2005 Mercury Sable Heater Core Parts Questions & Experts Answers

• Q: How to service and repair the heater core on 2005 Mercury Sable?

  A: A heater core service or repair must start with conducting a pressure leak test for suspected leakages. Start by removing the instrument panel after which you should proceed with the right-side cowl vent screen removal. Take out the screws then the water shield before clamping off heater hoses and disconnecting them. Vehicle owners should take out the Remote Climate Control (RCC) module by first disconnecting its electrical connector then removing the two nuts along with disconnecting the vacuum harness followed by removing the two screws. All vehicles need continued steps that include removing screws and shield before disconnecting the temperature blend door actuator electrical connector while taking out the actuator and its screws. First detach the temperature blend door assist spring then gently remove the supplemental temperature blend lever shaft by depressing its tab to break free from the supplemental blend door before rotating off the supplemental blend door pivot shaft from its metal link. Begin by detaching the metal link from the temperature blend door pivot shaft before you remove the heat core cover by unscrewing it while rotating the pivot shaft and then removing the cover and its attached seal. You must extract the heater core after rotating the blend door pivot shaft from its place. Reverse the installation steps while lubricating coolant hoses with plain water if needed before refilling the cooling system.
