MotoRad is the only thermostat manufacturer that produces true "High Flow" thermostats for today's higher performance engines. The wider opening allows up to 50% more coolant flow. This causes a reduction in engine warm up times, allows trapped air in the cooling system to escape, and stabilizes the pressure of the cooling system overall.

• Made of stainless steel with enlarged openings to provide increased flow
• Triple-bridge design increases strength, stability and reliability
• Jiggle valve removes air pockets
• Bypass valve allows a small amount of coolant to circulate before fully opening.

Which Thermostat Is Right For You?

What Temperature Thermostat Do I Need?

Thermostats have a “rated” temperature (such as 180F or 195F). This is the temperature the thermostat will start to open, releasing heated coolant from the engine into the radiator. The thermostat will fully open once the coolant gets another ten or fifteen degrees warmer.

Cooling System Maintenance | Tips & Tools

Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:

• Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
• Consider replacing the Radiator Hoses (and Hose Clamps) and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
• Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
