cookci Posted February 21, 2007 Share Posted February 21, 2007 after changing the radiator cap ive been checking my coolant daily and it never went down. a month later i changed the coolant, after the change i again checked the levels daily for a few weeks. expansion tank was almost full and radiator was full. A month again down the line the expansion tank is full however the radiator is 500ml down in liquid and im getting a rushing sound from the heater matrix??? what does this sound like? is it possible ive had an air lock for a month and not known about it? Also why didnt the radiator refill from the expansion tank or is that because it was overfilled? please advise Quote Link to comment Share on other sites More sharing options...

merckx Posted February 25, 2007 Share Posted February 25, 2007 It does sound like an airlock. I would try and get some coolant directly into the heater hoses that go through the bulkhead into the matrix. Quote Link to comment Share on other sites More sharing options...
