1997 Chevrolet Express 2500 Air Conditioning Parts

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.

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.

GM Genuine Parts A/C Orifice Tubes are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These 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. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

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.

Made from HNBR material; Compatible with R12 And R134A; High quality construction; Universal applications

Our Connectors are manufactured from the highest quality materials and designed for long life under extreme conditions.

We develop and produce high-quality roller bearings, spherical bearings, and plain bearings worldwide for a wide range of applications.

GM Genuine Parts A/C Service Valves are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These spring-loaded valves allow service access to the A/C system. The service valves allow the service technician to evacuate and recharge the refrigerant in the A/C system. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Protect your A/C system with our A/C Clutch Cycle Switch. Mounted on the low-pressure side, it continuously monitors refrigerant pressure to detect when levels drop below a safe threshold. In response, it automatically disengages the compressor clutch to prevent damage. Crafted from premium materials to withstand harsh conditions, this switch helps ensure reliable cooling performance and prolongs the life of your compressor.

High quality OE replacement part with all components needed to complete the job

Certified A/C Pro Power Clean and Flush Aerosol Cleaner. Aerosol flush for R134a and R12 auto Refrigerant air conditioning systems. Safely removed old oil and contaminants from the air condistion systems. Includes disposable dispensing hose. Biodegradable and environmentally friendly. Fast drying Pproduct includes installation hose.

This A/C service valve cap is designed to match the fit and function of the original cap on specified applications, and is engineered for reliable performance and durability.

The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Switch monitors system pressures, aiding in proper and efficient control of the compressor, fans and system levels. An improperly functioning A/C Pressure Switch will provide erratic or inaccurate actuation and operation, severely affecting system performance and function. Without reliable and accurate actuation from a properly functioning A/C Pressure Switch, critical components and the system as a whole are left unregulated and unprotected which can lead to excessive wear and tear on critical components and costly system damage.

Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.
