![]() ![]() In a pinch run anything you can find to keep it full if you have to get it hime.ĭONT pick your coolant by colour, you have to read the label to make sure you get the one you want. The new universal coolants use unique OAT-based corrosion packages with proprietary organic acids (such as carboxylate) to provide broad. Dex-Cool and other 'Universal' orange and green coolants are not to be mixed either, as. Makers of universal coolants say their products are formulated to be compatible with all cooling systems (foreign or domestic) and all coolant types (traditional green, OAT and OAT-hybrid with silicate). While I advocate only running OAT (and I personally recommend Nulons stuff) If you have a potentially compromised cooling system (if youve run green coolant to ease up leaks its compromised) then get HOAT coolant. Ford specifically states in their manuals and maintenance guides that Motorcraft Premium Gold coolant is not to be mixed with any other type of coolant, including their own Premium Orange and Premium Extended Life Green coolants. Heres the kicker back in the day it was simple you had green coolant and you had red coolant now you have every bloody colour under the sun picking coolant by colour is like going into bunnings to the paint colour chart and asking for "blue" umpty million shades later and youve come home with the wrong one.

OAT antifreeze had been widely used in Europe before its introduction in North America. Organic Acid Technology (OAT) was the first LLC / extended life coolant introduced in North America in 1994. Replacing the coolant on your 2011 add either Green to Green or Gold to Yellow, or cross. Thats the exceptionally simple version there are other differences. The normal IAT service life is two years or 30,000 miles (50,000 km). Mixing of engine coolants may harm your engines cooling system. The red stuff has a lower surface tension and is also more compatible with dis similar metals so your high nobility cast iron block will not sacrafice your lower nobility aluminum radiator or your oil cooler via the coolant as readily. The old school green coolant is "thicker" than the red stuff. ![]()
