Review on Stant 10228 Automotive Accessories by Juan Anderson

If you need a radiator cap that will reduce the chance of leaks and hose ruptures on older cars this will fit my radiator. Happy with it. If your cooler uses a larger cap and has a cap on top of the cooler (rather than a remodeled bottle) this will likely fit. It doesn't match the small style that many import models use. However, be aware that 7psi lowers the boiling point of the coolant, which can be an issue if you're running above 225 degrees, which I avoid when possible. I even managed to fit a modified 0psi cap but that's a bad idea as on some cars the water pump creates a vacuum on the radiator hoses which can rupture them while driving and restrict coolant flow. This cap is 7 psi on a square inch ensures that doesn't happen.
