1.Disconnect the negative (-) battery terminal.
2.Remove the heater and blower unit from the crash pad after loosening the mounting nuts.(Refer to Heater - "Heater Unit")
3.Remove the heater core cover (A) after loosening the mounting screws.
4.Pull out the heater core (A) from the heater unit.
5.To install, reverse the removal procedure.
• If you're installing a new heater core, add refrigerant oil (PAG OIL).
• Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-1234yf to avoid leakage.
• Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
• Do not spill the refrigerant oil on the vehicle ; it may damage the paint, if the refrigerant oil contacts the paint, wash it off immediately.
• Apply sealant to the grommets.
• Make sure that there is no air leakage.
• Charge the system and test its performance.
• Do not interchange the inlet and outlet heater hoses and install the hose clamps securely.

Hyundai Accent (HC) (2017 - 2022) Service Manual: Engine Oil
- Replacement • Prolonged and repeated contact with mineral oil will result in the removal of natural fats from the skin, leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause skin cancer. • Exercise caution in order to minimize the length and frequency of contact of your skin to used oil.Hyundai Accent (HC) (2017 - 2022) Service Manual: Auto Defoging Actuator
- Components Location 1. Auto logging actuator - Description The auto defogging sensor is installed on front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives a signal from the sensor and restrains moisture and eliminates defog by the intake actuator, A/C, auto defogging actuator, blower motor rpm and mode actuator.
