Solution

1. Preparation

Gather Tools: OBD-II scanner, coolant pressure tester, socket set, thermometer, multimeter, and safety gloves.
Safety Precautions: Disconnect the battery before starting work on the vehicle. Allow the engine to cool completely before opening the coolant system.

2. Addressing Coolant Leaks

Locate the Leak: Use a coolant pressure tester to identify the source of any leaks.
Replace Damaged Hoses: If any hoses are found to be cracked or leaking, replace them with OEM parts. Tighten hose clamps to manufacturer specifications.
Seal Minor Leaks: For minor leaks in the radiator, apply a suitable sealant as per manufacturer instructions.

3. Thermostat Replacement

Remove Thermostat: Drain coolant to a safe level, remove the thermostat housing, and take out the old thermostat.
Install New Thermostat: Place a new thermostat in the housing, ensuring proper orientation. Reinstall the housing and tighten bolts to the specified torque.
Refill Coolant: Refill the coolant system with the appropriate type and mixture of coolant as recommended by the manufacturer.

4. Cooling Fan Inspection/Replacement

Test Fan Operation: Turn on the vehicle and monitor the cooling fans. If they do not activate, test the fan motor with a multimeter.
Replace Cooling Fan: If the fan is faulty, disconnect the battery, remove the fan assembly, and install a new cooling fan. Reconnect all wiring and test its operation.

5. Water Pump Replacement

Remove Water Pump: Drain the coolant completely, disconnect hoses, and remove the bolts securing the water pump.
Install New Water Pump: Clean the mounting surface, position the new pump, and tighten bolts to the specified torque. Reconnect hoses and refill the coolant.
