Out of the blue my sensor read "low windshield fluid" the other day. I filled it up with a whole bottle of windshield fluid and the message went away.

I then noticed that fluid was leaking out the drivers side bottom of my car. After a few minutes the message came back so I figured I just lost the whole bottle to a leak. Not sure how I developed a leak because the vehicle has never been in an accident.

I opened the hood and removed the engine covers. I verified that the bottom of the funnel tube that you pour the fluid into was firmly attached to the top of the reservoir.

My next step will be to remove the bumper to inspect the reservoir. However, before I go through that hassle I wanted to know if anyone has experienced this before or if any of the experts can let know what they think the problem is.

Also, does anyone have the part number for the reservoir? I tried looking on Sewells but could not find it.

Thanks!

Thanks! Are these the same part numbers for a 2007 IS350? Link is for 2011 IS250.

 

Before going to the trouble of removing the entire bumper, you MIGHT be able to figure out what is up by removing the driver's side front wheel and taking a peak behind the wheel liner. Guessing it might be leaking from where the "pump" attaches to the bottle; but you don't know, it could be a slight cut to the feed line.

GL!

 

Thanks... I think I'll try that first since I will have to take my winters off in a couple weeks anyways. Good suggestion.
