Losing coolant while parked longer han overnight?!

[95gstnj]

Hey, the car is a s13 with an sr20det. the car feels great, pulls strong. if i drive it daily, and park it overnight, it is fine with no cooland loss. As soon as i park it for a few days, there will be a puddle of coolant underneath, dripping down on the passenger side of the engine bay right where the extra clutch bleed box and fuel lines go to the back of the car, where the transmission tunnel starts. I've been looking for leaks in that area, but i can't find any. it just seems very weird to me that it would be fine overnight, but after a few days of sitting, it leaks. if i leave it there for a week, it's a huge puddle! anyone have a similar problem?

check under the weeper hole on the water pump. Either that or if you got an s13 sr, I'd check under the intake manifold where there are more coolant lines.
