Heated washers

If one was too, theoretically, run the screen washer piping around, near (surface contact) or through heater matrix to heat the water. For obvious screen cleaning! would it be a good idea I would be worried if super hot water hit a frozen screen but I’m convinced that the water wouldn't get that hot and would lose some heat before getting to the screen.................... :unsure:

Or am I wrong on the above

discuss

fine and dandy idea. this was discussed many moons ago in my MGB days.

maybe I remember incorrectly but the job was to use a length of hose coiled around the washer reservoir;

my question is what are you trying to achieve?

If you want warm water squirting over your sceen then fine.

if you think this will help in winter then think of the following.

1. water will be frozen in the jets and tubes so the washers won't work

2. squirty amounts of warm/hot water will freeze immedialtely when contacting a very cold windscreen

3. the washer water will get warm once the main coolant is up to temp (if using the MGB solution), by whcih point you have a stream of hot air to heat the screen on the inside.

Now a small thermostacially controlled electric heater inside the washer bottle is the way to go.

Right

As a non smoker I'm off to borrow a fag packet to start the initial design stage :D

Get a coil of copper brake line wound round the exhaust manifold... Steam powered washer jets...!!! :blink:

Cheers

Jet warmers may work over here but in the proper cold its useless, the water loses the meagre heat gains long before it hits the glass, its a bit less aggro to just use decent low temp screenwash, we used to use neat rum but now use a eastern european screenwash thats 80% by volume. never freezes and almost melts bugs off in the summer, 40p a gallon :D

There is a bloke on Ebay sellling a pipe that replaces the long metal heater pipe that goes across the cyl head. It has a coil round it to heat the washer water.

Now we all now how long it takes a TDi to get up to temp...... :blink:

You guys are funny. It doesn't get cold enough in the UK to need such things.

Come on over and try -40 C and we can start talking.

Had to stop of at Halifax one winter for water to see us across the back across the Atlantic. Yep, that was COLD!!

Your right though and living within a stones thow of the sea I don't recall even having to scrape ice from the screen in the 5 or so years I've been here.

No snow though :(

The worst I've had was up in Aberdeen (in the city itself - it was colder in land). I think it was about minus 18 or 19degC - in any case, I made the mistake of trying to wash the screen... The screenwash was the best we could get and neat, but only rated for -15degC - it partly froze in mid air and arrived on the screen as foam, which promptly set solid and rock hard. Took me ages to chip it off. I had deicer in the car, but it was an aerosol and they don't work at that temperature :( Minus forty must be a real pain...

Heated windscreen and washers on the rangie means I don't have that problem any more :) Although I've already had the washers on the escort freeze up, and it was only just freezing. Takes ages to heat up and demist as well - I want my V8 back :(

They don't actually say much about what it does...but it looks like it achieves pretty much that same as siggy is planning?

It is a thermostatically controlled, electrically powered washer fluid heater. The problem with using coolant to heat it is the washer fluid will evaporate.... You see in places that are cold, you don't use water in the washer tank but an methanol based fluid that doesn't freeze. It also evaporates easier.

A possible good cheap solution would be to run a little tubing in the air ducting after the heater matrix. This shouldn't be too hot and will only be hot when the heater is going.

Oh, I was waiting for quibble like this! Right, that's called "local perspective".

I think the easiest way to overcome the problem is to increase the concentration of alcohol in the cleaning solution. That's what the funny people do in those remorte parts of the world.

I'm sure I saw something mentioned in Autoexpress not long ago that did the job as you say. Can't remember who made it though, might have been Holts.

There used to be a product that was a small cannister in series with your pump that stuck to the block with a magnet but I haven't seen that in years, not much good with a V8 though :rolleyes:

I did the thing with the long heater pipe on the Rangie when it had a Perky in it, 15mm copper pipe, slide a 15-22 adaptor on, slide a length of 22mm pipe to taste, slide on another adaptor, drill a couple of 6mm holes at either end and stick 6mm copper stubs in. Solder the whole lot up plumb it in and away you go. It does work and is very effective, particularly during the summer for removing bug splat. I keep at least 20% antifreeze wash even in the summer. Heated jets work very well too.

Any temperature of water will freeze when it hits a screen that is below freezing due to the large cold surafce :blink:

Guy what you need is two sets of keys...use one set to start the car and then the other set to re-lock the door...go inside in the warm for a nice cup of tea and when you come out again warm car and clean windscreen....works every morning with my transit at 6 am
