1 In the replacement of antifreeze before you use the water, because there is water rust in the tank, the water rust has corroded the tank, just there is rust in the will not find leaks! Then add antifreeze, antifreeze has a rust removal function, he will be the water rust and reaction off, that will have been corroded in those places will be due to the absence of water rust blockage and leakage phenomenon!
2 The antifreeze you use when the counterfeit antifreeze! The main ingredient of formal antifreeze is ethylene glycol! The main ingredient of regular antifreeze is ethylene glycol, which is slippery to the touch and does not seep when dripped on a concrete floor! The taste is slightly sweet! Counterfeit antifreeze has a variety of one is made of industrial salt, the freezing point is relatively high, that is, easy to freeze, at the same time more corrosive, especially aluminum tanks and cylinders performance is more obvious! Feel no slippery feeling, slightly salty taste, there is a fake is blended with industrial alcohol, this antifreeze corrosive relatively small freezing point is low enough! Is the boiling point is too low! At about 80 degrees will open the pot! Feel no obvious slippery feeling, slightly sweet taste, but the hot state of alcohol flavor is very strong! Very easy to distinguish!
That's mainly it! Your problem may be caused by using counterfeit antifreeze! You can go to the place of purchase and get a claim from him!
