AULINK 4-Pack OCV Oil Control Solenoids 12586722 | Fits Chevy, GMC, Buick, Cadillac

Premium OCV Oil Control Solenoids for VVT Systems

Elevate your vehicle’s Variable Valve Timing (VVT) with a 4‑pack of AULINK oil control solenoids. These OEM‑style components are designed to provide precise oil flow to the VVT system, helping to keep timing consistent and responsive across a variety of GM models. This set is crafted to work with multiple OEM numbers and engine families, offering a practical solution for maintenance or repairs without sacrificing reliability.

Rather than a single replacement, this four‑piece kit is built to deliver consistent performance across several years and engine variants. You’ll notice the emphasis on durable seals and accurate flow control, which can help support smooth engine operation and dialed‑in timing under typical driving conditions.

• High‑quality O‑rings and seals designed to minimize oil leaks and maintain steady pressure in the VVT path.
• Precise oil flow control to support stable VVT operation and consistent engine response.
• Manufactured in facilities with TS16949‑level quality processes and tested to meet or exceed OE performance.
• Includes four solenoids, making it a practical option for multi‑vehicle ownership or seasonal maintenance.

Fitment, Quality, and Peace of Mind

• Broad compatibility across Buick, Cadillac, Chevrolet, GMC, Pontiac, Saab, Saturn, and Suzuki lineups that use 2.8L, 3.0L, or 3.6L engines.

While outcomes can vary by vehicle and operating conditions, the parts are positioned to support reliable, long‑term performance when installed according to standard procedures.
