First, the mod is where you cut off all antifreeze going to the throttlebody.

Second, should I put it back to stock if I am going up to the mountains? I looked at the 5 day forecast and it's expected to be in the upper teens / lower 20s at night and above freezing during the day.

Thanks guys.

 

let the car warm up for a little while before u drive it is what id say u wanna let the engine warmth get to the TB

 

You don't want the butterfly to stick......... You can switch it for your trip and switch it back when you get home, or like warm it up first.

 

thats true too or u can just leave it alone lol

 

What does this mod accomplish? I've never heard of this.

 

Don't remove this mod!!! I live in Minnesota. About two weeks ago we had like -30 Below Zero! I have done this mod. I never had any troubles at all! I don't sit and warm it up ether. I (of course) take it easy on him when it cold like that. But I don't sit and run it. I just drive! So should you. Just don't worry. It will be fine!!

 

Throttle Body Coolant Line Bypass.

Keeps the hot water (180-ish degress) from heating up the throttle body, which then transfers a little heat to the air charge. Just a litte help (if any) to keep the air charge as cool as possible.

Look up the original post by innaccurate for pictures on how to re-route the coolant lines. Very easy.

 

i have had this mod done for a while now and my buddy has an rsx type s which has been done for about three years now and we have never had any problems. i live in NC so the temps only get down in the teens at its coldest.

 

Here it is...

TB Coolant Bypass Mod...anyone do this? (click here)

 

i dont know about driving right when u start the car.....oil does get thick in cold temps and takes some time to thin out and circulate. in the manual they tell u to let the car sit for one to 2 mins. then you can go at a nice pace til it fully warms up...i let it sit for 5 mins if its insanely cold.

 

I've had mine in the low teens in Lake Tahoe for a short time with this mod and no problems.
