Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Allow the engine to cool completely before starting the repair.

2. Replace Coolant

Sub-steps:
1. Drain the coolant from the radiator by opening the drain valve.
2. Close the drain valve and refill the system with new coolant according to the manufacturer’s specifications.
3. Run the engine with the radiator cap off to let air escape, topping off as necessary.

3. Replace Thermostat

Sub-steps:
1. Locate the thermostat housing, typically near the engine block.
2. Remove the hoses connected to the thermostat housing.
3. Unscrew the thermostat housing bolts using a socket set.
4. Remove the old thermostat and clean the mating surfaces.
5. Install the new thermostat with the correct orientation and secure the housing.

4. Inspect and Replace Cooling Fan

Sub-steps:
1. Disconnect the electrical connector to the cooling fan.
2. Remove any bolts or screws securing the fan assembly to the radiator.
3. Take out the fan assembly and inspect for damage or wear.
4. Install the new fan assembly and reconnect the electrical connector.

5. Verify Water Pump Functionality

Sub-steps:
1. Locate the water pump, typically at the front of the engine.
2. Look for any leaks or signs of wear (such as a loose belt).
3. If malfunctioning, remove the water pump by disconnecting the belt and unbolting it.
4. Install a new water pump and reattach the belt, ensuring proper tension.
