Solution
1. Preparation
  • Gather tools: coolant pressure tester, OBD-II scanner, socket set, and safety gloves.
  • Ensure the engine is cool before beginning any work to avoid burns.
2. Coolant Replacement
  1. Drain the Coolant:
    • Place a drain pan under the radiator.
    • Open the drain valve at the bottom of the radiator and allow the coolant to drain completely.
  2. Flush the System:
    • Close the drain valve and fill the radiator with water.
    • Start the engine and let it reach operating temperature while the heater is set to maximum.
    • Turn off the engine, allow it to cool, and drain the water again.
  3. Refill with New Coolant:
    • Mix the new coolant with distilled water according to the manufacturer's specifications.
    • Fill the radiator and reservoir to the recommended levels.
3. Thermostat Replacement (if faulty)
  1. Remove the Thermostat Housing:
    • Disconnect the negative battery terminal.
    • Remove hoses connected to the thermostat housing.
    • Unbolt and remove the thermostat housing.
  2. Replace the Thermostat:
    • Remove the old thermostat and check for proper opening.
    • Install a new thermostat with a new gasket.
    • Reattach the thermostat housing and hoses securely.
4. Water Pump Inspection/Replacement (if necessary)
  1. Inspect the Water Pump:
    • Check for coolant leaks around the water pump shaft.
    • Listen for unusual noises indicating wear.
  2. Replace the Water Pump (if faulty):
    • Disconnect the negative battery terminal.
    • Remove any components blocking access to the water pump.
    • Unbolt the water pump and remove it from the engine.
    • Install the new water pump with a new gasket and torque to manufacturer specifications.
5. Radiator Fan Test/Replacement (if needed)
  1. Test the Radiator Fan:
    • With the engine running, verify the fan activates when the engine reaches higher temperatures.
  2. Replace the Fan (if faulty):
    • Disconnect the battery.
    • Remove the fan assembly by unbolting it from the radiator and disconnecting wiring.
    • Install the new fan assembly and reconnect wiring.
