Coolant leak
I am having a small leakage of green coolant. By small, I mean fairly slow, its not spewing out. However, I cant seem to find the location for the leak. I am going to go to autozone and get the radiator pressure gauge/pump to see how fast the pressure drops. Any ideas on how to find the leakage spot and what else could potentially be?
Thanks

What vehicle/motor do you have? Is this your 318 Duster?

First thing I'd look at would be the water pump and see if its seeping out of the bottom behind the pulley.

After that look at the thermostat housing, intake manifold at the heads, radiator hoses and radiator and heater core and hoses. It is possible that the heads are cracked and you might see water leaking from the castings or you have a head gasket issue. But this is a start on places to check for water. If it's the water pump you will need to replace it and it's not a bad job at all. If radiator or heater core cooling system sealer can work hoses need replacement.
Intake manifold gaskets leak over time as do thermostat gaskets so you will need to replace them at some point especially if a previous owner with little experience had gotten into the motor for any reason.
Good luck with your search

If you can't find a leak try a bottle of Copper seal in the radiator, Copper or Silver.

Yep rusty freezplugs can get you and can be a pain to fix in the car.
