My waterpump went bad, I replaced it and I was still losing a small amount (12oz per 30miles) coolant. I thought it was the radiator but decided to do the pressure test.
Got a loaner pressure test kit from orielly and saw coolant pissing from just below the throttle body.





It's form a small hose about 8inches or so. Could not find the part # for this.
After searching, found this thread, but couldn't get part #.

Any write ups or videos on how to replace this would be great.

 

Get hose by the foot at your local parts store. I'd guess it's 5/16" but measure yourself to be safe.

 

make sure to change the clamps too, those spring clamps lose tension after a while. I was taught to never reuse them once taken off.

 

Depending on where you live, you don't even need that hose. Cap it unless you're way up north and freeze a lot.

 

Still don't need it. Delete PCV (or good catch can), then there's zero risk.

Bypass it, OP, or IACV will take out ECU.
