CSF Radiator Cap - 16 psi/Stant 10233 Box of 20

This CSF radiator cap is built to the Stant 10233 specification, meaning it's designed to hold 16 psi of pressure. A radiator cap is a pretty simple part, but it's crucial for keeping your cooling system working right. It doesn't just seal the system; it actually controls the pressure. By maintaining a specific pressure, it raises the boiling point of your coolant, which helps prevent overheating, especially when you're working your engine hard or in hot weather.

You get a box of 20 of these caps, making them a solid option if you're a shop that does a lot of cooling system work or if you want to keep spares on hand. They are well-built and designed to fit correctly, ensuring a good seal. Having the right pressure rating is important; too low and you risk boiling over, too high and you could put unnecessary stress on your radiator and hoses.
