Enviro HD Coolant Premix
DUO PRODUCTS ENVIRO HD COOLANT PREMIX is a superior, fully formulated, nitrite-organic acid technology (OAT), ready to use propylene glycol based engine coolant. It is more robust than both conventional and organic acid technology (OAT) engine coolants. DUO Products Enviro HD Coolant Premix is recommended for use in automotive, light duty and heavy-duty diesel applications such as on-road truck, off-road mining, farm and marine where an environmentally acceptable coolant is required. It provides protection for up to 4 years, 6000 hours or 500,000 km.
DUO PRODUCTS ENVIRO HD COOLANT PREMIX contains no silicates, phosphates or amines whilst utilising one of the most advanced corrosion inhibitor packages available on the market.
Whilst Duo Products Enviro HD Coolant Premix is compatible with most propylene glycol based coolants, it is good practice to drain out the used coolant, flush the system to remove remaining used coolant and deposits, then refill the system with the new coolant mixture.
Duo Products Enviro HD Coolant Premix should be added to the cooling system as is.
PERFORMANCE STANDARDS
Duo Products Enviro HD Coolant Premix meets many common performance standards for OEM vehicles manufactured after the year 2000.
