yupp cleaning up clogged radiators and heater cores blows hardcore!!
nope, looks like its fresh clean stuff too lol but good for you, you must be a natural to know its shit anyways! green is really the only way to go. theres a few diff colors. at least yellow, orange, pink, green. make sure you have a good quality coolant! you will know the difference! weather is doesnt cool normal, or eats your radiator apart
