 How to defrost windscreen washer? - Fursty Ferret
I haven't refilled the washer fluid on the BMW since I bought it in November; it seems to have a cavernous container. Unfortunately, with the cold weather and the fact that BMW appear to have filled it with plain water, it's frozen solid. Peering down the filler neck reveals a solid column of ice, and despite driving 45 minutes today it hasn't melted at all.

I have two bottles of neat screenwash ready to go in, but I need to get the ice melted first!

Innovate suggestions required (other than taking it back to BMW with a Post-It note saying "Fix this please" stuck to the windscreen).

Put it in a nice warm aircraft hangar, or in your garage with an appropriately placed fan heater. You will need to get the whole system warm enough to thaw the pipes as well.

Boil the kettle, pour it in :-)

It's made of stern stuff, it can take it. None of this paper thin nonsense on lesser marques.

Can the pump withstand freezing?

Is there space for much fluid as it stands?

If so, pour in the neat screenwash which will at least stop it freezing any harder.

Expansion has probably already taken place, hopefully it hasn't cracked the bottle.

Blank the radiator with a bit of cardboard. Empty the oil out of the sump, or simply remove the sump plug. If you don't know where it is, ask Quickfit. They might even do it for you if you smile nicely. Drive flat out in second gear for 20 or 30 miles. When the water temperature warning light comes on, park in a warm garage leaving the bonnet closed. That ought to do the trick.

If it doesn't, try to set fire to the engine bay by pouring petrol or paraffin over the engine and igniting it. When it is well alight, shut the bonnet. Wait till the fire goes out. Even if it doesn't melt the ice, it will melt the screenwash reservoir. Then you just chuck the residual lump of ice away and ask Quickfit to repair any damage.

Failing that, what about an old-fashioned tosher's blowlamp?

Seemples as people keep saying.



Note: if you are tempted to try any of these methods at home, don't.

No reason in particular, but just don't.

How about putting some plain water into the Eishöhle, and inserting one of those portable water heating devices for tea making? Here's one - tinyurl.com/2voq4yf Chosen at random for illustration only:)

Hair dryer or hot air gun. If using the latter, be careful not to melt the insulation on the surrounding wiring.

Or melt the plastic bottle.

Good point.

Once got into enormous trouble for using the wife's hairdryer to dry out some condensation in the headlight of her Ford Ka after changing the bulb. Didn't want to use the hot air gun for fear of damaging the polycarbonate lens or burning the paint but the hairdryer was never the same again (maybe because I went to the trouble of untangling the mains cable, but that's another thread).

Drive for another 45 minutes. Once the thaw starts it works its way through pretty quickly.

Once it has melted, somewhere in the 'Bargain' thread on here you could buy 5litres of concentrated screen wash and get 1 FOC. Thanks to whoever recommended it. I bought some, and it was delivered to my home carriage paid. £5.99 for 10litres was a good deal..only 5 minutes on t'net and no messing about in shops.

Yes, very. I'm not covered in shame exactly, but I hope ON and NC won't take my rudeness in another thread too much to heart, especially ON who says (and I believe him) that he used to do tail-out slides in an HGV 40 years ago.

Having never even driven an HGV or artic, I feel I ought to nibble a small piece of humble pie for breakfast. And the brandy butter hasn't even been made yet. Ugh.

All is forgiven, I had my suspicions. I did power slide a RAF 5 ton truck through a 180 deg turn on their parade ground.

I was suitably ear bent by the owner, who marched off muttering about matlotes.

I belive it is called "drifting" these days. :-)

Use a greenhouse heater on "low" and a plastic tarpaulin to keep the draughts out.

Use a washing up liquid bottle for now with a 50/50 mix of windscreen/w fluid, and wait til it thawz.

Why the windscreen washer container is made of plastic instead of metal?

If it were made of metal, then engine heat would have kept it warm all the time, which in turn would have helped cleaning the ice from screen more effectively.

To check the washer level, a narrow transparent glass window could have been on the side of the container.

If memory serves me right the one in the Moggie Thousand was glass - which was pretty potty - it may have been an aftermarket one !
 How to defrost windscreen washer? - FotheringtonTomas
I remember the originals as being plastic (polythene), and holding about 1 1/2 pints, clipped to an inner wing by a spring clip like a cyclist's trouser clip. The tube went into the bottle through a hole in the cap. The washer was operated by pressing a pump on the dashboard with a finger or thumb.

If it had "co-op dairy" on it, yes it was non standard.

Because modern designs dictate the use of very irregularly-shaped washer fluid reservoirs to fit in wheelarch spaces etc. This would of course be prohibitively expensive done in metal.

To thaw out the system, pour boiling water into whatever space may still be available in the reservoir. Go for a longish run to get the underbonnet as warm as possible (though not as warm as AC suggests!). Park in as sheltered a spot as possible and drape heavy blankety stuff over the bonnet area. Try the squirty thingies at regular intervals - once fluid issues from jets, keep operating the pump to drain the reservoir. Re-fill with an approriate washer fluid.

Now in advance I want to make it utterly clear that I'm not recommending the following and will not risk it with any of my cars but...

I was in a London cab this week and got chatting to the really quite elderly driver. Well I say elderly, he looked it anyway. Been a cabbie all his adult life he told me. Certainly knew his way around.

Anyway, we got onto the weather somewhat inevitably. I mentioned that no matter how strong the concentration of my screenwash it had still frozen once I got any speed up and thawed again when travelling more slowly. We didn't discuss the impossibility of that as he agreed it had happened to him too. However, the advice he gave astonished me.

He claimed that he put a tablespoonful of antifreeze in each fill up along with just enough normal screenwash to act as a detergent and had never had the jets freeze since first trying that decades ago.

I remarked that it must surely damage the paint or the mechanism but he assured me it didn't in that concentration.

Interesting at least. Still not going to risk it though !

His cab was immaculate by the way.

If it works - don't knock it. Don't know how a tablespoon can do much harm?

Obviously, you are using the weaker screen-washes made for the British market. Buy the ALDI stuff next time it is on sale. It is designed for the Continent and claims to work at temperatures as low as -70C if used undiluted.

>> frozen once I got any speed up and thawed again when travelling more slowly. We didn't discuss the impossibility of that

oh no, not windchill factor again! :-)
