coolant conditioner and headgasket material
A brief internet search shows that the coolant conditioner subaru recommends is designed to attach to he headgasket material. If I've replaced my headgasket with an MLS Felpro headgasket set, is this coolant conditioner still recommended or even useful? I had my heads resurfaced and these new MLS gaskets are not leaking as of yet, been running with water and radiator flush for a couple hours now, wondering if I need to add this stuff when refilling with proper coolant or not?
