*StarLord, if you can't install back both parts, kahit yung thermo-switch lang muna maibalik mo. Thermo-switch is a sensor to your cooling system which automatically turn off/on the fan motor of your radiator in a certain temperature. Running at high speed in an expressway or highways, with thermo-switch, your fan motors will not turn on due to malamig pa coolant mo dahil napapalamig ng hangin sa pagtakbo mo. Without thermo-switch, napapalamig na ng hangin sa bilis ng takbo mo, andar ng andar pa rin fan motor para sa radiator. Dyan ka madalas magpapalit ng fan motor at relays.
