For small amounts of air on a system with an overflow bottle, yes.
Problem is large amounts of air from partially draining the block
or pulling the heater core can cause an airlock in some motors and
the overflow system only works for a small amount of coolant at a
time. It's faster and safer to top off the radiator then run the
engine a few seconds to burp out the air.

Re: Burping a radiator?
No.
Some of the hoses run up high and can get air locked. Especially the
long run heater hose on the CJ7s.
