Worth a freebee shot.
My car actually has a second radiator type cap incorporated into the intake casting at the designated high-spot that makes burping the system very easy. I looked in our manual and didn't see anything specified as far as any designated "high spots" in our cooling system though.

All the manual really says for our systems is that re-filling the system at a slow rate once any work is completed is the best way to prevent air pockets from forming.
