HVAC & 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 may include:

  • Lack of or insufficient cooling in cabin

Compressor:

The compressor compresses refrigerant. The compression leads to a change in the refrigerant’s boiling point, which helps create the cold air that is delivered through the HVAC system.

Signs of wear may include:

  • 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 may include:

  • Engine overheating
  • Leaking coolant

Condenser:

The condenser cools refrigerant gas back into a liquid state.

Sign of wear may include:

  • Reduced cooling capacity in vehicle cabin due to physical damage or debris

Compressor Clutch:

A critical component of your HVAC system, the compressor clutch engages and disengages your compressor.

Signs of wear may include:

  • Reduced cooling in vehicle interior
  • Noise when running A/C system
  • Rubbing/grinding noise when A/C is off

Blower Motor:

Your vehicle’s blower motor drives air through the HVAC system and into your cabin.

Signs of wear may include:

  • Lack of or diminished airflow through cabin vents
  • Unusual noises coming from blower motor

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 may include:

  • Engine overheats
  • Fan doesn’t turn on
  • Poor A/C performance

Expansion Valve:

The 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 may include:

  • 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 may include:
