Checking windshield washer system

Checking the windshield washer system includes reviewing the washer fluid levels, the condition of the washer system, and the quality of the windshield washer. Driving with a dirty windshield poses a risk to all road users. Therefore, the washing system is an important safety system and should always be ready for operation.

The washing system consists of a washing liquid, a liquid tank, a washing pump, hoses, nozzles, and a wiper system with blades.

A tank of washing liquid is usually located under the hood of a vehicle. For some vehicles that have a rear window washer, the fluid reservoir may be separate and located in the rear of the vehicle or the boot. See the information system or manual to locate the tank and the filler cap.

The windshield washer fluid should be checked whenever the engine oil is changed and each time the vehicle is serviced. Driving in dusty or humid conditions may require more frequent inspections. It is important to use the correct windshield washer fluid. In winter, a liquid that protects against freezing is used.

Never use laundry or dishwashing detergent as the chemicals in the detergent may damage the vehicle.

The electric pump in the tank pushes the pressure washer fluid through the hose to the sprayer which sprays and diverts it to the windshield. By checking the washing system, we assess the condition of the sprayer and its position.

If the sprayer is clogged or a weak jet of liquid comes out of it, it is necessary to clean it. The sprayers are easy to remove to perform cleaning. They can be blown with a pneumatic blower or cleaned with special needles. When the sprayer cannot be cleaned, it is replaced with a new one.

In case the sprayer does not redirect the liquid correctly on the windshield, then its positioning is performed. There is a special telescopic tool for this adjustment that makes it easier for us to direct the jet of washing liquid.

The wipers together with the washing fluid application system help the driver to see clearly in front of the vehicle in all driving conditions. Defective wiper blades make it difficult to wash the windshield. Inspections of vehicles often show that the wipers are missing, damaged, or worn.

Wiper blades should be checked as part of external control. The wiper blades and wiper arms should be checked. If the vehicle is not garaged, due to the constant external influence, the wiper blades will be ready for replacement after only one year. The wiper blade should be flexible and not frayed. The wiper arm should bend at the hinges, hold firmly and push the wiper blade against the windshield. The wiper blade and wiper handle are checked with one examination of the hand.

Never use wipers when they are dry as this may damage blades or scratch the windshield surface. Never bend the handles to make the blades fit better on the glass. The handles are tensioned by the manufacturer and you can only damage them. If you find that the lever has lost thrust, replace it.
