Did you bleed the air out of the system?

... and we are all assuming you changed the radiator cap? Also assuming you got a proper mix of water in the system.
Systems don't run well on higher proportions of coolant/water. Water is what transfers the heat more efficiently.

Are you sure it is actually overheating and not getting a false reading from the gauge. If it is a real overheat problem it could be that your engine block is partially blocked and may need to be flushed.

Glycol is a desicant. It attracts water, used alot in dehydrating natural gas, that is the reason use a mix of water/coolant.
