The Subaru Cooling System Conditioner is a product designed to be added to the engine coolant when it is changed. It is recommended by Subaru to prevent cylinder head gasket leaks from developing or to correct existing leaks in the cooling system.
Subaru engines, particularly those with an “Opened Deck” design, can be prone to weeping head gaskets. The coolant conditioner helps prevent a weep from developing into a larger leak, which could require expensive repairs.
Opinions on the effectiveness of the Subaru Cooling System Conditioner are mixed. Some Subaru owners have reported positive experiences, mentioning that it helps prevent coolant leaks and is a great OEM product. However, there are also reports of clogged radiator passages and heater cores when the conditioner is used excessively.
It’s worth noting that Subaru started adding the coolant conditioner to their coolant systems in the early 2000s to address head gasket issues with their EJ series engines. The newer F series engines, including the FA20 in the twins, do not have the same head gasket problems.
Overall, the decision to use the Subaru Cooling System Conditioner is a personal one. It is recommended by Subaru for certain models and can potentially help prevent or correct coolant leaks. However, it’s important to follow the manufacturer’s instructions and not exceed the recommended usage to avoid potential issues with clogging .
