throttle body coolant hoses
why are there two coolant hoses going to the throttle body? is it to further cool the air coming from the intercooler? or is it to keep the throttle body cool from the heat produced by the motor?

actually, it keeps it warm
the coolant is called coolant to cool the engine but in fact, it gets really hot.
it goes around the TB to prevent ice from forming and making the butterflies not being able to close. It is useless if you are from the south but if you take your car in sub freezing weather, it is usefull.

Does water flow through the tb to warm it . go look, or does it just warm the Hot Wax Rod for the fast idle cam . Look for your self I may be wrong. Do look, I think it does the hot wax rod ,not the whole casting. I do not remember a water jacket around the TB .

i don't know which hose is in and which one is out, but there is a coolant hose that goes to the bottom front of the tb and one that goes into the top corner (towards the firewall) off of the back of the tb. after reading your replies, i would think the coolant goes through the tb to warm it. sometimes i wonder what the mazda engineers were thinking when they built this car, did they expect to sell it in the north pole?

Its really easy, all you have to do is disconnect the hose at the top of the tb thats next to the firewall and just route it under the uim to the back of the water pump.
Its easy

yeah but you need to remove the spring on the hot wax rod too.
just check rob robinette's web site.
you might have lumpy idle at cold too, i had to adjust my idle after i did that.
but removing the manifold is so much easier now. No coolant on the floor again when i remove the manifold.

Oh yea, thanks for mentioning that...I forgot to mention it
Which brings up a point really. Most of you guys running this mod, did you remove the spring then screw the screw in all the way or did you do the "tie back" method that Rob used?

Why bypass it?
Unless I missed something... Is there some reason that you don't want to use the TB heating?
My concern here is that people seem to be removing a lot of things that Mazda Engineers put in for some purpose. I cannot claim to know if these parts are needed or not because I am not a mechanical engineer - but could this be the reason (not necessarily this case) that our engines are going *pop* so prematurely?
Why are you bothering to bypass a heating element that is doing you no harm - especially if you are not fully sure what that part does?

If you live in FL or drive your car only in the summer, then why have the throttle body heated? It's there to make sure the throttle body butterflies don't get stuck.

Also, I guess you guys are not at all concerned about resale?

RESALE? You have got to be shitting me?!?! I removed the unnecessary crap that the car came with because I work on my car. I DO NOT do stuff like this so that I can turn around and re-sell her.

the only thing the coolant does in teh throtle body is to adjust your idle speed and open and close teh throttle bodies, has nothign to do with throttle body being warmed, taht is a side effect.
