So, I called out the owner on the DexCool issue as well as the hoses. He said that he'll swap out the hoses when ever I want (no problem). Then he told me that they used the "prestone gm dex cool anti freeze." I said, "but last night you told me that you just put in dexcool. I'm confused." He said, "that was my mistake last night sorry, this morning i looked at the container . the top says gmdexcool approved."
For all I know, he could be lying just to appease me. I wish there were a way to tell the truth.
