How to Maintain and Fix a Heater Core and What Steps Are Involved for a Mercury Cougar?

Repair and service of the heater core begins with disconnecting the battery ground cable followed by draining the cooling system. After suspending the vehicle position the heater hoses and engine vacuum line apart from the heater core before blowing out the heater core. Remove the floor console after lowering down the vehicle. Detach the air bag diagnostic monitor from its position then connect it to one side before disconnecting the vacuum supply line from the vacuum reservoir tank. To remove the heater outlet floor duct the first step involves disconnecting the air distributor from the heater/evaporator core housing while you remove the screw and slide the air duct upwards before releasing the retaining tabs on each side. You should start by disconnecting the De-ice sensor electrical connector before proceeding to unclip the four retaining clips of the heater core cover and core. Remove the De-ice sensor by unclipping its cable connection. Installation requires the same reverse order of removal steps followed by cooling system refill then testing the heat and air conditioning system for proper performance.

Heater Core found in Mercury Cougar vehicles is used to produce warm air inside cars by using hot Engine Heat. Looking somewhat like a miniature radiator, the core is cooled by a solution of water and antifreeze, and as one of the vehicle fan blows through it, transfer heat to the air in the cabin. Some kinds of heater cores can be applied from aluminum or brass, containing the valves or doors which make the necessary temperatures. In conditioned automobiles the heater core also helps in dehumidification whilst it also acts as a backup to the car engine radiator. However, ordinary problems like blockage and cracking can result to expensive repairs since the fixtures have some intricate design making it hard to get into for repair.
