Alright, Got my motor rebuilt and somehow accidentally deleted all of my pictures of lines/wires/etc. Circled and pointed to in the pic is the only hose I cant find to connect (I know the picture shows it connected as I borrowed the pic from another post). Does anyone know what this line is (I assume tis coolant), and where it is ran from. Just to make sure, the one I am trying to point to is the one that goes stright down off the intake. Also, does anyone have a picture of the 4 vacuum lines running from the metal vacuum tubes to the two vacuum sensors mounted on top the valve cover?

This is my first post on this forum, but I am a member of TTORA, and I have been using this site for technical info for some time.

 

Welcome!

That's a coolant hose to prevent the throttle body from icing up in cold climates. IIRC, it's connected to a metal pipe bolted to the block just uder the intake manifold.

 

sorry i could not see what it was good eyes man

 

I always wondered why there was coolant running through the throttle body, never would have guessed it was because of that

 

Toyota runs coolant through idle speed control valves too. It's a safety thing. You wouldn't want your throttle freezing open.

 

or would you...

 

Its in no way a "safety" thing. Its in no way to keep your throtlebody from freezing. Its plain and simply there to provide the engine coolant temp to the I.A.C. to tell it when to open and when to close so that the engine will idle correctly no matter the engines temp. If you don't believe me leave it disconnected and see how poorly your engine idles.

 

Please show me where this IAC is on a 22R.

 

22r does not have one. the 22r intake manifold is heated... as is the 22re lower manifold to some extent.
