Update:
Just did the Coolant flush today. Took off the plastic belly pan under the radiator, cleaned it with soap and water, followed by plastic dressing to give it that shiny "greasy" look. Probably will only look clean for a week since it's under the car lol. Anyway, poored the Subaru Anitfreeze and Coolant Conditioner into a container followed by doubling it's amount via water (the back of the antifreeze container said to mix it 50/50 with water). Before I dumped it all in, I turned the heater on full blast while dumping water through the radiator with all plugs loose to "flush" the whole system out as per Subaru's instructions. Dumped it all in and had a decent amount left over. Since the Coolant Conditioner was less than $2 I'm going to buy another container of it and dump it all in.
Also have my first mod coming in the mail
