Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Socket set, screwdriver set, coolant pressure tester, OBD-II scanner, thermometer.
Parts Required: Coolant, thermostat (if faulty), hoses (if damaged), water pump (if defective).
Safety Warnings: Allow the engine to cool completely before starting any work to prevent burns.

2. Coolant Replacement

Step 1: Drain the old coolant by removing the drain plug at the bottom of the radiator. Collect the coolant in a suitable container.
Step 2: Flush the cooling system with water to remove any debris or old coolant residues.
Step 3: Refill with the manufacturer's recommended coolant type, ensuring to mix it properly if necessary.

3. Thermostat Replacement

Step 1: Remove the thermostat housing by loosening the bolts with a socket set.
Step 2: Take out the old thermostat and compare it with the new one for correct fitment.
Step 3: Install the new thermostat in the same orientation as the old one, and replace the housing, tightening the bolts to the manufacturer's specified torque.

4. Water Pump Inspection/Replacement

Step 1: If the water pump is suspected to be faulty, remove the serpentine belt.
Step 2: Unbolt the water pump from its mounting and carefully remove it.
Step 3: Clean the mounting surface and install the new water pump, ensuring to tighten bolts to the specified torque.

5. Radiator and Hose Replacement (if necessary)

Step 1: If the radiator is blocked or damaged, remove the radiator by disconnecting hoses and unbolting it from its mounts.
Step 2: Install the new radiator, reconnect hoses, and secure it in place.
Step 3: Replace any damaged hoses to ensure proper coolant flow.
