Does anyone know what the swooshing water sound when turning is by passenger seat. Discovery II Series?

 

I had the problem too. As it turned out, the swooshing sound was caused by a low coolant level. Once I had the leak fixed, the problem went away.
Keep an eye on the level as I nearly overheated in stopped traffic heading to the dealer.

 

she probably has a seven seater and yes low coolant or an air pocket in the lines

 

i just had my 03 disco II serviced for the same problem and it turns out that the coolant level was low due to a leak from one of the main coolant gaskets. it was not expensive, and was a quick fix.

 

If you want to e-mail me off line I will walk you thru bleeding the air from the coolant.
