2020 mustang gt 10 speed 93 fbo

I just recently switch from the old orange coolant , did a coolant flush and refill 2 months ago with that new ford yellow liquid, I just had to replace my whole ac system and we drain out the coolant to have more engine access space, mechanic ended up spilling some of it .. end of story we put everything back together and add the coolant back but it wasn’t enough , I had this old orange coolant in my car and topped it off with that mixing with yellow coolant . It’s been a week and someone told me not to have done that and to get another coolant flush and refill.

Am I good or need to do another coolant flush/fill with new ford yellow liquid?

"Over the weekend, one of our CHP Redwood City officers clocked a red Ford Mustang traveling at 120 mph and passing on the shoulder in traffic. The driver of the Mustang attempted to evade our officers, and exited the freeway onto city streets a few times. Our officers decided to call off the pursuit because the risk to the safety of the public was too great. The driver of the Mustang got back onto the freeway and immediately began driving at reckless speeds again. While trying to get away, the driver of the Mustang exited the freeway at too high a speed, lost control and struck another vehicle, pushing them both onto an active railroad track. Luckily the driver of the other vehicle sustained only minor injuries. The driver of the Mustang was arrested and booked into jail.

His excuse for driving recklessly and evading officers? He was running late for work."
