Throttle Body Coolant bypass

[Savage Messiah]

How do I do it?

[Chevyracincamaro]

i just figured my way through it, never bought one of those kits they sell:
drain your coolant
remove the intake tube from the throttle body
directly below the throttle body intake are two coolant hoses

i think they run from top to bottom between the pump and the TB. i just unhooked them and plugged one of the hoses across the two ports on the TB and the other on the two ports on the water pump. (so they are running side to side) i dont really remember too well so you might have to improvise something.

I never drained my coolant when I did mine.

So make the WP hose loop back to the water pump and the TB hose loop back to the TB, thats it?

[Chevyracincamaro]

thats what i did...

[Genopsyde]

what's the point of that?

you could pull both coolant hoses off the TB and join them? seems simpler.. and no you dont havta drain the coolant.. you'l just have a little bit leak out while your doin it is all..

an easy 3 or 4 horsepower..

Thats all I did, just went out a found a 3/8" coupling and bought 2 hose clamps. I forget is that was the correct size but those were the only 3 things I had to buy and coolant will only drip out of the hoses for the most part when you point them down.

[Savage Messiah]

So is that a better way? and how much am i looking at for 3/8" coupling and 2 hose clamps/ is it any special coupling?

[DaMoNe6969]

no.. even a piece of copper pipe that will fit inside the two hoses to join them, than you can clamp it.. your lookin at about $2 dollars?

[Chevyracincamaro]

i dont see why you need to buy the pipe. if you get it than you still have to plug the tubes that go into the throttle body. i recommend just using the factory hoses to loop the coolant passed the TB; take your 2 bucks and buy a job-well-done-soda...

[Savage Messiah]

So some people are saying to loop the water pump hose to the water pump and same with the throttle body; others say to basically delete the TB from the hoses and clamp them together as they would flow normally, just without the TB in there? First method sounds easier/cheaper while the 2nd method sorta sounds better. Any difference with either?

[Chevyracincamaro]

i dont think there is any difference. the second way (if i understand it correctly; as in the way that the kit does it) is just using a piece of pipe and some hose instead of the factory hose. it also requires to plugs to go where the hoses went into the TB (if you ever want to go back to the original setup).

the only reason i did it the first way is cause i was doing an induction service and at the last second remembered about doing the bypass, so i didnt have any pipe or hose bought. did all the bypassing with the factory hose and it works fine...

[Savage Messiah]

Doesanyone have any pictures? How big are the hoses? I was gonan do it today but wasnt too sure what I was looking for...

[Dober89]

i might have some pictures of mine kicking around but its a 3rd gen TPI.
