Whats a washer delivery valve?

Networkguy · Jul 2nd, 2002, 20:26

Well I have just picked up my S70 from it's 70k service and the only unexpected thing was 3 x washer delivery valves. All cost less than £3 and there was no labour charge to fit so it doesn't bother me.

But what the hell are they, what do they do and why 3 not 4 (basing this on 2 for the windscreen and 2 headlamps).

Cheers

PS

I am well chuffed that I have managed to get 60,000 miles out of a set of front brakepads and 70k out of the back.

I think they're a sort of non return valve on the washer pipes, stops the pipe empting back to the tank..... I reckon you only had 3 beacause:

1. You only needed 3
or
2. There are 2 for the screen & 1 for the lamps

Just some musings........ ;)

I will go with that. I had one of these non-return valves fail and until I replaced it wondered why the washer jets were so pathetic.

I must admit that the washers do seem to have a bit more power behind them now.
