Hello. I have an 07 impala LT engine 3.5 V6. So I did the coolant flush I followed a video. But I'm not sure if I used the right coolant.... I recently bought the car and when I saw the coolant container thing reservoir I think it's called it was literally empty I couldn't tell what color it was.... I didn't know i could check from radiator ( I know now after doing the flush) so the one I put in is AutoZone extended life antifreeze and coolant 50/50 dex- cool compatible do not add water. Can someone please let me know if it's the right one? It's orange color.
