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: TPMS Receiver
- Description 1.FunctionThe TPMS monitors the pressure and temperature of the tires and warns the driver of changes that could potentially influence driving conditions.The cluster warning lamp displays the messages generated from processing the data. The ECU processes the data received from the WE sensor, determines the conditions of the tire, and then sends any necessary warning signals to the driver through the CAN line or hard wire control line.- Replacement and Air Bleeding • Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator. • When pouring engine coolant, be sure to shut the relay box lid and not to let coolant spill on the electrical parts or the paint.
