I was wondering if anybody happened to know what these two coolant lines were? The first one is coming off the thermostat housing and the other one is located on the passenger's side of the engine bay.

Thanks in advance,
Rob


sorry this pic is a little blury, but its the blue piece.

 

Runs from the thermostat housing to the bottom of the air regulator, back through the throttle body & dumps to the line down behind the alternator.

 

thanks again Nismo your the man!

 

or you can plug them like me, or even connect them like i had them after i took out the egr vacuum control.

 

Yup I plan on plugging them, just wanted to make sure they werent important.

 

I bypassed the TB but left it for the air regulator to make sure it opens & closes at the right temp:

 

the part under my regulator controlled the egr, i dont got one, soo....... gonzo! the air regulator on mine is electric only, diff. in later years? has no temp differental

 

I have megasquirt so I threw pretty much all that junk in the trash

 

know how people remove the air regulator to clean up the intake mani.... will that leave the idle all the way up high? or all the way down low, cause up high for me would be about 1500RPM down low, about 800rpm. lol.

 

It usually only affects idle when the motor is cold. Running the stock ecu & removing the air reg will cause low / rough idle for a minute or so.

 

bitchin... thats all i needed to knowsept when you remove it, doesnt the idle screw get removed with it? its like, part of the system isnt it?

 

not on mine, you just gotta plug some holes boy. maybe on the later ones tho.

 

thats all i need to hear. well when i do a headgasket and put my N42 on and such that air regulator is GONE! mine probably doesnt even work any ways i dotn remember hooking up the wire labeled for the air regulator i think i just grounded it like it said to if not using it so meh!

 

Thanks, I was wondering if I could plug the lines too and was about to do some reasearch on it. Thanks KTM200-280zxt for asking what I was about to research.

 

Haha no problem, you would just have to take out the air regulator and like Nismo said you would just run rough at idle when you first start your car.
