Leaking coolant after fixing oil pressure unit

[fastestdsm]

So today I was driving and I check engine light, so I pull over and check to see that the filter was loose and oil was leaking. SO I bring the car to my friends shop and it seems like the stud that holds the oil filter was loose so the round unit that houses the filter was leaking as well. I took the filter out and tightened the stud (luckily the stud wasnt busted, or else I wouldve have to have removed the whole engine to get that fixed). SO i tightened and it was fine without leaks.

After getting off the lift, I stll wanted to make sure no leaks, so I drive the car up to 4-5 rpms reading the stock oil pressure gauge carefully, it goes up to 3/4 line before it didnt even go to half when revved that high. Everything was good with the oil, but now I have coolant leaking from the water pump area, it seems like its coming from the seals, but Im not sure. I couldnt get a chance to raise the car again but surely I look at the front driver side tire and the gap towards the front bumper and the tire to see it leaking slowly but surely from the water pump location.
SCan anyone help me out? I hope I explained this well, this is the best I can explain it so any thoughts, suggestions, etc wil be greatly apreciated..

so I found a picture, this is where it was leaking oil as I noticed, I lost about a quart. I tightened the nut where the filter screws onto, and it seems to have fixed the problem, then after fixing that I drove around to find that coolant was leaking in the same area. Im getting really frustrated with these puddled problems, someone ### buy my dsm.

The unit the oil filter screws onto is the engine oil cooler - not the water pump. It has 2 water hoses going to it for cooling one of which you have colored in your pic. Check to see if they have come loose (put another clamp on and check hose for breaks). Or the oil cooler may be damaged and leaking coolant. Or your water pump may really be leaking and dripping down to the oil cooler (water pump has a large pulley one of your accessary belts runs). If can't find leak, have cooling system pressure tested and leak will squirt out.
