Plan to install my AEM CAI this weekend. I was hoping that the instructions would show how to bypass the coolant line connected to the throttle body. But, it does not BYPASS it. The instruction show to make connections to allow hot water to flow thru the throttle bady.

CAN I RE-ROUTE THE HOSES TO *NOT* ALLOW HOT WATER TO FLOW THRU THE THROTTLE BODY ?

I live is Houston, so I am not worried about the throttle freezing open. I would like to keep the intake plenium as cool as possible.

I may have found the answer to my question. I did a search, and found this thread -

It is really easy as well. I installed the AEM one for TLS-Fiend a couple weeks back and bypassed it using the factory hose. Once I disconnected the hoses from the TB, and removed one of them, I jumped the remaining one back to the coolent system.

Good luck with it. Jason

Got it done. Here is a pic.

The green line is highlighting the hose routing where it loops back.



And here is the overall pic.

did you plug the hole on the bottom of the TB at all?

i plugged mine, but honestly don't think it matters. i took apart my throttle body, and the area the coolant flows through is a tiny pocket. from what i can tell the coolant does not even flow through the whole body, but mainly just the IAC sensor/TP sensor.

I did not plug the TB hose fittings because I want it to dry-out. At a later time, I might plug them. But like CleanCL said, it is not neccessary to plug them to prevent any sorta leaking.

Black_05_TL_6SP,

By the way, your post did help !!!!!! I did not realize that I could just jump it until you mentioned it. So, that is how I did it. THANKS Black_05_TL_6SP !!!!

Can someone help me understand why you are doing this?

Is it part of the CAI install or a seperate mod you are performing at the same time?

^ Supposingly this mod would make the throttle body a bid cooler cause it eliminates the hot coolant flow through it, resulting in cooler= denser air = more power. The Injen CAI install does not mention this mod, only disrupted hose reconnect. However, the Outlaw spacers install use this mod and call it a racing mod, meaning not recommended in freezing temps.

I didn't know you could eliminate one of the coolant hoses and redirect the flow into one hose, apparentely you can, good info!

So the real question is at running temps is the coolant circulation putting heat INTO the TB (which would hurt performance) or helping to remove heat from it (would help performance)

I am guessing it is putting heat into the TB since I doubt the TB is at the same temp as the engine (which is what determines the coolant temp) however then if that is the case, why do they route coolant through the TB to begin with?

^ My guess is they do that so that the TB does not freeze up in cold temps.

I agree with the replies above.

Being an old-fashion hot-rodder (my age is 46), my instincts tell me that anything that can be done to keep the intake charge cool will help power output.

Plus, my first-hand experience with the TL has shown me that the TL is SENSITIVE to ambient heat. I live in Houston, Texas (aka, 100 degree temps). I have felt the engine become very much less peppy after being soaked with the hot summer heat.

This is why I removed all of the plastic shrouds (including the ones under the engine and trans). The car now remains peppy in the summer heat. After installing the CAI and re-routing the TB heater hose, the car remains very peppy (to the same level of peppiness as being cool) even while the MID temp is displaying 101 degrees outside.

^ Yeah all good stuff, I also removed all plastic covers and it made everything so much more accessible and breathable in my opinion. I like the "naked" engine look under the hood. I did not remove covers under the egine though to prevent dirt and whatnot entering the engine room.
Please keep us updated on the IAT sensor relocation if you decide to go ahead with it, I can' t do it since I have an Injen unless I drill a hole in it, but I am wondering if it would help at all.

Inaccurate

ACTROS,

Here is a link that is dedicated to discussing the pros and cons to moving the IAT sensor.

Be warned that some people called the IAT sensor as a O2 (oxygen) sensor. It is *not* an oxygen sensor. It is an Intake Air Temperature sensor.

No problem, that is why we are all here!!

My car is shutting off it's a 2005 manual TL. I am waiting for a new ECU to come in to swap. I want to know which is the hot water hose for coolant to the tb so I can also disconnect and plug back into the coolant system
Please
I do not see the picture
