High Pressure Radiator Cap with Thermometer | 0.9–1.3 Bar
High Pressure Radiator Cap with Thermometer | 0.9–1.3 Bar
High Pressure Radiator Cap with Built-In Thermometer
Upgrade your motorcycle or powersports cooling system with this durable high-pressure radiator cap. Crafted from robust aluminum alloy and silicone, it is compatible with Honda, Yamaha, Kawasaki, Suzuki, and Polaris models. Available in three pressure ratings — 0.9, 1.1, and 1.3 Bar — this cap delivers a higher pressure rating than standard OEM caps, helping to raise the coolant's boiling point and minimize coolant loss during demanding rides.
The standout feature is the integrated thermometer on top of the cap, giving you an at-a-glance reading of your engine's operating temperature — ranging from 0–200°C / 32–400°F — without any additional tools or gauges. Perfect for both 2-stroke and 4-stroke engines.
Made in Mainland China.

Frequently Asked Questions
Q: What pressure ratings are available for this radiator cap?
A: This high-pressure radiator cap is available in three pressure ratings: 0.9 Bar, 1.1 Bar, and 1.3 Bar. Each option exceeds standard OEM cap specifications to help maintain optimal coolant system pressure and reduce coolant boiling or loss during heavy use.
Q: Which motorcycles and powersports vehicles is this radiator cap compatible with?
A: This radiator cap is designed to be compatible with a wide range of Honda, Yamaha, Kawasaki, Suzuki, and Polaris models on both 2-stroke and 4-stroke engines. Always verify the fitment against your vehicle's specific radiator neck size and required pressure rating before purchasing.
Q: How does the built-in thermometer work on this radiator cap?
A: The thermometer is integrated directly into the top of the radiator cap. It provides a continuous temperature reading ranging from 0–200°C (32–400°F), allowing you to monitor your engine's coolant temperature at a glance without needing separate gauges or sensors.
Q: Will this cap increase the boiling point of my coolant?
A: Yes. By operating at a higher pressure than a standard OEM cap, this radiator cap effectively raises the boiling point of the coolant. This helps keep the coolant in liquid form longer under high-performance conditions, reducing evaporation and coolant loss.
