Frequently Asked Questions
Q: What is the pressure rating of this radiator cap?
A: This cap features a 1.8 bar pressure rating to help raise the boiling point of your coolant.
Q: Does this cap replace a stock factory cap?
A: Yes, it is designed to directly replace the OEM radiator cap.
Expert Pro-Tip: Never remove a radiator cap when the engine is hot. The cooling system is under high pressure, and boiling coolant can cause severe burns. Always let the machine cool down completely before checking coolant levels or swapping caps.
