Washer Jets
 

I need to replace the O/S heated washer jet and L-connector as both are blocked. It seems like 2 types of jet are available -

• 2-hole directional
• Fan spray pattern

Are one sort better than the other? I.e. Don't fail, clog less etc.

jets clogging especially on heated ones is due to using the wrong cheap additive .
Use volvo fluid which is spirit based and leaves no deposits at all . It is becoming very common now that wash jets go "out of adjustment" when in fact they are still pointing in the correct position , all that is needed is a suitably sized needle to prod the crystalised deposits out of them and correct aim is restored !

Many thanks.
I've heard of jets getting clogged because people in the past used washing up liquid etc, but never because the wrong type of additive has been used! I normally use Prestone screen wash or similar and haven't had any problems with any other marque.

Do you use it neat, or dilute it? I do nearly 30k/yr so go through quite a lot...

If you can unclip them and run vinegar through them that often dissolves any blockages.

It is neat , a one litre bottle is enough for 1 fill about £3.50 It is similar to methylated spirit, and burns with a near invisible flame !

I've used both kinds on my V70 and found that the non-adjustable spray ones spray a bit low for my liking. I switched to the two hole types and have been able to aim them a bit higher for highway driving.

Now I'm slightly confused? As my car has headlamp washers the manual says the tank has 6L capacity. A 1L bottle wouldn't be enough for a fill unless diluted?
Many thanks,
Nick

I would guess as the 1 litre bottle is 'neat' you would need to add 5 litres of water to fill an empty tank. Typically, a bottle of concentrated screen wash would have recommendations on the ratios for summer or winter use, so a 1:5 mix may not give adequate frost-resistance properties.

yes you need to dilute it .
THe table is on the bottle depending what temperature you want it to be safe down to

in UK down to -18C you will need to dilute 33% that is 2 litres of wash fluid to 4 litres of water for your 6 litre bottle ...

£7 to fill the washer bottle doesn't sound particularly cheap, but I guess it depends on how well it works.
Some of the super cheap ones are terrible, smear like crazy and you have to use loads to shift even a tiny amount of diesel film off your windscreen.
I guess the only way to find out is to try it. Perhaps a single bottle first though!
Many thanks!
