I have the waterfall sound. Don't think is a BHG

[ebang]

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...

Sounds like air in the system, try burping it.

1) Park on a hill or up on ramps.
2) Remove the radiator cap **Perform this sytem burp IMMEDIATELY after a cold start**
3) Give the engine a few revs and look for air bubbles being purged from the system.

I curently don't have parking brakes, that is why I was wondering if I could just flush and refill

You could but more than likely you will let even MORE air in. Just have a buddy shove some blocks behind your wheels and send it up on ramps.

I've heard that before but never tried it. So try both, lol.
