Well, your water pump is right above the opti, so it could very well be that. I'd jack it up and take a look if you can. There is a weep hole on the bottom that could be the culprit.

Your thermostat could be leaking as well. I'd pull off your intake elbow and check that the thermostat is ok and that the screws are tight and everything.

haha... true true. the thermostat is good, no leaking there.. im pretty sure it was from that "weeping hole"... dang... if i filled the radiator up with fluid, it would be ok to drive a little ways to get it fixed right?

Depending on the state of your water pump, it should be ok to drive a short distance if needed, after topping off your radiator. It's never a good idea to get moisture on your opti, but if you can't help it then no point in worrying about it.

I'd still check to make sure that the water pump is leaking, if at all possible, so that you don't make an unnecessary trip or spend money you don't need to.

Very simple to replace... if you buy yourself a haynes manual and take your time... or better yet just search for a write up on this board. Since you have some basic upgrades on your car you might want to look into getting an Electric WP.

Welcome to the club

It was a huge pain for me and my friend too, trying to get to all the bolts and taking off that AIR pump thing

Rest assured that it goes much faster putting it back on since you know where everything goes.

Also make sure you get all the hoses on right

Today I had coolant spewing everywhere and causing the car to stumble (getting on optispark I guess)

Had it towed to the mechanic to see what it was...called back and said it was just a hose that was put on wrong, but the pump seemed to be installed great (that was a relief)

Said they are going to keep it till wednesday though because apparently my coolant sensor is bad and they need to check it cold.

Anyway

Just dont forget to put that sleeve on for the shafts between the timing cover and water pump

And also the job is easier if you just unbolt the fans...give you a little more room.

Good luck
