Sack13 Posted January 23, 2017 Share Posted January 23, 2017 Greetings all. I have an issue when filling my windscreen washer tank, when filling it runs and drips down onto the frontside tire, losing some of the fluid (around 50%) in the process. The water pump has been changed recently, and the issue was occurring before this, so I can only assume there is a leak or crack in the piping which feeds the tank. How can I go about diagnosing/repairing this? Thanks in advance, Sam Quote Link to comment Share on other sites More sharing options...
Sack13 Posted January 29, 2017 Author Share Posted January 29, 2017 For anyone interested, or having a similar issue, this is how I diagnosed and fixed the problem. First of all I removed the windscreen cowl and plastic cover next to the washer fluid cap. After this I removed the filler tube itself, plugged it with kitchen roll and poured water into it. No leaks appeared here, but there was a small cracking along the natural plastic seal, so I used a sealant mixture just in case..  Quote Link to comment Share on other sites More sharing options...
Sack13 Posted January 29, 2017 Author Share Posted January 29, 2017 Following this, I jacked up the car and removed the wheel arch liner, this granted access to the screen wash reservoir tank. With the filler cap attached, I tested again by pouring in some water, however the leak was still present. I went ahead and detached the water pump and disconnected the electrical inputs, allowing me to remove the entire reservoir. Examining and testing the tank with the same methods as before, I could find no issues or cracks. However, after firmly attaching the filler cap/tube to the seal of the reservoir, no leaks occurred, I came to the conclusion that it was simply the connection between the filler cap/tube and the screen wash reservoir that wasn't strong or sufficient enough. So, quite simply, I cleaned the reservoir and reattached to the wheel arch. I then firmly pushed the filler cap into the seal of the reservoir and screwed back into position, lo and behold!! No more leakage! I tested the washers to make sure I had made all electrical connections again correctly and all was good. Problem solved! In conclusion, if you have this issue, test that the seal between the filler cap/tube is tight first and go from there! This will save you a lot of time and hassle removing the wheel arch and the entire tank! I hope this helps anyone who has the same leak! 2 Quote Link to comment Share on other sites More sharing options...
