Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Coolant Replacement

Tools Required: Coolant siphon or drain pan, funnel, and safety goggles.
Sub-steps:
1. Locate the drain valve on the radiator and open it to allow old coolant to drain into a container.
2. Close the drain valve once all the coolant has been drained.
3. Use a funnel to fill the radiator with the appropriate type of coolant (refer to the owner's manual for specifications).
4. Fill the coolant reservoir to the recommended level.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, gasket scraper, new thermostat, and gasket.
Sub-steps:
1. Locate the thermostat housing, typically found near the engine block.
2. Remove the housing bolts using a socket set and carefully detach the housing.
3. Remove the old thermostat and clean the mating surfaces with a gasket scraper.
4. Install the new thermostat, ensuring the alignment is correct.
5. Reattach the housing and torque bolts to the manufacturer’s specifications.

4. Radiator Fan Inspection/Replacement

Tools Required: Multimeter, socket set, and replacement fan (if needed).
Sub-steps:
1. Connect a multimeter to the fan connector to test for voltage when the engine is hot.
2. If the fan does not operate, remove it using a socket set and disconnect the wiring harness.
3. Install the new fan by reversing the removal steps and secure it in place.
