What product must be added to the water in the windshield washer reservoir in case of low temperatures or risk of frost?

Question

DentroTest · Accepted Answer

When temperatures drop below freezing, pure water turns to ice. If this happens inside the windshield washer system, the ice can expand and crack the reservoir, hoses, or damage the electric pump, in addition to preventing you from cleaning the glass, which affects visibility. Therefore, it is mandatory to add specific antifreeze fluid. The term 'anticoagulant' refers to medicine (blood) and is unrelated to mechanics.
