It is difficult to remove the nozzle without damaging its retainers. Therefore, we simply pull out the old nozzle with pliers, having first removed the hose that is put on its nipple under the windshield frame. It is more convenient to do this work in the warm season - the soft hose is easier to remove. In winter, before removing (or put on) hose, warm it with your hand.
We install a new nozzle, directing the jet towards the glass. We make sure that both retaining tabs are clicked into place.
Holding the nozzle, we put the supply hose on it from below.
