You probably won't see any adverse effects temp wise, however it will have an adverse effect on the thermal properties of your water. If you really put a lot in you will see it won't "thin out" and change to green or bright blue like it should, rather it will stay in some part in the color it is in the tube. I wouldn't worry about it, but if you are then drain your system and get more distilled H20 and dilute it. I'm sure you know but for future reference you need literally one or 2 drops for an average system.
