Arctic Forester Mike

37,000 miles. Last Radiator fluid change was in November. The I added, about 1 fourth (1/4) of a gallon of Shell's universal antifreeze, yellow in color.

Hi, I need some advice. I bought a 2010 Forester (excellent condition, 60,000km) in Toronto, drove it to Montreal to put it on a boat to ship up to Nunavut, Canada. Here's the thing, I thought the blue radiator light meant low coolant so I added ~1L ShellZone Premixed Extended Life Coolant. The label said it's safe for ATSM D3306 & JIS K2234 coolant systems. I later learend that the light was an engine warming light. I also learned that Subarus are very particular about antifreeze coolants so do I need to do a flush? I live in a remote community with a local garage whose radiator flush pump works on every vehicle. Should I let it be? Drain the rad and add the Subaru Long Life Super Coolant? I need some advice. Thanks.
