Hi there
I have noticed that when I turn the ignition off, after driving my V5, there is a gurgling noise evident. This can be heard inside th car and sounds like bubbling water/oil... I have lifted the bonnet and the noise is clearly heard form the back of the engine somewhere, almost by the windscreen.
The noise last around 5 mins or so after turning the ignition off????
Any ideas folks? Is this normal, as I swear it never used to do this?
Thx and Happy Xmas folks
-
any other symptoms like overheating or no heat from blowers?..
-
There is an auxiliary water pump fitted to the v5 and v6 engines. This comes on when the engine is turned off and continues to circulate the water for 5 - 10 minutes. I suspect what you can hear is the water being pumped around the system as is slowly cools down.

Hi
No other symptoms at all... no overheating or anything.... Think I will go for the water pump option... thx for this :smiley:
-
Didn't think you would have been able to hear the water getting pumped around though?
Or I've never heard it when people I know have turned there v5 and 4mo's off?
-
Never used to hear mine, its only been during this really cold weather that it has been so noticeable, soon as the pump stops noise stops.
-
never heard anything like that with the R32 just the fans would kick in
-
does this cooling system have its own water supply? could be that its leeking water therefore is pumping air and water through making the gurgling noise?
-
Normal really, it is the auxiliary water pump 99% sure on that :smiley:

Thx all... I am putting it in for a service in the New Yr so I will get it checked then... Thx again folks
