Do you have to remove thermostat to flush coolant?
Remove the thermostat to ensure we get the proper flow through the entire engine and heater core. If the thermostat were left in it would most likely be closed and would not allow fluid to flush through it.
Can flushing a radiator cause problems?
Can a radiator flush cause problems? Yes and no. Yes, because a radiator flush is going to flush out any corrosion, debris, rust, and other contaminants. If the flush isn't thoroughly to clear all of that out, it can loosen up those things which could clog up the cooling system, including the radiator.

What happens if there is air in the coolant system?
When you have air in your coolant system, it causes steam pockets in the line which act almost like plugs preventing the coolant from continuing to flow. That's why you end up with your engine overheating, because the coolant isn't allowed to continue through or it moves very slowly.
