Windshield and rear window/headlight washer fluid (Opel Corsa C)

20. The windshield and rear window/headlight washer fluid is poured into a special reservoir. When the vehicle is equipped with a windshield washer system without a headlight washer function, the reservoir is installed in the left rear corner of the engine compartment between the engine compartment bulkhead and the front wall of the passenger compartment under the air intake grille on the driver's side (see illustration 4.20a). With this configuration, the fluid level is checked visually through the translucent plastic body of the tank or through the filler neck with the cap removed. On models equipped with a washer system with a headlight washer function, the tank is installed in the front part of the engine compartment behind the right headlight. The filler neck cap is located on the upper beam of the front of the engine compartment (see illustration 4.20b).

21. In regions with a moderate climate, clean water can be used as a windshield washer fluid, but do not fill the reservoir more than 2/3 full to compensate for the expansion of water when it freezes during frosts. When operating the car in severe climatic conditions, use only patented windshield wipers that provide an appropriate decrease in the freezing point of the liquid. To avoid freezing of the glass when washing in cold weather, preheat it by blowing air passed through the heater heat exchanger.

Note: The instructions for using the liquid are usually printed on the container label (see also Specifications for this Chapter). Never use antifreeze used in the cooling system to add to the windshield washer fluid - the latter is aggressive towards the paintwork of the body panels!
