Small Coolant Leak

[Verybadwizard]

I replaced my radiator about 10k miles ago and I have small leak I'm not sure where its coming from. It looks like the leak happened a while ago and I haven't lost any more fluid since I first noticed it a few weeks back. Coolant is up to the radiator cap. The coolant level seems to be just a bit below high and low marks when engine is hot and cold. So I probably lost like a cup to 1/2 cup of coolant in 10k miles? It all seems to have leaked around the MAF. Or it over pressurized at some point and the cap sprayed coolant? What could be causing this any suggestions would be greatly appreciated. Thank You!

I'd say that first you'll need to clean up your engine bay from old coolant residue, and keep an eye on new coolant leaks. There's crust around your throttle body plugs, that hose looks bad, but can't guess, need to diagnose in situ.

Check this thread about the plugs:

This is a strange one. 2003 LC. Our second LC. 135K miles. Drove our 2000 to 288K miles. I am not as clueless as I'm going to sound! Do a lot of my own work; it's in great shape. Wife's DD. Two nights ago in the driving rain, my wife calls me to tell me that there is steam pouring out from...

My small coolant leak was a worn out thermostat gasket between the two pieces of the thermostat housing
and a little seepage at the hose connected to the outer thermostat housing. The coolant can get whipped
around by the rotating belt/fan and land anywhere up there.

If you have pink crust around that hose junction it may be time for a new coolant hose and if there's pink
crust in between the two pieces of the t-stat housing, you may as well just replace the t-stat and gasket.
