Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery for safety.

2. Coolant Inspection and Replacement

Tools Required: Coolant container, funnel, socket set, torque wrench
Sub-steps:
1. Open the hood and locate the coolant reservoir.
2. Check the coolant level; if low, inspect for leaks in hoses and connections.
3. If leaks are found, replace the damaged hoses or connections.
4. Drain the old coolant into the container and dispose of it properly.
5. Refill the system with manufacturer-recommended coolant, ensuring the correct mixture.

3. Thermostat Replacement

Tools Required: Socket set, gasket scraper, new thermostat, gasket sealant
Sub-steps:
1. Locate the thermostat housing, usually connected to the upper radiator hose.
2. Remove the bolts securing the thermostat housing and gently detach it.
3. Remove the old thermostat and clean the mating surfaces with a gasket scraper.
4. Install the new thermostat with the correct orientation (usually marked).
5. Reattach the thermostat housing and torque the bolts to the manufacturer's specifications.

4. Radiator and Water Pump Assessment

Tools Required: Pressure tester, multimeter
Sub-steps:
1. Inspect the radiator for any physical damage or external blockages.
2. Use a pressure tester to check for leaks in the radiator and hoses.
3. If the water pump is suspected to be faulty, check for leaks around the pump and listen for unusual noises.
4. If necessary, remove the water pump and install a new one, ensuring all gaskets are replaced.
