Water Running Sound on Cold Start

[JimoVTR]

Whenever I start the car up from cold I get a severely (well fairly) loud sound like water running through the dash?
and even sometimes from warm.

Whats up with my car?

You have an air lock in your coolant. These problems never have a happy ending… always lead to headgasket

[JimoVTR]

got the airlock out though!

Yeah got to agree, this does sound like a airlock. Had this on my saxo when i first brought it, i had to bleed it about three times before it cured the noise.

just re-flush the collant over and over until its gone

Simple :D
