Took mt 2017 Wrangler in to have the tires balance . The kid that took the wheels off did a little extra . When the Jeep tire job was done he took it apon himself to check things out . He toped off the expansion tank with NAPA 50/50 antifreeze . I was billed for 1/2 Gal Antifreeze will this be a problem or not . I did not see this untill i got home and looked at the bill .
