Nissan Sentra Service Manual: Cooling fan
Component
- Fan shroud and motor assembly
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.
NOTE:
- When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
- Replace the fan shroud and motor assembly as a unit. Do not replace cooling fan motor or cooling fan blade separately.
