I have a 2019 Subaru Outback 2.5i 108k miles
I've been busy with work and was about 2,000 miles overdue for an oil change, so I went to Farm & Fleet to get one. Thursday afternoon, I did a longer drive than normal, about 55 miles. I needed to add some washer fluid, so when I finished driving, I opened the hood and found my coolant extremely full. The liquid in the coolant reservoir was blue, whereas before it was universal green, as a body shop put in universal green when I hit a deer about 8 months ago. My washer fluid was empty, so I believe they added washer fluid to the coolant reservoir. When I called, they said they only fill washer fluid. They said I could come in, and after checking the cameras, they did see that someone filled it with washer fluid. As it is still separated from coolant and washer fluid, they are taking out the reservoir, emptying it all out, rinsing it, and then filling it with the correct coolant. They also drained the radiator and put in Peak Asian blue coolant. Do I need to worry about it mixing with the universal green?
If I remember correctly I had green P-HOAT coolant in there and the shop filled with Blue POAT, is that still good?
Scotty does not usually return to topics he has already answered.
If concerned, simply flush out the cooling system to get rid of what's in there and replace it with the coolant that Subaru specifies for that vehicle.

Now. I understand you're busy. But going to a chain shop is not the best thing for your car- your story is sadly far too common with chain shops. Try and locate an independent mechanic in your area as these types of mistakes are far less likely to occur there
No, you don't have anything to worry about. Windshield fluid is just alcohol and water. It wouldn't really hurt it anyways as long as only a small amount

HI, Scotty, they added so much, that they filled the overflow reservoir almost to the top with washer fluid, so way pasted the full mark. The green coolant at the bottom of the reservoir, seemed to have not mixed with the blue washer fluid as I was able to the see separated colors. If I remember correctly I had green P-HOAT coolant in there and the shop filled with Blue POAT, is that still good?
