In my experience (with 617s) burping is critical to coolant flow. In the old days. I jacked the front end to get the air out. When I got smarter, I learned that you can disconnect the top radiator hose at the radiator, fill the system through that hose, then reconnect the hose. Using that procedure, I didn't need to burp.
