with the blue subaru OEM super coolant:RS- Good morning! I looked in the reservoir last night, and I think the coolant looks blue (the so called 100k coolant?). I have to suck a little out to be sure. With only 65k on the odo, maybe I can wait on the coolant job until next spring. We could get 10" of snow any day now so I'm trying to wrap all of the car projects.
"The color of this coolant is blue and the first replacement interval is 11 years/220,000Km (137,500 miles).
The second replacement interval after that is 6 years/120,000KM (75,000 miles). "
as per
Subaru maintenance schedules and new car break-in period- 2000 through 2009, links for 2010, 2011...
and if swapping make sure to use a OEM stat and new OEM rad cap. (every other day there is a post here about aftermarket stats, and aftermarket rad caps,....the OEM cap measures in KPA, and like all aftermarket ones measure in PSI).
