Gates 90-93 Acura Integra / 90-97 Mazda MX-5 Miata / 03-06 Nissan 350Z Radiator Cap - 13 psi

This Gates radiator cap is built to hold 13 psi, which is a common pressure rating for many vehicles. The cap is a critical part of your cooling system; it doesn't just seal the radiator, it also controls the pressure at which the coolant operates. When the coolant heats up, it expands and needs a place to go. The radiator cap allows the system to build pressure, which raises the boiling point of the coolant, helping to prevent overheating. If your cap isn't holding pressure, you might notice your engine running hotter than it should, especially under load.

Gates uses a well-built spring and seal design to ensure this cap functions correctly and lasts. It's designed to fit a wide variety of vehicles, including popular models like the 1990-1993 Acura Integra, 1990-1997 Mazda MX-5 Miata, and 2003-2006 Nissan 350Z, among many others. Replacing a faulty radiator cap is a simple and inexpensive way to help keep your engine running at its ideal temperature.
