im trying to get my work done, was running my inverter and whoops...coolant started coming out of the lower hole of a thingamajiggy on the left side of my throttle body.

Appears to be connecting the heater hoses.

Anybody know what this is?

Can I replace/bypass it? Im stuck but i have tools and coolant

That's coolant running through the throttle body. You can bypass that.

thanks. yeah i bypassed that with a length of hose, i’m interested in finding out what that apparatus does; i cant find it in my haynes manual

I can't tell exactly where the coolant was leaking from.

The throttle body has coolant running through it to warm it so ice doesn't form inside, locking the throttle open, under VERY rare weather conditions.

It would be a LOT easier to help you if we could see ALL your truck's details in your signature as this caption explains:

Based on the super-rare PFEGR system, MAF intake tubes, R134a, and VMV, I'm guessing it's a '94. The heater supply nipple appears to be for a 5.0L.

Thanks for the info Steve, I didn’t know my emissions system was that rare. I feel better knowing what it is that i bypassed. the two indentations on the side of the throttle body look like caps of some sort and one of them was cracked.

There are quite a few components under the hood that are pretty rusty and i wonder if im about to start getting nicklendimed to death.

I cant see my own sig on my phone but i thought i had it all there. It’s a 96 5.0.

No, it's not showing. Follow the "your signature" link above, and put it all in there. Then check your Options to make sure "show signature automatically with each post" is checked.

If it was a bore plug that cracked, you can just extract it, clean the bore with sandpaper (etc.) and fill it with JB weld, if you want to UNbypass the throttle heater.

Everything will work better & last longer if you keep it clean:
