Coolant thru the throttle body ??

Why does the coolant run thru the factory throttle body ??

( People behind me right now fighting over who gets to drive my Vet right now )

I mean, I don't see any reason for coolant to run thru the throttle body, am I missing something ??
Does the coolant do something in the throttle body that I'm missing ??

Thanks

i heard that it was for Gm's anartica tests, and is only good at keepping the coolant from freezing at sub zero temps. Funny how it is gone in the c6 motors

From what I have read about camaro's (that use the same design).. it is mainly here for cold weather operation to help warm up the incoming air for better detonation... why you would want to do that I don't know... I like my air COLD...

its there to actually help warm up the TB instead of cooling it. I guess this would help in colder regions. Kinda like when the older cars used to use a heat riser. I bypassed mine.

It's there to keep the TB from freezing... some companies will sell you TB coolant bypass, but it's worthless.

It keeps the throttle blade from sticking when the condensation builds up and freezes.

It's there so you can spend $20 for the throttle body coolant bypass.

In some cold weather conditions (very cold, high humidity) the low presssure area in the TB can cause the Throttle Blade to ice up and possibly stick or effect driveability. The hot coolant running through the TB helps prevent that from happening. Thats the facts, plain and simple!

Mines removed!

You can make your own fitting from Home Depot.

Go to Home Depot and buy a brass 1/4" ID pnumatic airhose coupler. Remove the two coolant lines that conect to the bottom of the TB and couple them together with the brass coupler. Bypassed! By the way this mod shows no noticable gain.

I always wondered about the compatibility of the brass in the Dexcool and all aluminum cooling system.

Honestly, I don't know but the OAT used in Dexcool is somewhat acidic.

YOU NEED IT! IF you are going to drive up and hand deliver you letter to Santa. Other than that, dump it.

Looks like that proves it's worth about 6HP for next to nothing in cost! Now, if I could just find a way to do that 9 more times for the same about of $$$....
Hey, there in Idabel, OK, I'm not far away in Ponca City. You have any drivablility problems in the winter after the bypass? Mine is a daily driver except when it snows up here....

Good luck and happy modding

For next to nothing, it is definitely a worthy mod.
