I've heard pros and cons of doing this. I understand the gains are minimal, but so is weight reduction, removing the power steering, etc.. why are some people for it, while others are against it?

What exactly IS a throttle body coolant bypass?

And why does the climate of the car is in affect whether or not this mod should be done?

Thanks.

 

Hot coolant flows from your block to the throttle body to ensure the throttle plate doesn't freeze shut. In the process, it heats up the air entering the intake manifold, and as we all know, the hotter the air, the less dense it is. And thus, less fuel is injected with it and that results in a lower amount of power produced. The difference is minimal, and it is definately NOT recommended for people living in cold climates.. you don't want your throttle body frozen shut.

Thanks.

It's probably not worth it in the unpredicatble weather that is Michigan. 40 something yesterday, 70 something Monday..

 

I know what you mean.

 

But keep in mind, freezing weather means not just 32deg, but *** cold like sleeping with the Eskimos.

Anyone with the bypass living in a "cold" climate?

 

So if you disconnect it, will it spray fluid all over the place or what?

 

Thats a real intelligent reply.

Either HELP or DONT POST.

 

Anyone got a picture, or diagram of the best way to do this?

 

I wouldnt bother cuz you'd get a bad idle in cold weather and you might freeze your throttle body/plate shut.. if you live in cold climates I wouldnt recommend it.. and as for the guy who asked if you'll spray coolant all over the place.. what do you think? its a bypass not just disconnecting a hose and letting it spray/drip all over the place.. otherwise you'd be out of coolant in no time.. you use like a T fitting/connector.. to connect/bypass the hoses I believe.. but either way I wouldnt recommend it..

 

My car will never see sub 32 degrees. Plus, if I don't like the results, I'll just reconnect it!!

 

Yup, you got it! Car runs just fine with it disconnected in warm climates. Dunno how it would run in the frigid artic wasteland of Wisconsin though. I bought my '93 Teg with the coolant line ends plugged with a bolt and hose clamped. This guy seems to know what he's talkin about on the subject: http://homepages.paradise.net.nz/asmsbm/tb_bypass.htm

very helpful page, but keep this in mind... if you live in an area that does have cold periods... are you going to remember how to hook it up? and are you going to be too lazy or busy to go back and hook it up? don't risk your health (or your car's) if you live in a cold region.
