Vent hose question.

NH335i · 06-22-2013, 08:46 AM

So I got lucky and it was just something minor and nothing big.
I was leaking coolant everywhere. So I starting pulling the intake off to get a better look. I was gonna keep tearing it down untill i found the problem or got the radiator out. Whatever came first.
Well i got lucky and it was the very firrst thing I could see. Vent hose running accross the top of the radiator.
So heres my question.
I would of had to wait for the part a few days so I just fixed it myself.
Does that tube have any sort of heat characteristics that would make it different then a fuel tube.
The piece i used is the same thickness and its nearly identical.

Anyone think it will melt?

Most plastic melts at well over 1,000 deg F. Engine coolant usually runs between 180 and 230 deg f, so it shouldn't melt. But I think you should at some point replace it with the OEM part.

Ya.
Thanks. I figured it would be fine. Just wanted a second opinion.
