The present invention relates to an apparatus for preventing the thermal shock of a hybrid vehicle and a method thereof. When a driving mode of a hybrid vehicle, which adopts a mechanical water pump and an oil pump driving method, is converted from a NON-EV mode into an EV mode, the mechanical water pump and the oil pump are driven, similar to the driving of a motor water pump and a motor oil pump by using a motor driving method. Therefore, competitiveness regarding prime cost may be secured in comparison with a motor driving method system, an engine is protected from thermal impact, and damage to the oil film on a turbocharger shaft may be prevented. The apparatus for preventing the thermal shock of a hybrid vehicle, which includes a motor and an engine as a power source, according to an embodiment of the present invention comprises: a cooling water temperature sensor detecting the temperature of the cooling water of a hybrid vehicle; an oil temperature sensor detecting the temperature ...
