Windshield Washer Fluid Loss

Hey guys,

I’m currently running a 2025 and noticed a blue/purple ish color in the snow below the anir dam on the driver side. I thought maybe it was soap from washing it the day before but noticed a tad bit more the following morning.
At this point I ruled out the soap and decided to check under the hood to see if I saw any obvious leaks. No obvious leaks found. What I did find was the cap was resting on the neck.
So, I filled it up and put the cap back on securely. You’d think that would have fixed it but I didn’t. I decided to check the next morning and tada, it went down some again. So basically I added and lost fluid 3 days in a row.
Please keep in mind that, the fluid I added was winter windshield wiper fluid and the temps overnight have been roughly between 4-8 degrees. Any ideas on what’s going on?
Thanks!

 

I can’t so I’ll have to take it in.

I’m assuming the cold weather has nothing to do with it?

 

Update: so they have now replaced both the gasket between the upper and lower reservoir as well as the entire lower reservoir . But unfortunately, the filler neck is still draining. It drained down from a full filler neck to the gasket that separates the upper and lower reservoirs on a 15 min car ride home. Any other suggestions on how to fix this?

 

they keep saying that they don’t know how to fix it

 

they can’t find a leak. Nothing visible

 

Probably hairline crack in filler neck and seepage hard to see. Seen it in first gen Tacoma.

 

Could that still be a possibility after a pressure test? Didn’t see any leak and it shot back out at the opening

 

I'd fill it and wrap paper towels around the neck and take it from there. If that's possible.

 

Please explain this? Is it to try and look for color ion the paper towel?

 

No you're looking for wetting. It's leaking from somewhere ... the motor, hose, container. If you saw blue in snow it's leaking.

 

i saw someone post this from 2015.

 

Still no updates . Could it
Possibly be air pockets?
