Throttle Body Question

SpyderGSX07 · 05-20-2011

Is it safe to loop the coolant lines going into the throttle body? i didnt know they needed to be cooled.. can someone explain why there is coolant going through the throttle body??? i have a 97 mitsu eclipse 4g64/4g63 head awd. Thanks!!

Its for cold start in winter to get your car warmed up faster. You can loop it and be fine.

When I did this I started getting idle surge because the FIAV (reason for the water lines) stopped working correctly. Once I blocked off the FIAV it was fixed.

Yep no problem looping them, hell I even had my heater hose lines looped at the end of my dsm days!

FIAV? and i did already loop my heater core.. i pulled all that HVAC stuff out.

FIAV = Fast Idle Air Valve. It's on the bottom part of your throttle body

Stop being a cheap ass ghetto DSMer. Get a FIAV blockoff plate.

You looped your heater core? Wtf is the point? Some drag car spyder? Won't you get cold on top down summer nights? If you're gonna loop the lines, you might as well pull the heater core, reduce weight...

And if this is some drag beast machine, get a real throttle body.

If you loop it, you should put on an FIAV blockoff plate on it. Or else you will be letting a small amount of air passed the TB plate all the time, which was only meant to be during warm-up.

You could just machine a plate plate and block off the whole bottom of the throttle body. It wont idle at all cold and you have to keep your foot on the gas until it is warm but you could make a whole block off plate yourself if you're cheap.

the heater core is pulled... again.. i pulled all of the hvac shit out. blower motor.. evap. HEATER CORE... and all of the plastic pieces with it all.. there is NOTHING under the dash. and there wasnt any point in having the heater core in. the blower motor wasnt working. so the heater core would basically heat soak and be pointless. as for the throttle body?? im leaving the coolant lines run to it. no point in having my car run like shit until it warms up because i wanted to loop some lines..

Good to hear about the keeping the lines to the TB.
Curious why you didn't just replace the blower motor and have heat?
