Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting the repair.
Disconnect the negative battery terminal for safety.

2. Coolant Level Check and Replacement

Sub-steps:
1. Remove the coolant reservoir cap.
2. If the coolant is low, add a 50/50 mix of antifreeze and distilled water to the recommended level.
3. Replace the cap securely.

3. Replace Engine Coolant Temperature Sensor

Tools Required: Socket set, wrench set, screwdriver, new engine coolant temperature sensor.
Sub-steps:
1. Locate the engine coolant temperature sensor (refer to the service manual for exact location).
2. Disconnect the electrical connector from the sensor.
3. Use the appropriate socket to remove the sensor from the engine block.
4. Install the new engine coolant temperature sensor and torque it to the manufacturer’s specifications.
5. Reconnect the electrical connector.

4. Thermostat Inspection and Replacement

Tools Required: Socket set, gasket scraper, new thermostat and gasket.
Sub-steps:
1. Drain the coolant from the radiator into a clean container.
2. Remove the thermostat housing bolts and take off the housing.
3. Remove the old thermostat and clean the mating surfaces with a gasket scraper.
4. Install the new thermostat (ensure the spring side faces the engine) and new gasket.
5. Reattach the thermostat housing and torque the bolts to the specified torque.

5. Radiator Fan Check

Sub-steps:
1. Turn on the ignition without starting the engine.
2. Activate the radiator fan by powering it directly to ensure it operates correctly.
3. If the fan does not operate, replace the fan motor.
