i read in some other threads that the yellow or green coolant is bad for the engine, that the red or orange colors are better. now. is this ture or just a myth?and why? thanks

Neither is bad for your engine. The orange coolant is Dex-Cool extended life antifreeze. It is supposed to extend the life of your cooling system, but most people end up draining and filling the coolant on a quad due to wrecks and/or other maintenance long before you'd realize the benefits. The most important thing you can do to increase the life of your cooling system is to keep contaminants out and to use ONLY distilled water to dilute the coolant. Using tap water, or even bottled water, can cause mineral deposits and impurities to build up and clog things, as well as deteriorate seals, bearings, etc. Hope this helps!!
