Hopefully, its not a precursor to the topic at discussion in this thread?
So, it's done. Passenger side is definitely cold now after last coolant change. I think the Holt's (subaru coolant conditioner) is definitely a factor. I shouldn't have bothered adding it in.
I've now drained and refilled the system twice in an attempt to get rid of any remaining coolant mixture and refilled again with just Peak extended life coolant and distilled water.
I'm going to get the heater core flushed next week at the dealer in an attempt to restore flow.
