coolant is always best. I would get rid of the green coolant, flush it all out and replace with something better. I use Peak Final Charge in everything.
Pros: always best, better performance

I have some Peak "original equipment technology" for European vehicles, "violet." It is pre-diluted. It seemed to immediately blend right in, if that means anything.
Pros: blended right in

They want $25.98 for six gallons of Peak brand washer fluid at Sam's Club! I remember paying half that only five years ago.
Cons: expensive washer fluid
I paid for a coolant flush and the mechanic put back in peak 50/50. The orange kind not the gold. At least its not mixing with the HOAT but im pissed
Cons: Wrong type of coolant
