I have read;
Type I = Green
Type II (Factory fill) = Green
Type II (off the shelf) = Blue
I have a couple jugs of Type II, but haven't opened them yet so I don't know if it is blue or green.
My factory fill is blue.

any worries when driving with the coolant level right at or a fraction below the min line? I was about 1/3 above the min line, then I installed my FIPK and some coolant squirted out when removing the coolant lines, now its maybe 1mm below the min, and of course, 1/2 - 3/4 inch above the line when the car is hot. I need to flush and replace the coolant anyway, but I don't want to make a point to do it before the weekend. maybe I'll just add a cup of water.

In case some people don't understand how the coolant tank works and why it's there:
Fluid level in the overflow reservoir should be between "min" and "max" when engine is cold. As the engine heats up, expansion pushes fluid into the tank (overflow). If it starts out too much above the "max" line, coolant could overfill the tank and be lost. As the engine cools down, the fluid is sucked back into the radiator. If it starts out below the "min" line, all the fluid could be pulled in and then air will be pulled in after that. Note that the "pick up" for the coolant tank is at the bottom.
If you are driving (at operating temp) with the fluid below the "min" line, you could risk sucking air into the system when the engine cools down.

You have a MY2000 car. To reiterate, this was the only model year that required you to flush and change the coolant at 3 years, then every 2 years thereafter. If you haven't done this yet, you are about 3 years late.
