Kwenzeka ntoni xa itanki iphelelwa ngamanzi kangangeekhilomitha ezingama-20?
Itanki yamanzi ayinamanzi kwaye iikhilomitha ezingama-20 ezivulekileyo ziya kubangela umonakalo omkhulu emotweni, ngokubanzi kwimo yemoto ebandayo, itanki yemoto ayinamanzi inokuqhubeka iqhuba iikhilomitha ezimbini okanye ezintathu, ngaphezulu kweekhilomitha ezintathu kunokonakalisa injini yemoto, okubangela ukuba imoto ingachithi kakuhle ubushushu, ukunyuka kobushushu bamanzi. Itanki yamanzi yemoto yeyona ndawo iphambili kwinkqubo yokupholisa imoto, itanki yamanzi inokubizwa ngokuba yi-radiator. Kubomi bemihla ngemihla bokuqhuba, nikela ingqalelo kulondolozo lwetanki yamanzi, kunokuthintela ukuguga kwetanki yamanzi. Itanki yamanzi yemoto akufuneki inxibelelane nayo nayiphi na i-asidi, i-alkali kunye nezinye izinto ezirhabaxa, kufuneka kusetyenziswe amanzi athambileyo, amanzi aqinileyo kufuneka athambe ngaphambi kokusetyenziswa, ukuze kuthintelwe ukuvaleka kwetanki yamanzi yemoto. Ukuze kuthintelwe ukugqwala kwetanki yamanzi yemoto, ukhetho lwe-antifreeze kufuneka lukhethe abavelisi abaqhelekileyo ngokuhambelana nemigangatho yesizwe ye-antifreeze yexesha elide. Umsebenzi ophambili wetanki yamanzi yemoto kukukhupha ubushushu. Xa amanzi abandayo efunxa ubushushu kwijakethi yamanzi aze angene kwi-radiator, ubushushu buyanyuka bubuyele kwijakethi yamanzi, kwaye ukujikeleza kwegazi kufezekisa umsebenzi wokulawula ubushushu.
