Review on Enhanced Ford 9C3Z-8101-B Radiator Cap with Pressure Relief - Genuine OEM Part by Dave Cavazos

Revainrating 5 out of 5

Just what you need

There are a few fakes. After some research, I would highly recommend OEM. I've learned that non-OEMs may not have the correct PSI rating. Without the proper PSI cap, your antifreeze will boil off, especially if you have more than a 50/50 high water content water mix. If you don't want to lose head gaskets or antifreeze I would highly recommend this cap.
