  • Disconnect the battery to prevent electrical issues.
2. Coolant Level Check and Refill
  • Tools Required: Coolant funnel, new coolant.
  • Instructions:
    1. Open the coolant reservoir and check the level.
    2. If low, add the appropriate type of coolant as specified in the owner’s manual.
    3. Start the engine and let it reach operating temperature, checking for leaks.
3. Thermostat Removal and Replacement
  • Tools Required: Socket set, torque wrench, gasket scraper.
  • Instructions:
    1. Locate the thermostat housing (typically near the engine block).
    2. Remove the bolts securing the housing using a socket.
    3. Carefully remove the housing and thermostat.
    4. Clean the mating surfaces with a gasket scraper.
    5. Install the new thermostat with the correct orientation and replace the housing.
