Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant recovery container, OBD-II scanner.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Coolant Level and Condition Check

Remove the coolant reservoir cap.
Inspect the coolant level; if low, top off with the manufacturer-recommended coolant mixture (typically a 50/50 mix of coolant and water).
If coolant is dirty or contaminated, proceed to replace it.

3. Thermostat Replacement (if faulty)

Locate the thermostat housing (usually at the engine block).
Remove the bolts securing the thermostat housing using a socket set.
Remove the old thermostat and replace it with a new one, ensuring proper orientation.
Reinstall the thermostat housing and torque the bolts to the manufacturer specifications (typically around 10-15 ft-lbs).

4. Water Pump Inspection and Replacement (if necessary)

Remove any components obstructing access to the water pump (e.g., serpentine belt, engine covers).
Inspect the water pump for leaks or faulty operation (check for play in the shaft).
If the pump is defective, unbolt it from the engine block and replace it with a new pump.
Reinstall any components removed and ensure correct alignment of the serpentine belt.

5. Radiator Inspection and Repair

Check the radiator for any visible leaks or blockages in the fins.
If leaks are present, replace the radiator with a new unit.
Ensure all hoses connected to the radiator are secure and replace any damaged hoses.

6. Cooling Fan Operation Check

Inspect the electrical connections and fuses for the cooling fan.
If the fan does not engage, test the fan motor with a multimeter for continuity.
Replace the fan motor if it is defective.
