yes they take 50/50 antifreeze, make sure you oil the filter, look some where on the side of the case where you put the oil in, near the fill hole it will probally say how much oil to put in.(it won't be in ounces). i don't know if you know so no oofense, but clean the filter in kerosene(not gas) and then after that try to get the filter as dry as you can by"wqringing" it out. DON'T TWST OR CURL IT UP, IT MAY TEAR!! let it sit until it is completely dry, then apply a good filter oil. make sure the coolent is high enough so that it is level with the highest fins on the radiator. :cool:
