Tools Required: Radiator wrench, funnel, coolant container
Sub-steps:
1. Place a coolant container under the radiator drain plug.
2. Open the drain plug and allow the old coolant to drain completely.
3. Close the drain plug securely.

3. Thermostat Replacement

Tools Required: Socket set, gasket scraper, torque wrench
Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the thermostat housing bolts using a socket set.
3. Carefully remove the thermostat and old gasket.
4. Clean the mating surfaces with a gasket scraper.
5. Install the new thermostat and gasket.
6. Torque the housing bolts to the manufacturer’s specifications (usually around 20-25 lb-ft).

4. Radiator Inspection and Repair

Tools Required: Pressure tester, hose clamp pliers
Sub-steps:
1. Use a pressure tester to check for leaks in the radiator.
2. If leaks are found, replace the radiator by disconnecting the hoses and removing the mounting bolts.
3. Install the new radiator and reconnect all hoses securely.

5. Fan Operation Check

Tools Required: Multimeter
