    Oh Well

    works well but Subaru used to provide for free--- till your warranty ran out ! they knew there was a problem... but lied about it... soooooo you have to add this from time to time thanks Subaru.... but I'll buy another brand...

    Not sure yet

    It seems Subaru cannot get a head gasket that holds up through more than 100,000. I bought a 2009 Outback that had been pampered its whole life only to discover less than one year later that it had a head gasket weeping. I purchased this product, having used it in another Subaru, and it seems to have slowed the weeping. I know this is a good product, I just hope I caught it in time. I'll still have the gaskets replaced in the near future, I just don't want to risk coolant in the oil and a ruined motor.

    Sealed minor head gasket leak

    My 2001 Subaru Outback has 306000 miles. After changing the totally blown head gaskets I noticed a minor leak in the new head gasket that would present itself as a cold start misfire. It would misfire when the outside temperature was below zero. I was going through a cup of coolant a week, with this Cooling System Conditioner the cold start misfire is gone and the coolant leak has stopped.

    Tried it once...I don't use it.

    If your system is good, I wouldn't use it. It's a dealer stop leak product, not a conditioner, and kind of tints your coolant somewhat brownish. My head gaskets are good, so why bother with messing with something that ain't broke. This one is mild, so it won't plug your system if you do use it, but why bother then.

    Great for subaru cooling systems. Prevents leaks and repairs small leaks. Works great to prevent head gasket problems.

    207,000 + miles on my 2000 Outback

    Bought my 2000 Outback new and now have 207,000 miles on it. I usually drain, flush, replace anti-freeze once a year and always have to use this additive to prevent loss of coolant.

    Got here on time.

    The product got here right on time and was a great price. Haven't been able to see if it works to seal the head-gasket yet. Am hoping it will.

    Great price

    Bought a “bugeye” and changed out all the fluids. Used coolant additive and blue Subaru antifreeze. Works great and gives you peace of mind knowing you followed Subaru maintenance requirements. I heard good and bad things about this product but Subaru would not recommend a product if it was bad and causing problems. Buy it and protect your investment.
