Hlola ithangi lokupholisa elikhanyayo ngenkathi injini iphola. Uma izinga loketshezi lihlala phakathi kwemigqa yokumaka ethi "F" kanye "L" yethangi lokugcina, lihlangabezana nezidingo. Uma izinga loketshezi liku-"L" noma lingaphansi komugqa, isipholile sidinga ukungezwa ukwenza ileveli yoketshezi ifinyelele kulayini "F". Ngemva kokwengeza isipholile, uma izinga lokupholisa lehla esikhathini esifushane, kungase kubonise ukuvuza. Kuyadingeka ukuthi uhlole ngeso lengqondo irediyetha, amapayipi, isivalo sokupholisa injini, irediyetha kanye nevalvu yokudonsa amanzi, kanye nephampu yamanzi ukuze ubone ukuthi awekho yini amanzi aphumayo. Uma kungekho kuvuza okutholakele, imoto idinga ukushayelwa iyiswe esiteshini esiqokiwe ukuze ihlolwe futhi. Kumele kuqashelwe ukuthi ukuvimbela ukusha, ungasikhiphi i-radiator cap lapho injini isashisa.
