Hissing/buzzing noise coming from engine

[eirkal]

Help!!!!

My car is making a hissing noise when on light throttle and stops when putting the foot down a little harder, it only does it when the engine has warmed up.
Iv been told it may be the purge hose, but it seems to be on there tight and not cracked or anything.

Whats wrong???

sounds like a sound i had...
changed the thermostat and the sound went away...

something like the coolant was overflowing and the sound was air escaping from the overflow bottle...
only was i could explain it... so check your coolant levels

Yea you maybe be right the coolant levels are a little high.
i might try changing the thermostat over the weekend, hopefully thats it.

isn't it just a case of taking of the top radiator hose at the engine side, not sure how the thermostat's connected..but just replace it, radiator hose back on..top up the system if you have to and bleed it?
