I have a Subaru Legacy Outback 1999. It has a small coolant leak and when I do a pressure test the drip is coming from a plug that requires a large alan key to open. I'm not sure what that is called or if it does leak coolant. I looked on google but all the sites I looked at had images I could not view so I wasn't sure if it was the same problem I was having.

Thank you,

MANY folks have had minor leaks stop or slow down by using the Subaru Coolant Conditioner (repackaged Holt's RadWeld)

4-6 bucks - install ONLY per directions.
