2011 GMC Sierra 2500 HD Air Conditioning Parts

Carquest Orifice Tubes are designed to regulate the flow of refrigerant through the air conditioning system to provide optimal cooling to the passenger compartment. Each orifice tube is manufactured to original equipment specifications to perform its function even in the harshest climates. Each part is supplied with the necessary gaskets and o-rings for installation.

ACDelco GM Original Equipment A/C Orifice Tubes, which separate the high and low pressure sides of the air conditioning system, control the flow of low pressure liquid refrigerant into the evaporator. The orifice tube is essentially a calibrated restriction located at the inlet to the evaporator. This causes the necessary pressure drop to allow the liquid refrigerant to evaporate within the evaporator and absorb heat. Since the orifice tube is fixed, the system is regulated by either cycling the compressor clutch or by a variable displacement compressor. This original equipment orifice tube is a GM-recommended replacement for your vehicle’s original components and has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Carquest Hose Assemblies are designed to carry refrigerant in an air conditioning system. They are manufactured to meet or exceed original equipment specifications and are designed to easily fit into the engine compartment.

The Carquest condenser is an integral component of the motor vehicle air conditioning system. This part condenses the refrigerant into a liquid to prepare it for entry into the compressor. The condenser is manufactured according to OEM design specifications to ensure a long life with quality performance. Exact design standards produce a seamless fit into the engine compartment.

The Battery Current Sensor reports the movement of electricity to the body control module to control the vehicles charging system and to report any possible battery drain during a key-off condition.

The Brake Pedal Position sensor is similar to the Stop Light Switch but is a more critical sensor input to the vehicle stability system. The vehicle stability control module requires the exact location of the brake pedal during a vehicle skid so that a controlled brake pressure may be applied to each individual wheel in an attempt to straighten the vehicle position out and back into control.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

This direct replacement ABS wheel speed sensor matches the fit and function of an original equipment sensor. Made of quality materials with factory-style electrical connectors, this sensor has been designed and tested to be durable and reliable.

The temperature of various systems must be reported to the engine control module (ECM) as well as other operating system controllers in the vehicle. Coolant temperature, cabin temperature, exhaust temperature and ambient temperature are just a few systems reported by a temperature sensor. The temperature sensor is fed 5 volts by the systems computer, within the sensor housing will be a thermistor, or dropping resistor whose resistance value will change as the temperature surrounding it changes. Changing resistance in the circuit will change the volt signal at the processor indicating the current operating value.
