Paipi ya radiator ya injini kwa nthawi yayitali idzakhala yokalamba, yosavuta kusweka, madzi ndi osavuta kulowa mu radiator, payipi imasweka pamene ikuyendetsa, kutuluka kwa madzi otentha kwambiri kudzapanga gulu lalikulu la kutuluka kwa nthunzi ya madzi kuchokera ku chivundikiro cha injini, pamene izi zikuchitika, muyenera kusankha nthawi yomweyo malo otetezeka oti muyime, kenako tengani njira zadzidzidzi kuti muthetse vutoli.
Kawirikawiri, pamene radiator ili m'madzi, cholumikizira cha payipi ndicho chimayambitsa ming'alu ndi kutuluka madzi. Panthawiyi, mutha kudula gawo lowonongeka ndi lumo, kenako kulowetsa payipi mu cholumikizira cholowera cha radiator kachiwiri, ndikuchilimbitsa ndi chogwirira kapena waya. Ngati ming'alu ili pakati pa payipi, mutha kukulunga ming'alu yotuluka ndi tepi. Pukutani payipi musanayikulunge, ndikukulunga tepi mozungulira kutuluka madzi atauma. Chifukwa mphamvu ya madzi mu payipi imakhala yokwera injini ikugwira ntchito, tepiyo iyenera kukulungidwa mwamphamvu momwe mungathere. Ngati mulibe tepi, mutha kukulunganso pepala la pulasitiki mozungulira kung'ambikako, kenako kudula nsalu yakaleyo m'zidutswa ndikuzikulunga mozungulira payipi. Nthawi zina ming'alu ya payipi imakhala yayikulu, ndipo ikhoza kutayikirabe ikangolowa. Panthawiyi, chivundikiro cha thanki chikhoza kutsegulidwa kuti muchepetse kuthamanga kwa madzi ndikuchepetsa kutuluka madzi.
Pambuyo poti njira zomwe zili pamwambapa zatengedwa, liwiro la injini siliyenera kukhala lachangu kwambiri, ndipo ndikofunikira kuyika kuyendetsa bwino kwambiri momwe mungathere. Mukamayendetsa, ndikofunikiranso kulabadira malo owunikira kutentha kwa madzi. Kutentha kwa madzi kukakwera kwambiri, ndikofunikira kuyimitsa ndikuziziritsa kapena kuwonjezera madzi ozizira.
Radiator imagawidwa m'njira zitatu zoyikira, monga mbali imodzi mkati, mbali imodzi kunja, mbali yosiyana mkati, mbali yosiyana kunja, ndi pansi mkati ndi pansi kunja. Kaya njira iti ingagwiritsidwe ntchito, tiyenera kuyesetsa kuchepetsa kuchuluka kwa zolumikizira mapaipi. Zolumikizira mapaipi zikachuluka, mtengo wake sudzangowonjezeka, komanso zoopsa zobisika zidzawonjezeka.
