Piv nrog rau cov kav dej tsis sib haum, kev teeb tsa kev nrawm nrawm dua. Khoov cov yeeb nkab kom yooj yim ntawm lub ces kaum. Muab cov coils ntev txog 100 ko taw ntev, tso cai rau lub sijhawm ua haujlwm ntev dua thiab kev sib txuas tsawg dua, thaum txo tus nqi, sijhawm, thiab cov ntsiab lus xau. Cov yeeb nkab antifreeze yuav nthuav me ntsis thaum khov thiab cog lus thaum lub sij hawm thawing. Nws muaj feem xyuam rau kev faib dej txias thiab kub, kev tiv thaiv hluav taws thiab cov kav dej hauv nroog.
