Strange Noise From Around Fuse Box

[em_ar_two]

gonna have to ask you coz its seriously doing my head in now, but ive repeatidly heard a sizzling hissing sound coming from what appears to be the round canister behind/next to the fuse box located in the rear left of the engine bay, on minute i just have the lid open on the bay and im just there and all of a sudden it'll start hissing sizzling for just short of a minute and just stop and it does it every now and then

for example i fitted a k&n and during fitting it it must have made the noise about 3 times, first i thougt it was the fuse box but appears to be the black plastic caniters located just behind it. on a 3sge engine, from what i can make out its something to do with either the fuel or the brakes i think

[em_ar_two]

I was always told when you get a noise you dont recognise, thats been there for a while.

Start worrying when it stops

i also get this, I have gessed that it water escaping from the rad cap into the overflow, when the coolant is hot !?

Puts my mind at rest any ways...never had any problems from it, and have always had it !

[dj_davo]

i get it too.

always thought there was a secret snake or something in there!

im glad its normal and everyone else gets it. :D

Its the charcoal canister, dont worry about it. The other noise that you might hear is bubbling water flowing back to the resevoir after a hard run, thats normal too.

[dawolf]

Mine makes that noise too, lol. I'm sure it sometimes does it when stone cold too.
