Engine Intake Exhaust Camshaft Position Actuator Solenoid 4Pcs

In this review the focus is on a 4-piece set of engine intake and exhaust camshaft position actuator solenoids designed to address variable timing issues across a wide range of GM vehicles. The bottom line: this kit is aimed at DIY mechanics and independent shops that need an affordable replacement for failed VVT oil control valves; the single biggest reason to buy is value for money combined with compatibility, since the parts reference common OE numbers and cover many models from 2004 through 2017, making it a practical repair option for owners dealing with timing-related fault codes.

Key Features

• OE Reference Compatibility: Matches several OE ref numbers such as 12586722 and 12588943 so it fits many GM V6 and V8 engines that use these oil control valves.
• Wide Vehicle Coverage: Fits Cadillac, Chevrolet, GMC, Buick, Pontiac and Saturn models from the mid 2000s through 2017, reducing the need to buy multiple different parts for fleet repairs.
• Four-Piece Kit: Includes intake and exhaust solenoids for both banks, allowing a full timing actuator service in a single purchase for engines that require four valves.
• VVT Oil Control Valve Design: Intended as a direct replacement for variable valve timing systems, helping restore proper cam timing and address related OBD codes.
• Economical Replacement: Positioned as a value option that several customers report fixed their error codes without the higher cost of OEM units.

Who It's For

This set is best for owners of compatible GM vehicles who are comfortable working on engine valve covers and electrical connectors and who want an economical way to resolve VVT fault codes or rough running due to stuck actuators. It is also useful for small repair shops that service multiple GM makes and need a common part that fits several models.

Those who should look elsewhere include drivers who require dealer OEM branding or verified factory warranty coverage, and anyone who cannot perform or arrange a proper installation and testing process, because correct fitment and electrical connection are essential for proper function.
