Amanzi etankini yamanzi emoto abilayo, kufuneka aqale athobe isantya kwaye emva koko aqhube imoto ecaleni kwendlela, ungangxami ukucima i-injini, kuba ubushushu bamanzi buphezulu kakhulu, kuya kukhokelela kwipiston, udonga lwentsimbi, isilinda, i-crankshaft kunye nolunye ubushushu buphezulu kakhulu, i-oyile iyabhitya, ilahlekelwe kukuthambisa. Musa ukugalela amanzi abandayo kwi-injini xa upholisa, nto leyo enokubangela ukuba umbhobho we-injini ugqabhuke ngenxa yokuphola ngesiquphe. Emva kokupholisa, nxiba iiglavu, uze wongeze iqhekeza lelaphu elimanzi elisongiweyo kwikhuselo letanki, khulula ngobunono isigqubuthelo setanki ukuvula isithuba esincinci, esifana nomphunga wamanzi ngokucothayo ukhuphe, uxinzelelo lwetanki phantsi, yongeza amanzi apholileyo okanye isinqanda-kuqhwala. Khumbula ukuba ubeke ingqalelo kukhuseleko ngexesha le nkqubo, qaphela ukutshisa.
