Hi folks,
I tried to locate the coolant leak, but it is impossible - a spot of coolant under the front of the engine, a spot in the back, sometimes a spot on the right side, sometimes on the drivers side, etc.

There might be more than one problem, or the coolant is finding different paths to the ground, but I could not lcoate it.
I caved and poured in Bar's leaks for coolant. So far, no dripping after about a week.

The engine temp is still fine. I read all the positives and negatives on coolant sealer on the Internet, -it may clog up your radiator, heater core, etc, but I still figured it was worth a try compared to replacing everything trying to find the leak. I'll report back to you if I have any trouble (overheats, leaks, etc).
