Windscreen washers have poor delivery, how do I increase flow? (1 Viewer)

[ambulancekidd]

We have a rather elderly year 2000 Autosleeper Executive & while I really like the rear motorhome part of the vehicle, the base vehicle a Peugeot Boxer 2.5 turbo diesel leaves me cold. It seems comes over like a British Leyland vehicle of the 70s or in other words its built to a "that'll do" standard.
The latest problem is that the windscreen washes have a rather poor delivery, its has the flow rate of an elderly man with prostate trouble. I was going back through the vehicles MOT history & noticed that this had been a problem in the past. Now can anyone tell me how to improve this flow rate? The current flow barely reaches the screen.

I'll be very grateful for some helpful advice.
Robert.

Well the obvious first thing , it fact so obvious I hesitate to mention it, but they aren't blocked are they.

I don't know the specifics of your Boxer but there is a generic problem for screen washers. A build-up of black gunge can block the filter located at the base of the washer bottle or tank. Cleaning the gunge out improves the flow rate considerably.

Hi, if the jets are not blocked, remove tube from jets and run into a container to check if there is gunk etc in the liquid and tank. The inlet to pump could be partially blocked. Flush out tank, if not successful there are lots of option on flea bay from a complete system to pump replacement. Hope this helps!

On my car i had poor washers. Changed the non return valves and all back to normal. Must admit i was surprised how much pressure is required to open the new valves, could not blow through them. But do agree check for blockages in jets and pipes first.

They wouldn't work right on Julie's car and found blowing down the pipes backwards cleared a lot of soap out that was forming bubbles and air locking it, she uses far less additive now and they are fine.

I like your thinking as it wouldn't be the first time I've missed the obvious lol, but no they're clear thanks.

OK thanks I'll try checking further back in the system to see if there is any crud in the pipes. The system on these vehicles just seems so badly made. I've never had problems like this in 40yrs of driving, I'd popped the posting on hoping that there was some kinda upgrade lol. We live n learn

at the age of your van it is not uncommon for the feed tubes to start to break down and go sticky. pull the pipe off at the jets and check the flow rate. if bad pull off at the pump and check flow. where you get good flow, you know the fault is after this point
I have had to re-tube several older vehicles over the years and the difference is remarkable

I'm liking your thinking @TheBig1 you might just have hit the nail on the head. The Sprinter we have just about blows the windscreen in when the washer button is hit, this system kinda took me by surprise, but I'm nothing if not willing to learn. Many thanks folks.

Scrap yard get another pump Fiat Peugeot renolt all the Sam vans just distant names think that will fix the problem
Put a Calvin solution through
To decal the system or sum malt vinegar over night but don't let it get any whare near the body work then flush with lots of fresh water
I would start with the pump first Fiver at the scrap yard or just stick it in your pocket
There only push in and held in with rubber grommet

No Leyland vehicle of that era would have survived for 17 years. Failing screenwashers is simply a service item .

Main problem is cheap poor quality washer fluid which eventually forms a black gloopy gel in the reservoir and clogs the filter.
Next mistake is being tight fisted and using washing up liquid in the tank with the same end result.
Washer pipe is cheap enough so maybe replace the old hardened and brittle hoses with new ones.

The trouble is that even though the vehicle has a full & comprehensive service history I have no idea what previous owners have used in the screen washer bottle. I only ever use good quality washer fluid, but I'm going to drain it down & clear the bottle out, new pipes & possibly new washer jets. I'll cast an eye over the pump itself, I suspect that its crap quality. I bought this vehicle as a wee project & knew that it'd need work, but its been a proper pain. The motorhome bit of it is pretty good, but if I'm being honest I hate the bloody stupid poor quality base vehicle. We still have our Sprinter & despite that being half as big again as the Peugeot there is no contest on the quality, the Sprinter drives like a car & just never goes wrong, three years constant use & the thing just drives perfectly. Maybe I'll need to dig deep & buy a motorhome on a Sprinter chassis lol. Anyway I really do need to get the pressure up on the Pug, I could sweat faster than the jets work.

My mum's car was bought from an old man - I guess that neither she or he would have filled up the windscreen water but would have relied on it being done when they took it to their garages. The flow rate to the windscreen was terrible when I drove it so I investigated and found a load of clear slime in around the outlet filter of the washer bottle. I drained the tank & refilled it but with plain water to run through the pipes until all the pressure picked up to an acceptable level & then added screen wash. It worked well after that.

I'm not aware of what the slime consisted of unless it was the product of some reaction between screen wash solutions or that it was the accumulation of years of wash being added and separating into detergent, water and antifreeze while the vehicle was motionless.

Just a quick note to say I had the same issue on y recently acquired 2004 Stargazer. Having read the tips here I went from no flow at all to having to adjust the jets so they weren't hitting the roof!

Thank you ... and now, as I guess you can tell, signed up for the Forum.

Just fixed mine - same problem 2001 Ducato

Renewed tubing but it was the non return valves that were the cause - tubing and valves about £8 off ebay

I just replaced the jets, pipe and non return valve on mine. Cost just under £10 and took me 20 minutes. Really strong powerful jets now. Lovely.

Ebay is your friend for the parts.

Endoscopy then a really painful slice and dice to see if it needs removing, tubes and all for a full replacement

 

[G-RMPS]

My three jets went to two sprays, then went to one dribble, and finally nothing.

Six small tye-wraps reattached or secured both ends of the hoses. Now I can where I am going

When I was working on buses we inherited a fleet of old Leland Tigers and Olympians. The washers were a joke. The pressure was so low it wouldn’t reach the screen on a windy day.
We found the pipes were squishy and nearly blocked. In the past some one had put neat screen wash in the tanks. New pipes from the pump to the jets, not an easy job, restored the washers.
The washers on one of my Landrovers were modified and fitted on the arms next to the blades. It certainly put plenty of water on the screen but the pipes split were they flexed regularly.
