Good to see you got it repaired trouble free and that price you can't beat! How long did those Black Onyx HG last?
Thanks! They lasted roughly 70k miles. I did the studs and black onyx back BEFORE they became a problem so I wouldn't have any issues traveling... I found out shortly after that they were failing on the Powerstroke forums. After my long trip to Lake Ontario, they had enough and started puking coolant from the bottle. So far, still good on the "new" oem ones after 3600 miles
