Engine Repair
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 |
