How to service and repair the heater core on Toyota Corolla?

The heater core repair process starts with cooling unit removal and draining the engine coolant from the radiator while only draining part of the coolant. Your first step must be disconnecting the water hoses connected to the heater radiator pipes through the use of pliers which will allow you to maneuver the hose clip claw along the hose before removing it from the pipes. The instrument panel and reinforcement should be removed first followed by the rear heater ducts during this process. You must slide the floor carpet backward to detach each duct. The heater unit removal begins with disconnecting the wire harness clamp followed by nut removal from three points. Start by installing the heater unit with its 3 nuts then restoring the wire harness clamp. Install the rear heater ducts first, then connect water hoses to the heater radiator by placing the hose onto the pipe until reaching the second ridge before applying the hose clip correctly. Engine coolant needs to be filled before reattaching the cooling unit.

The Toyota Corolla Heater Core is a part of the climate control system of the car and operates in much the same way as a car radiator by taking extra heat from the engine and circulating it into the car's interior. Constructed of aluminum or brass with fins to enlarge the surface area, the core carries a sixty/forty water and antifreeze mixture near the engine. The system may have features such as valves or doors that are used to control the temperature with the higher end models having dual climate setting to optimize the users comfort in the house. With regard to the air-conditioned vehicles, the heater core plays another role of dehumidification by reheating cooled air. Problems such as blockage, dripping, and rust are experienced and most of the times, the dashboard has to be disassembled in a bid to effect repairs.
