Coolant leak coming from intake manifold

[willfill]

I noticed my car was leaking quite a bit of coolant today, looked under the hood and it appears to be coming from either a hose, or a gasket in the part that the hose attaches to, on the intake manifold.

I'd like to replace both the gasket and the hose, as I'm not sure which is the problem, and if I'm going to drain my coolant I think I may as well do both of them. So I just need some help identifying the part numbers that I'll need. I have a video that I'll post too in case that helps at all, but I'm pretty sure it is either the hose or the gasket.

The hose I circled in the 2nd photo is directly under the piece with the arrows pointing to it in the 1st photo.

I'll edit the post w/ the video when it's done uploading.

You should really check the pressed in vacuum fittings on the opposite side of the Throttle Body. They tend to get loose and cause drivability problems from the air leak. My adivce to you is to take the TB off and thoroughly clean everything and remove corrosion with scotchbrite. Reinstall the air fittings with JB weld and let it cure inside over night (especially in Canada).

Having the TB off also allows you to replace that gasket and makes the whole job easier since you dont have to bend over the car while you get everything meticulously clean. :p

This 100% ^...and I would just add that removing the TB allows you to add the drain hole in centre of the TPS cover so oil doesn't accumulate in there and foul the switch.

Correct. But epoxy the fittings back in with the throttle body installed and hoses connected so the angle of the nipple will be correct.
