"Water boiling temperature increases with pressure, so a cap that won’t hold pressure can cost you dearly."
"I bought this replacement cap for our 2008 F350 6.4 diesel."
"The price on this was less than what the auto parts wanted for a aftermarket one, why pay more for a after market one when you can get a oem."
"Motorcraft quality!"
"Excellent replacement OEM part from the original I had on the coolant reservoir."
"2nd one i have bought in a year."
"Never had an issue with my old cap, however they tend to wear out so I prematurely replaced mine with this one and this cap leaked like crazy."
![Stant 10227 Radiator Cap - 13 PSI](https://images-na.ssl-images-amazon.com/images/I/41WRnxRO4jL._SS600_.jpg)
The Stant SWIV-EL radiator cap design allows the cap to be installed and removed much easier than conventional radiator caps, because the shell of the cap rotates independently from the upper sealing gasket, stem and bottom plate. A faulty radiator cap can cause your car to boil-over at a lower temperature.

"Purchased this cap with a premium radiator and in one month, my car overheated so i pulled to the side of the road."
