Just finished up a head gasket job on my 2006 Subaru Outback. It's had lots of years of the official Subaru "coolant conditioner" (aka Holts Radweld). I noticed a decent amount of gunk inside the coolant jacket and head that I'd like to flush out, now that the car is back together.
Any recommendations?
A youtube video recommend Irontite ThoroFlush for cleaning out stop leak. The MSDS lists sodium carbonate as an active ingredient, and I believe TSP has been used too.
