Dura Extended Life Dex-cool antifreeze / coolant meets GM 6277M-GM’s new Long Life Coolant specication ,is a single-phase ,extended life , premium ethylene glycol based antifreeze, anti-boil product which has been specially formulated with selected corrosion inhibitors to provide year-round protection of the cooling system. This product protects all metal surfaces within the cooling system including solder, copper , brass , steel, cast iron, and aluminum. The effectiveness of the coolant is improved by the anti-foam properties which works by preventing air bubbles from forming and interfering with the coolants ability to cool.
Dura Extended Life Dex-cool antifreeze / coolant is recommended for automotive and truck cooling systems and other industrial machines
Mixing ratio : 50/50 (1 part coolant to 1 part water), providing protection over a temperature range from
–37oC ( -34oF) to 150oC(302oF).
It meets the following performance requirements:
ASTM D3306, D 4985, D4340, D5345, D4656, D6210/11
SAE J1034, J1941,J814C, J1038

Ford ESE-M97B44-A / M97B18-C
Cummins 90T8-4 / 3666132.
Mercedes , BMW , Audi, Toyota , Nissan , Subaru.
S Meets GM 6277M- GM’s new Long Life Coolant specification ( DEX-COOL®)
5 year or 150,000 miles service interval
S 8,000 hours or 400,000 miles service life in heavy-duty applications not requiring nitrite.
S Constant cooling through improved heat exchange in the cooling system.
S The high alkalinity reserve protects metal parts like cylinder heads, water pumps and radiators against electrolytic corrosion.
S No effects on automotive rubber hoses, gaskets and synthetic parts.
S Clogging up of the radiator by rust particles and other types of sediment is eliminated.
S Storage stable for at least 8 years.
