Dusty said:The color of antifreeze is no indication of the type of antifreeze that is installed. Here is a technical bulletin from the Filter Manufacturers Council that explains the different types of antifreeze and other details about the product. Possibly it is more information than the average person would want, but it will take less than 5 minutes to read it and it will give you a new perspective on antifreeze types.

My poor Gruman body Freightliner with a ISB 5.9 Cummins feels left out, it's color isn't listed in that article. It has purple antifreeze.
I was unfortunate enough to be working at a International truck dealer when over the road tractors started switching from good old green antifreeze to the newer extended life antifreeze. What a disaster that was. First orange, then pink, then yellow, then blue... Drivers adding the wrong coolant when they needed a top off, others adding DCA to coolant that did not need it, others that did not add the needed extender additive at the scheduled intervals to extended life coolants. Then you had companies like CAT that realized the early silicate free coolants were causing water pump failures and had us add a silicate additive to the collant to update it. Just a big debacle. Numerous water pump failures, coolant gelling from mixtures of incompatible collants and cylinder liner cavitation leaks. I wish they would just bring back the good old day's of green antifreeze, test at every service interval with a DCA test strip and add DCA as needed.
