But the worn Toyota A/C evaporator core parts need to be repaired or replaced after a long time. The Toyota A/C evaporator core is part of the air conditioning system that absorbs heat. The evaporator core is usually placed near the blower fan. The removal process for the evaporator core parts is as follows. Drain some coolant from the cooling system to avoid a mess first. Then remove mounting screws from under the hood (if applicable). Next, remove the dashboard for easier access and remove the evaporator core box from under the dash. Finally, carefully pull the evaporator core out so the coolant inside will not leak. Our website has premium Toyota A/C evaporator core parts and devices.
