Coolant System cummins isx

[Sanat123]

Did any one had this problem ? all hose that connects to the radiator is pumping, and loosing anti freeze coolant from the top of the reservoir antifreeze tank. Loosing about 6-7 gallons of antifreeze coolant each week. I've replaced the air compressor, after two weeks the problem was still there. After that I've replaced the thermostat and new reservoir antifreeze tank. After all the the replacements the problem did not go away! if anyone had the same issue and know what may caused the problem i would really appreciate your advice.
