A friend asks if these are obtainable. Suitable for a new Yaris.
I'd have thought using a suitable washer mix would meet most requirements.

Although many years ago I did make a little brass heat exchanger that plumbed into my Mini heater and screen washer system!

My focus has heated washer jets but if the screen wash freezes they are useless, I use a 50/50 mix of good quality screenwash in winter and have no problems, and didnt with my last car which did not have heated jets. I remember a heat exchanger device similar to the one described by GWS from many years ago called a "Hot Wash", which was certainly not "brass" quality.

When I drove a Sierra the screenwash was stored in a plastic bottle under the front wheelarch.

No matter how much screenwash was used, it always froze at about 6:30am on cold frosty mornings.

The position of the washer bottle is critical.. if it is in the airflow, and it is really cold.. it will freeze...

My screenwash mix doesnt freeze at -20C in my freezer so I think I will be OK. Wind chill does not effect inanimate objects, my external temp guage doesnt drop with speed. The Focus washer bottle is under the offside front wing.

Wind chill does not effect inanimate objects


Sorry, but as far as I know wind chill affects any objects which contain liquids, such as a human body or a plastic bottle full of washer fluid.

Wind chill is caused by the wind increasing the rate at which heat can be conducted away from a liquid through a surface. This causes energy to be lost and the overall temperature to decrease.

Or something like that, my A level physics was 25 years ago!

It doesn't matter what the wind speed is, a thermometer will still record the same temperature.

My old (wedgie) Austin Princess had the washer piping pasing through the inlet of the heater air box. Guaranteed to keep the liquid at whatever the ambient temperature was.

Please lets not go down this road - already discussed at length in the above thread and that thread refers to another thread (along with a link) where it was discussed before. Link through by all means !

Bit like one of those Russian Dolls.
