What is Heater Core Replacement?

The heater core serves as a small radiator that receives hot coolant from the engine. As the engine's water pump circulates coolant from the main radiator, a portion of it is directed into the heater core. With the blower fan in operation, the heater core adds heat to the cabin, providing temperatures up to 85°F to 100°F above outside temperatures.

How is Heater Core Replacement Done?

  1. Disconnect the vehicle battery and remove the steering wheel.
  2. Remove outer doors, kick panel casings, fuse box covers, and speakers.
  3. Remove accessories such as gauges, radio, speakers, and glove box.
  4. Detach the air conditioner control panel.
  5. Unbolt and carefully remove the car dashboard.
  6. Identify and disconnect the heater hoses.
  7. Shift air ducts and components away from the heater casing.

  9. Take out the old heater core and install the replacement, securing it with fasteners.
  10. Reassemble all components and accessories in reverse order.

Recommendations

In addition to compromised functionality, a leaking heater core can lead to coolant damage and pose health risks due to its toxicity. Ethylene glycol, methanol, and propylene glycol, present in coolant, can cause serious symptoms if ingested. Prompt replacement is crucial to prevent further damage and ensure a comfortable driving experience.
