Hello all,
i have got an issue with my 02 wrx,recently had new rad as it was leaking now ive got a noise behind the passenger air bag area that sounds like water splashing around,when i rev the engine or just pull off it actually sounds like somebody in the bath or a coke bottle being shaken about,any ideas would be most gratefull
thanks
alan.

 

Coolant system not bled fully after rad swap.
The noise is air going through the heater matrix.
