Hi All
I am new to this , but need solve some mystery , let me start my Vogue 3.6 v 8 Diesel start develop loosing coolant once a week little top up nothing to worry about no visual leeks under the car ,month later I noticed some white foam coming from expansion tank , got new cap , did not change enything ,I did check oil cap for any indication of coolant or rise oil level surprised nothing strange as usual.My money on hedgasket gone but did the chemical test on operating temperature and another surprise liquid blue as new but trough the test without pumping the tester the pressure was bubbling trough liquid with out changing colour .Now coolat losing trough expansion tank as white foam , no power loss or overheating , few days ago I noticed driver side blowing cool air and pasanger side hot next day top up coolant opposite reaction .Did any one had similar problems, as if it is hedgasket and I miss something please advice (some people said air gets to the system and gets coolant boiled but where to start ?)
