Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool before starting work to avoid burns.
Disconnect the battery to ensure safety.

2. Check and Refill Coolant

Sub-steps:
- Open the coolant reservoir cap.
- Inspect the coolant level; add a 50/50 mixture of antifreeze and distilled water if low.
- Replace the cap securely after refilling.

3. Replace Faulty Thermostat

Tools Required: Socket set, torque wrench, gasket scraper.
Sub-steps:
- Locate the thermostat, typically found in the housing at the engine's coolant outlet.
- Remove the bolts holding the thermostat housing using the socket set.
- Carefully lift the housing and remove the old thermostat.
- Clean the mating surfaces with a gasket scraper.
- Install the new thermostat in the correct orientation.
- Reattach the housing and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Radiator Fan

Tools Required: Multimeter, socket set.
Sub-steps:
- Disconnect the electrical connector from the radiator fan.
- Use a multimeter to check for power at the connector when the engine is hot.
- If no power is detected, check the relay and fuse associated with the fan.
- If the fan is faulty, remove it using the socket set and replace it with a new unit.

5. Check Water Pump Functionality

Sub-steps:
- Inspect the water pump for any leaks or unusual noises.
- If malfunctioning, drain the coolant and remove the water pump.
- Replace with a new water pump and ensure proper sealing.
- Refill the cooling system with coolant.
