Cemetery Posted July 27, 2014 Share Posted July 27, 2014 Front wipers aren't getting any water through to them despite the rear ones working. Quick search on here & then one of my first plays around under the bonnet & it looks like the non return valve is kaput (only a tiny amount of liquid comes out when activated). Popped along to my nearest Halfords to get a new one to discover they no longer do them. Having now looked online there appear to be values for both 4mm & 5mm tubing...anyone know which I need?

neo Posted July 27, 2014 Share Posted July 27, 2014 my return valve was busted as well, just replaced it with some copper brake pipe, been like that for years, no trouble at all with the front jets now Quote Link to comment Share on other sites More sharing options...
GMballistic Posted July 27, 2014 Share Posted July 27, 2014 My non return valve went on my 350 as well. I bought a replacement from eBay which was a 5mm and that worked for literally a week or so before stuffing up. Honestly if I was you I'd do what I did and get a drill bit, ..drill out all the internal bits and spring from your old non return valve and just refit that. Or copper pipe as neo did. Don't get any problems with my washers now and the jets are much more powerful too which was an added bonus. Quote Link to comment Share on other sites More sharing options...
Cemetery Posted July 27, 2014 Author Share Posted July 27, 2014 Cheers, will take another look Quote Link to comment Share on other sites More sharing options...
Cemetery Posted August 30, 2014 Author Share Posted August 30, 2014 Having replaced the valve & it lasting about the same amount of time as GMBallistics, what size copper piping would be needed & what is the best place to get it from?

GMballistic Posted August 30, 2014 Share Posted August 30, 2014 Copper brake pipe is what Neo used but unsure on the exact size. I'd just drill out the internals of your old non return valve if you can as that's what I did which is the easiest option, ....otherwise something like this should work.

Ridz Posted August 30, 2014 Share Posted August 30, 2014 I replaced my front washer non return valve about a year ago. It was 4mm connection, which i believe is the internal diameter of the plastic tubing connecting to it. You can also get 4mm straight plastic connectors to replace the valve if you wish. Amazon or ebay are good sources for these. Quote Link to comment Share on other sites More sharing options...
MCook Posted August 31, 2014 Share Posted August 31, 2014 Just had both pumps, front and rear along with the valve replaced! Only found out on the drive home after just buying the car that they were both knackered Quote Link to comment Share on other sites More sharing options...
Cemetery Posted September 5, 2014 Author Share Posted September 5, 2014 Went with the 4mm version of these & it has worked a treat & much like you said, more powerful as well Cheers all. ..otherwise something like this should work.

scobie140 Posted September 5, 2014 Share Posted September 5, 2014 I blinged mine and went for stainless pipe instead of copper Quote Link to comment Share on other sites More sharing options...

Cemetery Posted November 16, 2014 Author Share Posted November 16, 2014 Grrrr...stopped working again, this time checked without any connector & nothing is coming out of the tubing. Searching here suggests either a fuse or a new pump...I cannot see anywhere there has stated which fuse needs checking however, does anyone know (will need a dummies guide). Given the Game of Thrones message that winter is coming is appearing to be true I think I will need these working sooner rather than later given the salt that will coat my windscreen in short order given the miles I am doing.

GMballistic Posted November 16, 2014 Share Posted November 16, 2014 The fuse is in the big black box behind the car battery I believe so is a right PITA to get to. As far as I'm aware there is only one fuse for both the front & back screen washer motors so if one works and the other doesn't then the fuse should be ok. If you check and the rear wash still works but the front doesn't, ...and you cannot hear the front motor going then it will most likely be the motors gone. You can get the front windscreen washer motor cheaply from eBay or Clark Motorsport on here. If I remember right it's only around £10 odd for an aftermarket motor. Fairly easy to swap the motors although I haven't done it but they can be accessed behind the front bumper on the drivers side. Easiest way to get at them is through the wheel arch liner rather than removing the entire front bumper. Quote Link to comment Share on other sites More sharing options...
Cemetery Posted November 17, 2014 Author Share Posted November 17, 2014 Ta, rear one works so sounds like the motor in that case. How simple a job is swapping them over/is there a guide for it as I am not that hands on normally Quote Link to comment Share on other sites More sharing options...

Link: http://www.350z-uk.com/topic/59243-how-to-change-washer-pump-motor/ When you take off the wheel arch liner and look at the washer bottle on the drivers side, ...the front washer motor is the closest one to you and the rear washer pump motor is furthest away (closest to the engine). They are different shapes slightly with different plugs so it's pretty hard to get them the wrong way round.

Cemetery Posted November 22, 2014 Author Share Posted November 22, 2014 Cheers for the above, have bought the pump, just tried to follow the guide & the bolt closest to the edge of the car will not undo, it is just turning whatever it is bolted to I sense a garage visit looming Quote Link to comment Share on other sites More sharing options...
