Whats this metal tube?

It is not connected to either of the rubber hoses. Just kind of looks like it.
No guessing please. Only answer if you know what it is.

 

Looks to be for the coolant hose.

 

yea looks like it should go to your throttle body coolant hose that comes from the water pump. are you dripping coolant somewhere??

 

throtle coolant hose

 

Isn't there some sort of mod where you remove that hose in order to keep the throttle body cooler? I remember reading that its only there to defrost the TB under very cold conditions.

 

OK Thats right I remember now. It is a coolant hose. It was removed to keep the throttle body cooler. I guess they run hot water there to heat the charge for better combustion? Dunno But Thanks guys. For the life of me I could not remember. LOL

 

Are you guys sure? It looks like its connected to top of the TB. Looks more like a vacume hose.

 

Typically they run coolant through it to keep it from icing over.
