Solution

1. Preparation

• Tools Required: OBD-II scanner, coolant pressure tester, multimeter, socket set, torque wrench.
• Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.
• Disconnect the battery to prevent electrical accidents.

2. Refill Coolant

• Sub-steps:
  1. Locate the coolant reservoir for the battery cooling system.
  2. Remove the cap and check the coolant level.

  3. Remove the mounting bolts using a socket set and lift out the old fan assembly.
  4. Install the new cooling fan assembly, securing it with bolts and reconnecting the electrical connectors.

4. Inspect and Repair Cooling System

• Sub-steps:
  1. Use a coolant pressure tester to check for leaks in the system.
  2. If leaks are detected, replace damaged hoses or fittings.
  3. If the radiator is damaged, remove it using the socket set and replace it with a new one.
  4. Ensure all connections are tight and secure to prevent future leaks.

5. Reconnect Battery and Test
