Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the engine is cool before starting work to prevent burns.
• Disconnect the battery to avoid electrical issues.

2. Replace Thermostat

• Tools Required: Socket set, torque wrench
• Sub-steps:
  1. Locate the thermostat housing (usually near the engine block).
  2. Remove the bolts securing the thermostat housing using a socket.
  3. Carefully lift the housing and remove the old thermostat.
  4. Clean the mating surfaces of the housing and engine block.
  5. Install the new thermostat in the correct orientation.
  6. Reattach the housing and tighten to the manufacturer’s specified torque (typically around 10-12 Nm).

3. Inspect and Replace Radiator

• Tools Required: Socket set, radiator removal tool
• Sub-steps:
  1. Drain the coolant from the radiator by opening the drain valve or removing the lower hose.
  2. Remove any components obstructing the radiator (e.g., front grill, fan shroud).
  3. Disconnect the upper and lower radiator hoses.
  4. Remove the mounting bolts holding the radiator in place.
  5. Carefully lift the radiator out of the vehicle and replace it with a new unit.
  6. Reinstall all components in reverse order and refill the cooling system with the appropriate coolant.

4. Check Water Pump

• Tools Required: Socket set, inspection mirror
