Review on 🔧 Motorcraft Radiator Cap Assembly (Part Number RS527), Black by Tay Tran

This is a genuine Ford product, hence it has five stars in that sense. Only three stars though because in my experience it only lasts a few years before needing to be replaced. This is my third radiator cap. If I could find a good after-sales service option, I would go this route. I bought this for my 2006 6.0 diesel and it fits. Too bad Ford doesn't make a better product. However, they are relatively inexpensive. As soon as I notice that I have to add fluid too often or I smell coolant, it's time to replace it. FOLLOW-UP: It took less than a year.
