SUBARU Cooling System Conditioner photos SOA635071 and SOA345001

Here is my collection of SUBARU cooling system conditioner bottles.  I like to keep a few spare bottles on hand for when that urge to change out the SUBARU coolant hits.  Plus with SUBARU bucks the price for a case isn't very much anyway.  I like to use a bottle and a half in the SUBARU engines prone to the external head gasket leak, such as my 2000 Outback Wagon with the 2.5L DOHC phase II.
