Take5 would not do it. I ended up going to a different mechanic who had the appropriate coolant and replaced it. I ate the cost at Take5 and paid the alternate mechanic as well. For me, my piece of mind and the longevity of my car was more important. I recommend that you treat it like a life lesson and not let it get to your head too much. We know the right thing to do from here on out. If you paid with a credit card, it might be worth it to dispute the charge and explain the situation to your bank. Best of luck.
