While checking the coolant in my 2004 Camry that I just bought , I see that the coolant is kind of an opaque red as opposed to the more transparent red I have in my Corolla is something wrong that made it opaque or is it just a different brand or is there an additive in there? Or is oil somehow getting into the coolant what do you think? I include pictures of each of the coolant inside the radiators. Thank you very much I'm quite worried about this. The last picture is the more transparent coolant in my Corolla
