Windscreen Washer Aiming Diagram?

[PhilipK]

The windscreen washers on my 2008 (facelift) IS250 feel to me as if the jets are hitting the screen too low down.

Pressure is fine, and the screen does get cleaned, so perhaps the boffins at Toyota designed the system in such a way as to allow the airflow to spread the washer fluid over the screen, but the point where the fluid hits the screen just seems lower than in my other cars.

Does anybody have an aiming diagram showing at what point the washer jets should hit the screen? (I know that BMW produce these for their cars.)

Supplementary question: Can you just use a pin to adjust the jets, or is that likely to damage them and you should really use a special tool for adjustment?

(One thing that I do really like is the additional "drip removal" sweep of the wipers that is done a few seconds after cleaning the screen. On my other cars I have always had to do this manually).

Typically you would aim them 1/3 up from the bottom. Any higher results in poor performance when travelling at high speed.

Step backwards with the latest IS, the additional wipe is no more :(

The IS series washer jets hit between 10 cm and 40 cm from the bottom of the windscreen when measured in the middle of the screen (not the side jets).

The washer jets are not adjustable. However, jets with different aims are available from Lexus.

85381-30110 is the "normal" direction jet.

85381-3013 is the "high" pointing jet

85381-30150 is the "very high" pointing jet

85381-30140 is the "low" pointing jet"

85381-30160 is the "very low" pointing jet

Very many thanks for the information.

I will measure mine when I get a chance, but I suspect that I have the "low" ones fitted, so may get Lexus to put a pair of "high" jets in at the next service.
