Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Coolant Flush

Tools Required: Radiator flush kit, hose, bucket.
Sub-steps:
1. Remove the radiator cap slowly to relieve pressure.
2. Drain the coolant into a bucket by opening the drain valve at the bottom of the radiator.
3. Use a radiator flush solution and fill the system with water; run the engine for 10-15 minutes with the heater on.
4. Drain the flush solution and refill with the manufacturer-recommended coolant mixture.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, gasket scraper.
Sub-steps:
1. Remove the thermostat housing by unscrewing the bolts (typically 10-12 Nm).
2. Remove the old thermostat and clean the mating surfaces.
3. Install the new thermostat with the correct orientation (spring side toward the engine).
4. Reattach the thermostat housing and torque it to the specified value.

4. Water Pump Inspection/Replacement

Tools Required: Socket set, screwdrivers, gasket scraper.
Sub-steps:
1. Remove any components obstructing access to the water pump (e.g., belts, hoses).
2. Disconnect the water pump from the engine block and remove it.
3. Inspect for any signs of wear or leaks. Replace if necessary.
4. Install the new water pump, ensuring proper gasket placement, and torque the bolts to the manufacturer's specifications.

5. Cooling Fan Check

Tools Required: Multimeter, wiring diagram.
Sub-steps:
1. Connect the multimeter to the cooling fan connector to check for voltage while the engine is running.
2. If no voltage is present, trace the wiring and check the fan relay.
3. Replace the cooling fan if it is inoperative.
