What is the benefit of a 1.3 bar radiator cap?

A 1.3 bar radiator cap increases the pressure in your cooling system. This raises the boiling point of your coolant, which helps prevent overheating, especially in demanding driving conditions or warmer weather.

Does this radiator cap come with any hardware?

This product is a direct replacement radiator cap and does not typically include additional hardware. It is designed to fit into the existing radiator neck.

How do I know if this cap will fit my Subaru?

While this cap is popular for many Subaru models, it's important to verify the specific pressure rating and neck size required for your vehicle. Always check your owner's manual or consult manufacturer fitment data to ensure compatibility.

Product Details

This GrimmSpeed radiator cap is a well-built replacement that raises your coolant's boiling point. It's designed to hold 1.3 bar of pressure, which is higher than the stock cap on many Subaru models. By increasing the pressure in your cooling system, you effectively raise the boiling point of the coolant, helping to prevent overheating, especially under demanding conditions.

The black finish gives it a clean look under the hood. It's a straightforward part to swap out, making it an easy way to get a little extra security for your engine's cooling system. If you're pushing your Subaru a bit harder or just want the peace of mind that comes with a slightly more robust cooling system, this cap is a solid option.
