This is an HVAC heater core, a vital component of the vehicle's climate control system responsible for heating the cabin air. It circulates hot coolant from the engine through a matrix of fins, transferring heat to the air blown across it by the fan. A leaking or clogged heater core will result in a lack of heat, a musty odor, or visible coolant leaks inside the cabin.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing heater core is a noticeable decrease in cabin heating performance, often accompanied by a persistent sweet odor of coolant. If ignored, leaks can worsen, leading to coolant loss and potential damage to interior components. The risk is a compromised cabin environment and potential damage to the vehicle's electrical systems from coolant exposure.
Thoroughly drain the cooling system before disconnecting heater hoses to minimize coolant spillage. Ensure all new hose clamps are properly positioned and tightened to prevent future leaks.
Inspect and replace heater hoses, thermostat, and water pump if they are old or show signs of degradation, as these are often accessed during heater core replacement.
