Solution

1. Preparation

  • Check for signs of leakage (dampness, corrosion).
  • If leaking, proceed to replace the heater core.

• Replace Heater Core:

  • Drain the coolant system.
  • Disconnect the hoses from the heater core.
  • Remove bolts securing the heater core and carefully extract it from the casing.
  • Install the new heater core and secure it with bolts.
  • Reconnect hoses ensuring tight fittings.

3. Check and Replace Hoses

• Inspect and Replace Any Damaged Hoses:
  • Check all coolant hoses for cracks or wear.
  • Replace any damaged hoses using the socket set to loosen connections.

4. Refill Coolant

• Refill the cooling system with the appropriate type of coolant (refer to the owner’s manual).
