    I have 2009 freightliner Columbia that is building up air pressure in the antifreeze tank, The tank is brand new as is the egr cooler , there some black substance appearing in the tank , I have to add antifreeze everyday but check engine light still turns on after driving for a while . There is no antifreeze leaking from anywhere , what can be the problem?

    Do this ...

    Go and get the coolant system flushed and change the radiator cap.

    What motor? If oil is in coolant the 2 prime suspects are head gasket or oil cooler. Oil pressure is greater than coolant pressure so oil in coolant is the first sign.
