OK everyone, I know this topic has been covered some, but I'd like some more info or opinions. I changed out the water pump on my 07 and decided to change the coolant while I was into it. Went to the dealership to get the HOAT coolant as listed in the owners manual. I told them want I wanted and why. The parts woman showed me the OAT on the label, and said that's what I needed. Mechanic sitting nearby confirmed. It was like the HOAT was not important. So I get home and it's purple not pink. It's 10 yr. 150,000 mi vs 5yr. 100,000 mi. Should I use it or get he HOAT. Your thoughts. Thanks
Sort of my thinking, that's why I wanted to check with some folks on here. I didn't do a total flush just what came out when I removed the water pump, and then I poured about a gallon of distilled water through the radiator. Raised the left side to get more out.
