Additional facts: I had a 7# radiator cap, replaced engine fan with an electric fan and shroud. I did not "burp" the system before running. The thermostat is a 180 degree and the fan is on at 195 degrees and off at 180 degrees.

I'm replacing the radiator cap with a 13# and "burping" the system by running the engine without the cap until it comes up to normal operating temp.

Question: Should I run the heater to purge it or is running it without the cap enough ? Any other suggestions ?
In addition, I would drill an 1/8" hole in the thermostat to help with purging air in the system.
