why is my Honda Accord 8th Generation (2008-2012) overheating after 10 minutes

Solution

1. Preparation

• Tools Required: Socket set, screwdriver set, coolant pressure tester, OBD-II scanner, thermometer.
• Allow the engine to cool completely before beginning any work to prevent burns.

2. Coolant System Inspection

• Flush the Cooling System:
  1. Drain the old coolant from the radiator using a drain pan.
  2. Flush the radiator with clean water to remove debris and old coolant.
  3. Refill with a 50/50 mixture of distilled water and appropriate coolant type (Honda Type 2 or equivalent).

3. Replace Thermostat (if faulty)

• Remove Thermostat:
  1. Disconnect the negative battery terminal.
  2. Drain the coolant again as necessary.
  3. Remove the upper radiator hose and the thermostat housing bolts.
  4. Remove the old thermostat and gasket.
• Install New Thermostat:
  1. Place the new thermostat with the correct orientation.
  2. Install a new gasket and reattach the thermostat housing and upper hose.
  3. Refill the cooling system with coolant.

4. Inspect and Replace Water Pump (if necessary)

• Remove Water Pump:
  1. Disconnect the negative battery terminal.
  2. Drain the coolant.
  3. Remove the drive belt by releasing tension from the tensioner.
  4. Unbolt and remove the water pump from the engine block.
• Install New Water Pump:
  1. Clean the mounting surface on the engine.
  2. Install the new water pump with a new gasket.
  3. Reattach the drive belt and refill the coolant.

5. Test Cooling Fans

• Check Fan Operation:
  1. Turn on the engine and let it reach operating temperature.
  2. Verify that the cooling fans engage when the temperature gauge indicates high temperature.
