Last night after filling it up with coolant I let it run for a 1hr and me and the guy I bought it from searched and searched but could'nt find a drop of leaking coolant. I put a big sheet under it last night and not a drop this morning. I drive it to work right afterwards this morning probably 25 minutes away and park it. I noticed coolant leaking from somewhere on the left side up near the radiater but its not visuable because the car is grounded. What is the pump on the left side up near the radiater?

After work I checked coolant levels in the radiater and it lossed alittle. The overflow went from full to low but still visable. I topped it off and drove home where it'll leak some when I stop. It seems to leak only when I park it after driving it.

C'mon techs help me out...

I'm gonna try to get my jack back from a friend today.
