How Parts Work and Signs of Wear: HVAC and Engine Cooling Parts
|Accumulator/Drier: The accumulator in your vehicle gathers and stores liquid refrigerant until it's converted into a gas refrigerant.||Sign of wear: Lack of or insufficient cooling in cabin|
|Compressor: The compressor compresses refrigerant. The compression leads to a change in the refrigerant's boiling point that helps create the cold air that's delivered through the HVAC system. ||Signs of wear: Lack of or insufficient cooling; excessive clicking sounds or unusual noises during A/C operation|
|Water pump: The water pump is responsible for circulating engine coolant through the radiator and engine system to help maintain optimal engine operating temperatures.||Signs of wear: Engine overheating; leaking coolant|
|Condenser: The condenser cools refrigerant gas back into a liquid state. ||Sign of wear: Reduced cooling capacity in vehicle cabin due to physical damage or debris |
|Blower Motor: Drives air through the HVAC system and into the cabin. ||Signs of wear: Engine overheats; fan doesn't turn; poor A/C performance|
|Compressor clutch: A critical component of your HVAC system, the compressor clutch engages and disengages your compressor.||Signs of wear: Reduced cooling in vehicle interior; noise when running A/C system; rubbing/grinding noise|
|Engine cooling fan: The engine cooling fan, located behind your radiator, draws cool outside air through the condenser and radiator at low-speed operation to cool the engine. ||Signs of wear: Engine overheats; fan doesn't turn; poor A/C performance|
|Expansion Valve: Restricts the flow of refrigerant, allowing it to change from a high-pressure liquid to a low-pressure gas, which provides the cooling effect of A/C.||Sign of wear: Lack of cooling in cabin|
|Evaporator: Warm air from inside your vehicle is delivered to your evaporator. Moisture and heat are then removed from the air and returned to your cabin.||Sign of wear: Lack of cooling in cabin|
|Heater core: Hot engine coolant from the cooling system circulates through the heater core to provide warm air to the passenger compartment.||Signs of wear: Sweet smell coming from vents; insufficient heat from vents; wet carpet on passenger side|
|Radiator: Engine coolant flowing through the radiator is cooled by wind and the radiator fan helping to keep the engine within proper operating temperatures.||Signs of wear: Leaking (often a bright green colour); engine overheats; sweet smell|
|Thermostat: Regulates the temperature of the engine coolant to maintain proper engine operating temperature. ||Signs of wear: Engine overheats; reduced fuel economy; insufficient heat in cabin |
