1. Mavavu a RADIATORthupi limayikidwa pakhomo la radiator.Mukayika, chonde tcherani khutu ku kayendetsedwe ka madzi kuti agwirizane ndi momwe muvi wasonyezera;

2. Pofuna kuthandizira kuyika kwa thermostat, chogwiriracho chiyenera kukhazikitsidwa pamalo apamwamba kwambiri (malo a nambala 5) musanayambe kuyika, ndipo mtedza wotsekedwa wa thermostat uyenera kugwedezeka pa thupi la valve;

3. Pofuna kupewa kulephera kugwira ntchito chifukwa cha kuwotcherera slag ndi zinyalala zina, mapaipi ndi radiator ziyenera kutsukidwa bwino;

4. Pokonzanso makina otenthetsera akale, fyuluta iyenera kuikidwa kutsogolo kwa radiator thermostatic valve;

5. Thermostat valve valve iyenera kuikidwa bwino kuti thermostat ikhale yopingasa;

6. Pofuna kuonetsetsa kuti kutentha kwa mkati kumakhala kolondola, valavu ya thermostatic sichikhoza kuikidwa mu mpweya.Pochigwiritsa ntchito, chiyenera kutetezedwa ku dzuwa lolunjika ndipo sichikhoza kutsekedwa ndi zinthu zina.
