Cars, MG A's, and Triumphs, all the way to being factory authorized by BMW. American, British and Japanese motorcycles. If it has a gasoline powered engine, two or four stroke, there is a good chance I have worked on it or something very similar. I have worked in the automotive field as a mechanic for independent shops, as well as for dealerships as a factory authorized line mechanic. If you have also warped the heads because you didn't add a bottle or two of this stuff, the machine work JUST to resurface the decks on the heads will run you about $800 on top of the rest of it. (This includes timing belt/tensioner/pulleys, and a few other sundry items that you'd be a fool if you forgo while you are this deep into the job) (Between $2,200 and $2,500 going by some 2011/2012 pricing I have) Parts alone run about $900. More than likely though, if you go without using this stuff as the FSM (Factory Service Manual) specifies, you WILL eventually be replacing head gaskets at some point. In fact, you MAY even get lucky and have no trouble at all. If you DON'T use it, you probably won't notice the difference quite as quickly as if you decided to do away with the use of let's say, MOTOR OIL, for instance. This conditioner, AND THIS CONDITIONER SPECIFICALLY, is a VERY NECESSARY PART of the preventative maintenance for your Subaru!
