Motul MoCool Radiator Coolant Additive - 500ml

Experience cooler, more efficient engine operation with Motul MoCool, a high-performance radiator coolant additive specially developed for use in racing and high-temperature driving conditions. Whether you're on the track or dealing with engine overheating in everyday use, MoCool helps reduce coolant temperatures by up to 15°C (30°F), improving heat transfer and overall thermal efficiency.

MoCool is ideal for motorcycles, cars, quads, and ATVs—particularly in environments where factory cooling systems struggle under extreme loads. It’s especially effective in racing applications, with approvals from ASRA, CCS, and WERA, making it a trusted choice for competitive riders and drivers alike.

MoCool is a concentrated formula designed to be mixed with distilled water before use. It contains powerful anti-corrosion agents that remain effective over time, helping to protect your cooling system’s water pump and metal surfaces without harming non-metal parts. Unlike traditional coolants, MoCool is not intended for antifreeze protection but rather for maximum cooling performance.

If you're looking to reduce engine heat and improve cooling system efficiency, Motul MoCool is the perfect solution. Whether you're racing at full throttle or just trying to avoid overheating in summer traffic, MoCool gives your engine the cooling edge it needs.

ATTENTION: Some racing regulation do not allow anything else than pure water, if any doubt, check with race official organisation before using MoCool. Motul Company cannot be involved in case of race disqualification while using MoCool inappropriately. 

MoCool does not provide any antifreeze protection.
