Heater Core

A heater-core repair service starts with disconnecting the battery ground cable followed by draining the cooling system. Start by raising and supporting the vehicle before removing the heater hoses connected to the heater core as well as the vacuum line connected to the engine. You should start by lowering the car and then remove the floor console. Take the Air Bag Diagnostic Monitor out before placing it to the side. Unfasten the vacuum supply line both from the vacuum reservoir tank and the air distributor which evolves from the heater/evaporator core housing. The removal process of the heater outlet floor duct requires screwing off the duct then sliding the air duct upward while freeing both side retaining tabs. Start by detaching the heater core cover and core through four retaining clip removal. When reinstalling the components follow the removal steps while testing the heating and air conditioning system for regular function. A vehicle may exhibit abnormal drive symptoms after switching the battery due to it relearning its adaptive strategy that needs a minimum drive of 16 km (10 mi) for completion.

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.

Starting heater core service requires disconnecting the battery ground cable followed by cooling system draining. First position the vehicle on raises followed by hose disconnection of the heater core from both heater hoses and vacuum line separation from the engine. The procedure calls for heater core drain-out. Start by lowering the vehicle and remove the floor console before detaching the air bag diagnostic monitor that needs placement to an adjacent side. The vacuum supply line and the air distributor need detachment from the vacuum reservoir tank and heater/evaporator core housing. Disassembly of the heater outlet floor duct begins by unscrewing it while sliding the air duct upward until releasing its retaining tabs on both sides. The De-ice sensor electrical connector needs removal before the heater core cover and core can be taken out by detaching four retaining clips. Withdraw the De-ice sensor through cable removal and unfastening its clip. Reverse the removal steps then refill the cooling system after which check all heating and air conditioning functions for proper operation.

Detach the seal and release the three retaining tabs, then separate the housing by releasing the five retaining tabs and pulling off the clip.

Pull out the cable and unclipping it.
