Leaking washer jets.

Post by **rambo** » Sat 03 Mar, 2012 21:29

Can anyone help in giving advice on how to stop water leaking from the washer jets after use on my 99 Z3 2 litre? I assume it may be a non return valve some, if so is there one or two and where is it situated?

I seem to remember the NRV is in the jet.

Other than checking for grit/other contamination, they're not too expensive to replace.

If you have heated washer jets then the NRV is part of the jet. if not then look for a white 'device' in line in the hose close by. To get to either you need to remove the under bonnet soundproofing blanket. there are special hose clips as well that need a special tool to remove, although you could probably replace with micro jubilee clips.

I suspect crud an calcium have just been building up for a while and now block the valve. BMW actually mention that their washer fluid prevents this. Then they would say that, wouldn't they. I had a 'drilbler' a while back. Mine was a heated jet, so not cheap to replace. I managed to get it apart and clean it out. if you do the same, watch out for the tiny springs and small rubber inserts. they can ping a long way.

And chrome z8 replacement nozzles fit if required.

Thanks for the help guys.
I'll get on to it as soon as I have finished decorating the Lounge; penance for too much time in the garage.
Regards to all for a great forum.
