DENSO LLC LONG LIFE COOLANT is the all season type engine coolant which is not only to prevent freezing, but also prevent rust and corrosion and control over heat. Use the coolant with concentration of 30% above for every car inspection. (In cold region, 50% above)

The glycol represents the antifreeze element of the mix, guaranteeing that the fluid doesn't turn into ice under harsh winter conditions. On the other hand, glycol also prevents the coolant from reaching the boiling point in Death Valley heat; it keeps engine temperatures stable under all climate extremes and driving conditions. Coolant/antifreeze includes additional additives that prevent rust and corrosion in the radiator, engine and the vehicle's heater.
