The nipple with the coolant leaked around it. The hose is now plugged, but is it supposed to lead to the throttle body before? Is it okay if it's now plugged?

Is the nipple threaded, i need to fix that leaky coolant problem.

this is a 98 gsr btw.

 

I believe on a GSR head that line goes to the throttle body...I know 99-00 B16's have that as well, and it goes to the TB. Pretty sure...

Might need a new housing if thats leaky, i know i ordered mine from my job (acura) and it was only about $12 I would replace it just in case

 

so if the throttle body is bypassed, does this need to be plugged up, or routed somewhere else?

 

When i built my ls/v, i was supposed to buy the one with that nipple on it, but i bought the one for a 95 del sol vtec, and it has it deleted, so i also had to bypass it. But, i had to tee off of the coolant line on the water arm so i didnt have any left over coolant hoses going to nowhere. I would imagine the only thing to be affected in your case would be the IACV.

 

it runs through the throttle body and to the iac valve so u kinda need it, you prolly need to buy a new one it might be cracked around the outlet
