1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool and disconnect the battery.
Gather safety equipment, including gloves and goggles.

2. Coolant Level and Hoses Inspection

Sub-steps:
- Open the hood and locate the coolant reservoir.
- Check the coolant level; if low, add the appropriate coolant mixture.
- Inspect all hoses connected to the radiator and engine for leaks or damage. Replace any damaged hoses.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, gasket scraper.
Sub-steps:
- Locate the thermostat housing and remove the bolts using a socket wrench.
- Carefully remove the thermostat and inspect for proper movement.
- Clean the mating surfaces on the engine and housing with a gasket scraper.
- Install the new thermostat ensuring it is oriented correctly, then reattach the housing and torque to manufacturer's specifications (typically around 15-20 lb-ft).

4. Water Pump Inspection/Replacement

Tools Required: Socket set, pliers, coolant catch pan.
Sub-steps:
- Drain the coolant from the system into the catch pan.
- Locate the water pump and check for leaks or unusual noises.
- If defective, remove the water pump by disconnecting hoses and bolts.
- Install the new water pump, ensuring all connections are secure and torque to specifications.

5. Radiator and Fan Check

Sub-steps:
