Madzi omwe ali mu thanki yamadzi ya galimoto amawira, choyamba ayenera kuchepetsa liwiro kenako kuyendetsa galimoto kumbali ya msewu, musafulumire kuzimitsa injini, chifukwa kutentha kwa madzi kumakhala kwakukulu kwambiri, kungayambitse piston, khoma lachitsulo, silinda, crankshaft ndi kutentha kwina kumakhala kokwera kwambiri, mafuta amakhala ochepa, kutaya mafuta. Musathire madzi ozizira pa injini mukazizira, zomwe zingayambitse silinda ya injini kuphulika chifukwa cha kuzizira mwadzidzidzi. Mukazizira, valani magolovesi, kenako onjezerani nsalu yonyowa yopindidwa pa chivundikiro cha thanki, tsegulani pang'onopang'ono chivundikiro cha thanki kuti mutsegule mpata wawung'ono, monga nthunzi yamadzi kutuluka pang'onopang'ono, kupanikizika kwa thanki kutsika, kuwonjezera madzi ozizira kapena antifreeze. Kumbukirani kusamala za chitetezo panthawiyi, samalani ndi kutentha.
