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

I'm guessing the old cap on my 2004 Mustang was original OEM when it was brand new, so when it started to overheat a little I decided to check a few simple things first. Well after the car cooled down I took the cover off and checked it out. the spring in it no longer springs. When this new cap arrived I compared the new one to my old one and it confirmed to me that the old one just needed to be replaced. 2 months after replacement and several hundred kilometers of driving and no overheating problems with the new cover.
