hi, im new here. i have a 08 Fit sport. in the past few weeks i heard some noise under the hood when i start the car.(i can hear it inside the car) it sounds like boiling water. it happens when the car is cool,(ei. at the morning). when the car runs few minutes, there is no noise. (the car is fine, everything works well)
wats that noise???? form ???

 

bro i have the same thing going on. sounds like swishing water or something...

 

water circulating thru the heater core, check anti-freeze level when cool.

 

I thought the aquarium noise was normal since it's been there for a long time. It makes my passengers want to P. My coolant overflow levels are perfect but I'll check under the cap too.
