Man i did that and my car not idles in 15 degree weather after a while at above 210 degrees thats messed up like all hell, and the cars temperature heats up a whole lot faster not than before to im going back to gm's way this isnt a good deal at all i thought it was supposed to keep it colder it doesnt do anything but make it hotter!

 

There's no possible way it could cause you to run hotter. You simply connected the line from the driver's side to the passenger side correct?

 

You may need to bleed the cooling system again

 

Hate to be the one to tell you, but doing the TB bypass does not make your car hotter. The TB bypass keeps your TB cooler by not exposing it to 200 degree coolant. Cooler TB=cooler air=more power. I had no problem idling at all up here in New England, where we saw -25 degrees two weeks ago.

 

Yes i went to autozone and bought the (2) 3/8 caps for the tb and a 3/8 plastic piece in between them as well i dont know what the deal is ive never seen my car run above 210 in 10-20 degree weather before. i connected everything back and all that i dont know what the hell the deal is?

 

Ditto on the coolant-bleeding procedure. Open the bleeder screws on the upper radiator hose and allow the engine to idle until no more air comes out. You'll need to repeat this process several times for the next few days, because there's plenty of places for air to hide in our cooling systems. Hot spots = bad = higher than normal coolant temperatures.

 

whats the deal, why do i need to bleed out the coolant did all of you have to do that but i still dont see because if i let the car cool as cold as it can be i mean it will still do the same thing so how will that help and can i just add more of the dexcool instead!

 

just went and drained alot of the coolant out and replaced it with cold anti-freeze and it still rose to almost 210 idleing but when im driving its like 160 or somewhere near? should i just go back to the old way tomorrow after school? can the 3/8 piece have to small of a flowing hole or something i mean i know i did it right!

 

You need to bleed the system dude.

 

tell me how i do that and please be specific!

 

Look up.

 

Bleed the system.

 

You bleed the air out, you open the two brass fittings on the line and when coolant starts comming out you close them up again. They actually sell a tool just for it but ou really dont need it.

 

so i just leave both of them open and coolant will flow out on its own and thats it? just as long i catch it when it starts to flow!

 

Hell, just use the conventional method. Open the radiator cap and let the car idle while revving intermittently. As soon as you cant see any coolant from the radiator cap anymore add some more. Repeat until radiator is full and no more bubbles arise from the opening. Close cap.
