They go to your coolant lines. You should have two similar lines coming off your coolant system and they need to be connected to it. I've heard of some bypassing them, but I'm not sure to what advantage.

They can leak and cause all kinds of cool problems that will haunt you for months. Especially the one that goes back behind the engine.

The purpose of those lines is to prevent the throttle body from icing over in colder weather. Advantage of bypassing is so that you have cooler air coming through versus the air warming up as it passes a hot throttle body.
I have had cars where the tubes got clogged and the only solution was to bypass. Never had an issue with doing that/any issues with the throttle body icing over.

Coolant is running through the Tbody for initial Idle speed control. As the coolant gets to operating temperature your ISC/FIAV in the Tbody will send the signal to the ECU adjust idle. When you start your car cold idle will be very high till it reaches operating temp and it will idle normal.
You can bypass it it will just take longer for your vehicle to idle normal especially in colder climate and in some cases it will idle rough until warmed up. Bypassing it wont cause any long term damage...just for those in colder climate you may have to press on the gas pedal to help aid the motor "warm up".

... As the coolant gets to operating temperature your ISC/FIAV in the Tbody will send the signal to the ECU adjust idle. .... That is incorrect. The IAC doesn't send anything to tell anything to adjust idle. The ECM/PCM uses ECT to judge coolant temp which THEN sends the appropriate signal to the IAC to adjust idle. The IAC is Idle Air Control (or Idle Speed Control) - and that is ALL it does. Edward |
