Throttle body bypass

[exelr8]

For anybody wishing to do this modification, a few words of caution...The coolant lines running through the throttle body serve an important purpose.  They provide essential heat to the Idle Air Control Valve to keep it from sticking in cold weather.  If you remove the coolant loop from the IACV, you run the risk of having the valve stick on cold days.  This will make your idle fluctuate and the car will sound very ill.  You may attempt this mod if you live in a no-snow state, but I still would not recommend it.  I have not done this mod simply because I don't want to get caught with my pants down when the cold weather comes around..

I just restored it to stock and said to hell with it, Where I live we hardly get snow but this year has been a bit wierd we actually got snow like 4 times this year

i went winter with mines done i had no problem just let the car warm up and you should be good to go

hell, I am still trying to figure out the difference in the coolant lines for Drive by wire like my application

This should be in a different forum.  Try to post in the appropriate forum next time.

seems like its the simplest mod to do. all the coolant does is keep the throttle body heated up to prevent freezing or sticking in colder weather. my friend had this done on his 93 civic. the car was harder to start in the winter and he did have to give it more time for the engine to heat up to allow the TB to heat up a bit too. but when he pressed on the throttle it was like nothin else. the TB kept pretty cool and the car ran great! i dont think it should take you more than 20 mins the second time around. so i think its safe to have this done for summer driving.then when the cold comes lurking around just connect back to head up the TB during winter. You dont need cooling for the TB during summer. if anything you want to keep it cooler

for the summer months it's fine.  I have had people ask me to diagnose their cars during winter time because of an erratic idle and they've all said that they bypassed the coolant lines.  Those coolant lines do not heat the throttle body, they heat the Idle Air Control Valve.  Heating the throttle body is just a side effect.

would this have any long term affects on the idle air control valve, thermostat or anything for that matter, even if just done for the summer months?

If the modification is performed correctly and it is only for the summer months, it should not pose any harm to the IACV or related equipment.  I would highly recommend making a mental note to yourself however that as soon as the weather starts to get chilly that you reverse the modification until the weather becomes favorable again.

yeah had it done when installed spacer kit. i guess ill chance when winter comes around

as long as you let your car warm up when you first turn it on, i don't think there should be a problem. then again, we don't get winters in florida, so what do i know.

jeff give us an update dude... how is this by pass working for you? what are the differences you have noticed.

[Jeff Likes Bagels]

Well, I've noticed a slight increase in throttle response... that's about it. My advice is that if you're willing to do a free mod with the potential risk of leaking coolant all over the place like I did, then go ahead. If you'd rather not have to potentially clean up that mess, and refill the coolant, then don't do it. The main reason I did it is because I'm obsessed with every little performance gain, lol.

[fabulous010]

same here. but dont have the money for big gains. hahaha thanx. i needed something to do today.

[Jeff Likes Bagels]

Yeah, now that I've done it, I'm satisfied. It's just the evil of having to do it, lol.

I never took off my intake; it was fairly easy to get to it. Just be careful, though. When you pull off the hose from the black metal tube that's under the IM cover a bit, it's going to leak coolant all over the fucking place. So be ready, and have the bypass hose ready to slip onto it.

Good luck. I'd recommend grabbing a bunch of towels (I couldn't find any in my house, AND we were out of paper towels, so i had to use NAPKINS lol).

i didnt end up doing it. i spent the day with the GF so i didnt want to bore her with that stuff. but i did look at the job and picked up the parts.
so just to make sure it is both lines close to eachother at the bottom of the TB?
