I have the waterfall sound in the dash area, I do not have any other indication of a BHG...no over heating, no coolant loss no milky oil cap and I just changed the oil and no coolant that I noticed...That being said I was wondering if instead of burping the cooling system could I just flush and refill the system...I noticed there is a connection for a hose on the coolant lines closest to the dash...how do I go about flushing the system..thanks...Oh on a side note I think I have air in the system becasue I changed the Rad and did not refill it properly. Any input would be great...thanks all...
