Throttle Body Coolant Bypass (with pics), Want to bypass the coolant flow to your Throttle Body on you 5SFE? Options

[Spider77]

So, after quite a few PM's on how to do this I finally broke down and took some pics. You will notice however that I did not put everything back to "factory settings", ie, I just took a few pictures and hope that they'll help the ones who want to know how to do this.
First off though, a warning:
****THE COOLANT WILL BE HOT AFTER RUNNING THE ENGINE, THEREFORE TO AVOID BURNS I STRONGLY SUGGEST THAT YOU LET THE ENGINE/COOLANT SYSTEM COOL DOWN BEFORE ATTEMPTING TO DO THIS, I AM IN NO WAY RESPONSIBLE FOR PERSONAL HARM THAT MAY BE CAUSED WHILE ATTEMPTING THIS, YOU HAVE BEEN WARNED****

STEPS:
1:) You want to start by disconnecting your SRI/CAI/Stock Intake at the throttle body:

2:) Disconnect the 4 Vac lines (three on top, one that sits lower):

3:) Disconnect the Throttle Cables (one for Man, two for Auto):

4:) Remove TB by pulling the 4 12 mm bolts:

5:) Remove TB from Intake Plenum:

6:) You will notice three lines hooked into the TB, two outside line (coolant) and one middle line (vac). You want to "bypass" the TB by linking the two coolant lines together, using a 5/16th brass bard (male to male) fitting and screw clamps to tighten it down. Please do not use existing hardware as its probably been sitting there for a while and chances are it wont stand up. Please use new hardware (screw clamps).




7: After you insert brass barb (male to male fitting) and tighten down the screw clamps, you might want to install some vac caps on the coolant ports. Although I cant say if its required, for me its just piece of mind):

8: Reattach the Vac line (its the middle port)!

8.5: Totally optional, but at this time I did a minor cleaning of the TB, and the butterfly valve. Not required, but while its open, might as well, right?
9: Check your work. This is what you should have, two coolant lines "looped" together, two coolant ports capped (optional), and the Vac line (the middle port) reattached. Make sure that your screw clamps are tight (either use a socket or the right size four point to make sure its super tight...don't want leaks), and again, check another time. Once you are sure everything is done, place your throttle body back on the intake plenum, place the SRI/CAI/Stock Intake back on, and enjoy!

While I can not say this is how it is for different engines, the concept is the same. So, for all those people PM'ing me, this is how you do it (again ,mind you its not a pure step by step, but you'll get the idea), and for those who want to know how to TB Bypass on the 5SFE, here you go!
I hope this can help answer this question to some extent. If anyone sees anything wrong with this (ie mislabeling please let me know so I can correct).
Thanks and hope you enjoy!

It's there to prevent icing of the throttle plate and IAC under certain driving conditions, like high humidity and medium to lower ambient temps. The pressure drop across a small opening like the throttle plate can cause the air to be cold enough to condense the water out and freeze it. Ice in your throttle is bad, in the IAC it stops it from being able to idle the car right or at all. Typically the heat conducted through the metal intake manifold would be enough, but if you've just started driving and the intake manifold is cold there's a potential for icing. The hottest coolant available is routed for the throttle, so it warms up fast and prevents icing. The amount of surface area in the throttle body, the speed at which air passes through, and the time which it has to absorb heat through contact (not to mention the insulating effects of the boundary layer) mean that very very very little heat is gained there. You'll pick up more heat from the intake manifold and cylinder head port than the throttle body I would think. It's one of those 'I did this thing and spent time on it and it cost me nothing so yes it definitely did something', though I really doubt it does.

Do it, don't do it, odds are there's no gain and very little chance you'll ice the throttle body. Just remember though, auto makers are the ultimate penny pinchers and they always heat the throttle body, they must have some reason.
