Hey all a friend of mine mentioned to me that he heard theres a Throttle Body bypass in third gens. He wasnt too sure being that he owns a 4th gen so is there a throttle body bypass for our cars and if so how easy is it to do I helped him with his and it was a pain in the ***. Thanks in advance.

 

yeah all you do is bypass the throttle body. take it out of the path of the coolant going to the heater core. there used to be a hose kit you could buy, think it's gone now. All I did was run hose from fitting on the manifold to the heater core. And ground off teh coolant vein on the bottom of the throttle body before I polished it

 

Sounds a lil complicated any pictures to give me a better idea ? I already did the by pass with the removing the heater control valve will any of that cause a problem to do the Throttle body bypass ?

 

You've got 2 hoses running coolant through the TB. All you have to do is unhook them from the TB and then plug them together using a small piece of copper tubing, or get a new hose and run it on the same connections as if you spliced them together as above but it's one hose no splices/connections. It's really simple. No, it won't hurt anything unless you are like in the far upper northern region of the country.

 

Oh ok i did the same thing when i did the heater control valve bypass. I used a plastic connector to connect the 2 hoses however. Couldnt I use the same type of connector for that instead of a copper tube ?

 

the red arrows show the new line i ran bypassing the TB

ahh got the pic in much better

 

Oh ok so i take out the hose thats under that hose at the top of the TB and run it under the air filter thing if im right. Correct me if im wrong.

 

take the air bridge off(black acordian thing) you will see that on the bottom of the TB there is a hose that brings coolant to the TB from the intake manifold. That is where the TB gets it coolant if you unhook it the tb will get no coolant. get a new hose that will go from the fitting on the intake manifold to the heater core. just like you see on mine. then you will be all set.

 

I dont want to sound dumb, and i understand everyhting you guys are saying, but why does coolant go through the TB to begin with? 89Warbird said something about northern regions shouldnt do it so does it thaw the TB or something if things are reallllllly cold?

Anyway, is there any reason Not to bypass it?

 

Some guy is selling them on ebay. Will the throttle body actually stay that much cooler with this mod?

 

Nitsuj86Iroc...

coolant goes through the throttle body to warm it up in the winter- bypassing it will cool your throttle body down being that there wont be hot coolant running through it- cooler air in the motor=more efficient. but when winter comes you might want to connect it back up to make it run a little better.

 

i noticed a touch more throttle response from the mod

 

OK thanks, I wont be driving it in the winter, so Ill go ahead and do that when I flush the coolant.
