Hey guys

I check my engine bay quite a lot, i've been meaning to flush the coolant out of my car (not because it's bad but because i want to ) and mines green. I heard you're suppose to use orange? I've been using green Prestone for years and years and the car runs super well. The Temp gauge doesn't go over 100C ever. it sticks around 80c in the summer and in the middle of that in the winter.


What do you guys think?

Thanks!
