Re: RC 15 Radiator Cap Real or Fake
GM / AC Delco produced that part number radiator cap for how many years, and in how many countries, and had how many suppliers manufacturing them? Until that question can be answered, I doubt that anyone will be able to answer for sure if that is actually a genuine RC15. Now, if you were to ask if that one is correct for a certain year of car produced in a specific plant, that would be a lot easier question to answer.
For instance, I have had AC spark plugs that were manufactured in England that looked a lot different than the same part number manufactured in the good old USA. Good luck with your search for the answer.
The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.
