[Mk2] [NA] Water noise behind dash

[andy585]

my friend has a 92 n/a and i have noticed that when you rev out of gear there is a rushing of water behind the dash but no leaks what would cause this ???

You have a small air lock in the heater channels - a simple bleed will sort this. The bleed valve is in the frunk. Get some 8mm plastic hose from B&Q and read these instructions:

(service - howtos dropdown)

You'll only need the last few bits but you'll learn something.

Remember to set the heater control to HOT.

U may hope that the plastic radiator bleed screw isn't seized as was in mine. A real pita!
