Hello,
I just bought a 2000 legacy L and was changing all the fluids and noticed that there is a slight external coolant leak from the head gasket. My question is, is the coolant conditioner a preventive item or will it actual plug a leak? What are the chances this may stop the drip? And if it does..does the quick fix last? I have No heating issues, oil is clean and do not see any issues with discolored coolant or being pushed in the over flow. Looks to be external only. I don't like to add this kind of but I guess it is worth a shot.
Thanks
Geo
