Help keep cool air coming from the vents with the Spectra Premium ac condenser, part number 7-4789. It is a direct-fit replacement for many vehicles, among them the 1997-2000 Chevrolet Venture, 1997-2000 Oldsmobile Silhouette and 1999-2000 Pontiac Montana. See the "Vehicles it fits" section for the full list and engine-specific details.
The A/C condenser is where the air conditioning system sheds heat. Hot, high-pressure refrigerant passes through its tubes and fins, releases heat to the air flowing across it, and condenses into a liquid before continuing through the system.
- Reverse engineered for fit: Spectra Premium reverse engineers its A/C condensers so they fit properly at installation.
- OEM construction style: Supplied in the same construction style as the original equipment unit.
- Quality materials: Manufactured with what Spectra Premium describes as the highest quality materials.
- Specialty testing: Testing focuses on leak-free operation and on reduced movement and vibration.
Signs a condenser may need replacing include warm or weak airflow from the A/C vents, cooling that fades at idle or in traffic, refrigerant or oil residue on the core, and bent, blocked, or corroded fins. Other A/C components can cause similar symptoms, so diagnose the system before you replace the condenser.
Replacing a condenser opens the refrigerant circuit. The refrigerant must be recovered first, and the system must then be evacuated and recharged with proper equipment. Follow the vehicle service information for related components and procedures.
