This is off of my Y8 swap and for some reason there is an obd1 Z6 Intake manifold on there with this line.

On my Z6 the line goes where I have pointed out, but the Y8 as you can see already has a hose going from the FITV to under the intake manifold.

Where can I direct this coolant line or do I need an OBD2 Y8 IM and it would rid me of this problem.

 

also would this cause the idle to go up and down?

 

its coolant... you get rid of that and only use one hose... form the block to the throttle body

 

yeah I tried blocking off that hose but coolant leaks thru no matter what I plug it with.

 

lets see... you should have a coolant hose go from the block to the throttle body, then from the throttle body to your IACV, then from your IACV back to the block

 

that's right... but then theres also this extra line since it is a Z6 intake manifold. the line is running from the top of the 4th runner which i drew an arrow to and its suppose to go to the throttle body according to my other Z6, then to the IACV and on to the block.

 

take it out... when you put in an aftermarket intake you lost that line

 

take what out if i take that line out it pours coolant all over the vtec solenoid it's a stock Z6 manifold on a Y8 head.

 

yeah... take it out... and where it connected to the tb from the block put in a new single line

 

wait a sec i dont understand lol sorry im dumb... ok
1. coolant line comes off the block somewhere under the IM and goes to the TB.
2. line goes from TB to IACV
3. line goes from IACV back to a different spot on the block.

that's all ok but I have that additional line ontop of my IM beside the vtec solenoid that on Z6s goes to the TB where the #1 line went with that pipe thing i have in my hand.

 

ok... if you got rid of that thing in your hand... all you need is an extra hose, one that will...

1. Go from the block to the tb
2. Use another hose to go from the tb to the IACV
3. Go from the IACV back to the block

there are 2 coolant lines that go to the block...

 

ok ill pull that pipe thing off and just block the hose like i had before but find something better so that no coolant leaks through

 

i dont know if you got my message... but all you need is a y8 tb... i now just saw the line above the tb and if you get a y8 tb it doesnt have that and then route like i said and you will not have any problems

 

yeah but changing the TB won't get rid of this extra line i have blocked off.. its on the intake manifold not on the block at all.

 

hmm.... maybe you need an obd2 tb... i think thats the answer...

 

yeah I'm gonna look into gettin 1, thanks for all help, i see ur from chesapeake i got this y8 swap from a guy down there i 4got his name but anyway he failed to mention there was an OBD1 intake manifold on this and a hole tapped in the oil pan for turbo lol I wasn't paying as much attention as I should have when I picked it up to catch some of these. thanks again for the help bro

 

I would just get the y8 manifold its better anyway I did a mini me in my crx with a z6 head but I heard the y8 was a better manifold im sure you could find one real cheap, it would fix your problem and improve air flow
