Windscreen washer nozzles: cleaning, adjustment and replacement
Windscreen washer nozzles ensure a clear view and a quick and easy rinsing of the windscreen. Nevertheless, these nozzles can get dirty and clogged over time and need cleaning and in some cases replacement. We show you how to clean, adjust or replace the nozzles yourself easily, quickly and reliably.
Windscreen washer nozzles: functionality
The windscreen washer nozzles are connected to the car's washer tank. By applying the corresponding lever in the car, the water is sprayed onto the windscreen and wiped away by the windscreen wiper. A cleaning detergent is usually added to the water to more efficiently remove dirt and dust from the windscreen. The spray nozzles do not spread the water, but merely direct it straight onto the windscreen.
Clogged washer nozzle: what now?
When upon applying the lever no water reaches the windscreen, there are several possibilities. To start with, the tank could be empty or the pump could be damaged. If the tank is full and you hear the pump working, the nozzles are probably clogged. A quick remedy is removing minor pollutions from the nozzle with a needle. If the pollution is too severe, removing the nozzle might be the only option. Soak the nozzle in a general descaler for at least an hour. Subsequently clean the nozzle with clear water. If possible, blow it through with pressurised air to remove all lime residue. After the treatment the spray nozzles can be installed and adjusted again.
Correctly adjusting the washer nozzle
Modern windscreen washer nozzles can be easily removed and installed, though adjusting correctly them is another matter. As a rule you need a special tool for this, which can vary depending on supplier. The adjustment is performed under the bonnet and several attempts could be necessary before the water finally hits the windscreen at the right spot. Work with patience and always observe small steps in adjusting the position of the windscreen washer nozzles. This is the best way to attain an optimal result.
When do you need new windscreen washer nozzles?
There are several grounds for new windscreen washer nozzles. Possibly, the nozzles are so calcified and dirty that even thorough cleaning obtains no satisfactory result. In this case, replacement makes sense. Many manufacturers offer windscreen washer nozzles with different profiles, allowing a wider reach of the water jet on the windscreen. If you prefer these fan nozzles, you need to replace the old ones.
Step by step removal and installation of the windscreen washer nozzles
No special tool is required for the replacement of windscreen washer nozzles. This repair can be easily performed without any previous experience.
- Open the bonnet.
- Pull the connection hose from the washer nozzle.
- To do this compress the hose with two fingers right at the nozzle and then pull it off.
- The washer nozzles are held in place by plastic stoppers.
- Compress the stopper with needle pliers and pull it out of the hole in the bonnet.
- Close the bonnet and remove the washer nozzle.
- Installation goes in the reverse order.
- Fill the washer tank.
- Adjust the washer nozzle correctly.
What to observe when replacing spray nozzles
- Take care not to damage the plastic stoppers if the nozzles only need cleaning. Replacing them requires less care.
- Do not kink or damage the hose at installation and removal.
How expensive are new washer nozzles?
Costs for new windscreen spray nozzles are quite moderate and replacement is often the better option. Depending on model and manufacturer washer nozzles cost anything from a few pounds to maximally 30 EUR (± £26). The replacement takes only a few seconds and there is no need for going to a garage for this repair. Only adjusting the washer nozzles might take up a bit more of your time.
