Hi,

My new G35 07 when cold and I give it a bit of gas a weird water bubbling/boiling can be heard from the cabin as if it is coming from the engine....Weird and Iam worried can any one try this and let me know if its the same in all cars. Some times even if engine is warm it can be heard.

 

Stop what ur doing,get in your car and drive it to the dealership RIGHT NOW!!!

Weird bubbling sounds? never heard that before

 

When the factory was filling your car with coolant, they most likely didn't pull a full vacuum on the system before they filled it. You probably have an air bubble that has found its way to the heater core.
The air needs to be purged out.

 

wow thnks guys....will take it to the dealer but is it bad if i drive it for 1 day or two by time they open?

 

Oh wow i am sorry, i left my tea kettle under your hood the other day.

 

i heard this noise in my car when i had a faulty connector to my cars computer. when the car went into 'limp mode' and i had to force the car to turn off by holding down the ignition button for 5 seconds, after it was forced to turn off, i heard the weird bubbling and boiling sound, and it did it every time i had to 'force turnoff' the car while in limp mode. i never could figure what it was but i think it has to deal with the air conditioner compressor

 

I've felt a similar thing in my car. I can actually feel a vibration that seems like bubbling through my clutch and/or brake pedal after I drive the car kinda hard (quick acceleration, etc). Someone mentioned a while back, after I posted about my clutch losing pressure, that the clutch fluid is near the exhaust and can actually boil. That seemed like a bit of a stretch to me, but I figured there might be something to it. Anyone else had any experience this way? I suspect it might be a similar issue.
