coolant leak from firewall? pics

[19964Runner]

my coolant level has been dropping lately, even after i top it off. today i noticed some water or coolant puddle under the car. open the hood and see some leaking from a small round thing on the firewall on the passenger side. does anyone have any idea what that it? pic below

That's the drain for the A/C condenser and it's supposed to drip water. You're loosing coolant somewhere else. You might want to do a cooling system pressure check.

There is a freeze out plug on the back of the engine (top and center) that can have a tendency to leak. Mine is weeping a little.

thanks, i'll go inspect it soon. how hard is it to replace this plug on our engine?

Check your coolant lines underneath the passenger side running to the rear heater. They rust out very easy because they are in direct line with the front passenger side tire. If thats the case, cut off the old lines and get some rubber radiator hoses and hose clamps

Ever find your problem? I'm still chasing mine, had pressure checks, block checks replaced water pump/tstat etc. Still can't find mine I'll check the freeze plug next, may just replace it anyways.
