Zojambula zokupika ndi mtundu wonyamula, zomwe zimatanthawuza mtundu wa zomwe zimagwiritsidwa ntchito ndi zokonda za radiator yokhazikika.
Mu ukadaulo wamakina, pali mitundu yambiri ya zigawo zambiri, koma pali mitundu ingapo yogwiritsidwa ntchito mu radiator yopangidwa ndi radiator: zokhala ndi ma standar pogwiritsa ntchito mikangano, ndipo osakaniza mitundu iwiri ya mitundu iwiri ya masitepe. M'zaka zaposachedwa, opanga opanga a radiator ayambitsa matekinoloje atsopano azithunzi, monga maginito onyamula maginito, mafunde amagetsi, maginito amatsenga, ndi maphokoso. . Ma radiator wamba okhala ndi mpweya amagwiritsa ntchito mafuta ophatikizika ndi mafuta.
Mawonekedwe opangidwa ndi mafuta ndi ma standeve omwe amagwiritsa ntchito mikangano. Mafuta opangira mafuta amagwiritsidwa ntchito ngati mafuta ndi otsika mtengo. Pogwiritsa koyambirira, phokoso logwiritsira ntchito limatsika ndipo mtengo wopanga nawonso ndi wotsika. Komabe, mtundu uwu wokhala ndi vuto lalikulu kwambiri, ndipo moyo wake wa kutumikira uli kumbuyo kwa mpira. Kuphatikiza apo, ngati mtundu uwu umagwiritsidwa ntchito kwa nthawi yayitali, chifukwa cha zifukwa za chisindikizo zam'madzi za radiator, ndipo mafuta opangira mafuta adzayamba kusungunuka, phokoso limakulirakulira komanso mavuto ena. M'zovuta kwambiri, katswiri wowoneka bwino chifukwa cha kuvala bwino kumabweretsa kugwedezeka kwambiri. Ngati izi zikuwoneka, tsegulani Chisindikizo cha mafuta kuti muchepetse ndikugula wokonda watsopano.
Kunyamula mpira kumasintha mtundu wazomwe zokumba, zomwe zimapangitsa kuti zinthu zikhalepodi pakati pa malo omwe akuwoneka kuti atumikire. Choyipa ndikuti njirayi ili yovuta kwambiri, yomwe imabweretsa kuchuluka kwa mtengo ndi phokoso lalikulu.
