I have been losing the fluid out of the washer fluid container. I fill the container to the top, and after driving to work and back, the fluid level has gone down below where I can see it.

I have replaced, with new, the container, and the 2 rubber gaskets for the pump and the level sensor.

Any ideas? Rubber hoses at the pump, or the level sensor?

 

You've already replaced anything attributed to a leaky washer fluid container...Unless your commute is from east coast to west, you must
have something visible....thats a huge leak ?

 

From full to this level in 2 days, and no sign of fluid on the garage floor. Unless I could drive around with the wheel liner off, I'm not seeing any sign of leakage.

 

It is a long shot, but I'll mention what happened to me. I found that under hard braking (not sure how hard is hard enough to cause this) the fluid would be thrown forward and splash out of the top even with the cover on. One time, it actually pushed the cover open so I zip tied it closed. Any chance this could be the issue?

 

Is it leaking in the rear trunk, and filling tool/jack area?

 

Could be splashing into the engine bay under hard braking. If that cap pops off. When mine leaked on the bottom from the pump it was on the garage floor.

Make sure the line is not leaking into the trunk near the rear wiper motor.

 

Thank you for your input.

Would a new blue cap possibly help? Original is 11 years old. Fluid loss shown is after 2 days, and washers have not been used in that time. I have deliberately not used the washers to try and eliminate any of the hoses after the pump as being the issue.
