Solution

1. Preparation

Gather necessary tools and replacement parts.
Ensure the engine is cold before starting the work to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Coolant

Tools Required: Coolant funnel, drain pan.
Sub-steps:
1. Place the drain pan under the radiator.
2. Open the radiator drain valve and allow old coolant to drain completely.
3. Close the drain valve and refill the radiator with the manufacturer-specified coolant.
4. Run the engine with the radiator cap off to allow air bubbles to escape, then replace the cap.

3. Thermostat Replacement

Tools Required: Socket set, new thermostat, gasket.
Sub-steps:
1. Locate the thermostat housing and remove the bolts using a socket set.
2. Carefully lift the thermostat out of the housing.
3. Clean the mating surfaces to ensure a proper seal for the new gasket.
4. Install the new thermostat and gasket, and reattach the housing.

4. Radiator Fan Inspection and Testing

Tools Required: Multimeter, basic hand tools.
Sub-steps:
1. Locate the radiator fan connectors and disconnect them.
2. Use a multimeter to test for power at the connector while the engine is running.
3. If there is no power, check the relay and fuses associated with the cooling fans.
4. If the fans are faulty, replace them with new units.

5. Water Pump Inspection and Replacement

Tools Required: Socket set, new water pump, gasket, coolant.
Sub-steps:
1. Drain the coolant again and remove any components obstructing access to the water pump.
2. Remove the water pump mounting bolts and carefully take out the old pump.
3. Clean the mounting surface and install the new water pump with a new gasket.
4. Reassemble any components removed and refill the coolant.
