How to remove the fan of Hummer H2?
1 Answers
Below is the method for removing the fan of Hummer H2: 1. First, remove the fan protective casing. 2. Then, loosen the surrounding fixing screws. 3. After disconnecting the power supply wires and sensor wires connected to the engine, water temperature gauge, and air conditioning, the fan can be removed. Additional information: The electric fan only operates to reduce the temperature of the radiator. The radiator temperature is influenced by two factors: one is the cooling of the engine block and transmission, and the other is the heat dissipation of the air conditioning condenser. The air conditioning condenser and the radiator are two separate components, placed closely together, with the condenser in front and the radiator behind. The air conditioning is a relatively independent system within the vehicle. However, the activation of the air conditioning switch sends a signal to the electronic fan control unit J293, forcing the electronic fan to rotate.
