Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is cool to avoid burns.
• Disconnect the negative battery terminal for safety.

2. Coolant Check and Replacement

• Tools Required: Coolant catch pan, funnel, socket set
• Remove the radiator cap (if cool) and check coolant level.
• If low, drain the old coolant using the petcock at the radiator's bottom.
• Refill with the manufacturer's specified coolant, ensuring a proper 50/50 mix with distilled water.

3. Thermostat Replacement

• Tools Required: Socket set, gasket scraper, new thermostat, torque wrench
• Remove the thermostat housing by loosening the bolts; inspect the old thermostat for wear.
• Clean the mating surfaces of the housing and engine block.
• Install the new thermostat ensuring the correct orientation; torque to manufacturer specifications.

4. Radiator and Hose Inspection

• Tools Required: Visual inspection
• Inspect all hoses for cracks or leaks and replace any that are damaged.
• Remove debris from the front of the radiator using compressed air or a soft brush to ensure proper airflow.

5. Cooling Fan Operation Check

• Tools Required: Multimeter
• Reconnect the battery and turn the engine on.
• After the engine reaches operating temperature, check if the cooling fan(s) engage. If not, test the fan motor and relay for function.
