Coolant leak off engine , fire wall side . Present of engine overheated . No water in oil . thanks , Ed
There are freeze plugs on the back of the head and the block too. I suggest you replace then all since they have aged the same. Replacing one at a time will only do a patch job and you'll never know when the next freeze plug will start to leak.
SOURCE: engine block freeze plugs are leaking coolant
You will have to replace the freezer plugs. Please rate this solution.

The only plug that I am aware of is at the bottom of your rad.

The back side of the cylinder head has metal fitting/pipe connected to a hose that goes to the heater system inside the cabin, the hose sometimes cracks off just behind the clamp holding it to the metal fitting/pipe.

Have someone pressure test the cooling system - you likely have a head gasket leak

open the car hood. look at the radiator, and then the top radiator hose. follow that hose to the engine. the hose connects to the thermostat housing cap. under that cap is the thermostat. here's what you need: ratchet, and sockets, flat-tip screwdriver, scraper, pliers, a new thermostat (any auto parts store), a new gasket, and some gasket sealant. Question, how old are hoses? if 3 years or old, let change those also. 2 new hose, 4 hose clamps, and some coolant. If we're changing hoses with this, lets start. drain the radiator, and remove the hard hose first, the bottom. now remove the top.hose, and lets start the thermostat. remove the bolts holding down the cap, and gently pry off the cap. flip the cap over, and scrape it clean to metal(we want NO leaks). now reach down and remove the thermostat, and lets scrape the housing clean to metal. place the new thermostat in the housing, and lets put a thin coat of gasket sealant on the housing. place the gasket on the sealant, and pick up the cap. apply a little gasket to the cap. place on top of the gasket, and bolt it down. now hook the hoses(if your changing them)and let sit 30 minutes for the gasket sealant set. after that, let add the coolant, and water. start the car, let it warm up. when the new thermostat opens, add more coolant as need to top it off. Hope this helps
