Stant Radiator Cap, Black (10233)

Fit the expansion tank of of 08 Nissan Xterra. I had an issue where a small amount of coolant would evaporate and found it was due to my factory expansion tank cap losing some of its spring over the years. Factory cap is set to 14psi, when the cap doesn't hold pressure like its supposed to the boiling point for the coolant drops and you'll lose some due to evaporation. This new Stant cap is rated at 16 so its a good mild upgrade. Fixed my issue and Stant is a well known quality brand.This will only fit the expansion tank. If you need the actual radiator cap you need a different one without a spring that is rated for 42 psi. The Gates brand product number for that part is 31561, another well known quality brand.

It fits perfectly on my new radiator that I ordered from Amazon, but I did notice it was a little over $12.00 so it was more expensive than a radiator cap should be.

Ordered for my denso radiator. Direct fit no leaks.

The one I got did not have the pounds on it. Unlike the one pictured mind is blank but has 11 in the middle of the cap. I going to keep the one I took off and some antifreeze in the car just in case it is 11 pound cap and not 16 pound cap. I don't like getting something different than the one shown. But it did fit.

Works like it should seems to be good quality .

The media could not be loaded. Fits well, no leaks, priced well, engine runs cooler, cap performs perfectly when doing a pressure test.

Just got this in the mail. It’s the exact same radiator cap as the motoRad that 4$ cheaper. MotoRad logo and all. No Stant logo.
