Izithuthi zamafutha esintu zisebenzisa inkunkuma yobushushu be-injini ukufudumeza isisipholisi, kwaye zithumela ubushushu besipholisi kwikhabhin ngezifudumezi kunye namanye amacandelo ukunyusa ubushushu ngaphakathi kwikhabhin.Ekubeni i-motor yombane ayinayo i-injini, ayikwazi ukusebenzisa isisombululo somoya wemoto yendabuko yamafutha.Ngoko ke, kuyimfuneko ukwamkela ezinye iindlela zokufudumeza ukulungisa ubushushu bomoya, ukufuma kunye nesantya sokuhamba emotweni ebusika.Okwangoku, izithuthi zombane ikakhulu zamkela inkqubo yokufudumeza yombane eyi-air conditioning, oko kukuthi,i-air conditioner eyodwa (AC), kunye ne-thermistor yangaphandle (PTC) yokufudumala i-heater encedisayo.Kukho amacebo amabini aphambili, enye kukusebenzisaIsifudumezi somoya se-PTC, enye isebenzisaI-PTC yokufudumeza amanzi.
