what is this?
I was looking at the engine running yesterday and found a little hole with coolant in it so I tried to clean it with a cloth and found it is about 1.5" deep and threaded. Is it supposed to be a bolt in here?
Thank You.

leak
you sure the heater hose isnt leaking? when cold i test using pressure on the system, to reveal leaks not traceable when hot, metal contracts causing "mysterious" leaks

I checked the hose but no I don't it is that. The only thing there is the t-stat maybe the seal could be leaking but I don't see how coolant could get there.

Anymore ideas? I still don't know what this is. Oil and coolant are clean (not mixed) it isn't loosing any coolant either but I just can't leave it alone until I find out what it is.

It looks like either a mount for an accessory or a bolt to hook a chain to if you need to lift the engine. As for the coolant, I;d check the clamp on that hose by it.

it's not a mounting point for a hook used to lifted the engine or the head. the eye-bracket that's between the thermostat housing and the head is what you use to lift the engine and/or head. i'm betting the heater hose is split and you just can't see it. with the tight turn that it makes, the vibrations from the engine and the constant contraction and expansion from heating cycles, over time it will spring a leak. replace it and go from there.

Clean out the hole, poke in a piece of cotton-ball, and watch it to see how soon it becomes soaked with coolant.
It probably will take months.
I wouldn't worry about it.
Whenever this thirty-day monsoon abates, I will look at several of mine to see if there is anything bolted into that hole.
