AULINK VVT Oil Control Solenoid Kit 4-Pack for GM 2.8L/3.0L/3.6L – Direct-Fit, Premium O-Rings

AULINK 4-piece oil control VVT solenoid kit (OEM 12586722 and cross-references) is a direct-fit replacement set designed to restore variable valve timing oil control for numerous GM and related 2.8L, 3.0L and 3.6L engines.

These four VVT (variable valve timing) oil control solenoids regulate engine oil flow to the timing system, helping maintain proper valve phasing. Built in TS16949-certified facilities and fitted with premium O-rings, this kit replaces worn or leaking OE units used across Buick, Cadillac, Chevrolet, GMC, Pontiac, Saab, Saturn and select Suzuki applications. It ships as a matched set to help you service all banks and banks' positions in one job—especially useful when replacing multiple aging solenoids at once.

Which vehicles and engines will these solenoids fit?

The kit lists multiple OEM numbers (including 12586722, 12588943, 12615613 and others) and fits a wide range of GM platforms. Compatible cars include Buick LaCrosse, Enclave, Rendezvous, Cadillac ATS, CTS, SRX, XTS, Chevrolet Equinox, Malibu, Traverse, Impala and Camaro, GMC Acadia and Terrain, plus select Pontiac, Saab, Saturn and Suzuki V6 models.

• Designed for 2.8L, 3.0L and 3.6L V6 engines across GM brands and allied models.
• Cross-references OEM part numbers listed in product features for accurate matching.
• Suitable for many model years from roughly 2004–2020 depending on model.
• Intended as direct-fit replacements; check vehicle VIN and part cross-reference before ordering.

How do these solenoids improve engine oil control and VVT performance?

These solenoids modulate oil pressure to variable valve timing actuators to enable correct cam phasing. Properly functioning units reduce the risk of timing instability caused by oil leakage or blocked passages and help the VVT system respond predictably across different rpm ranges.

• Premium O-rings reduce oil leaks and preserve oil pressure integrity.
• Precision valving ensures consistent oil metering to cam phasers.
• Manufactured to meet or exceed OE function for reliable control under engine operating conditions.

What should I expect during installation and maintenance?

Installation is generally straightforward for a technician or experienced DIYer with access to basic hand tools and vehicle-specific procedures. Replace all four units if several show wear; cleaning oil passages and using fresh engine oil during reassembly helps prolong service life.

• Replace as a set when multiple solenoids show symptoms (rough idle, timing codes, oil leaks).
• Follow OEM torque specs and connector inspection guidelines during installation.
• Flush or change engine oil if contaminated oil caused solenoid sticking; use manufacturer-recommended oil grade.

What warranty and quality assurances come with this kit?

AULINK backs these solenoids with a limited warranty to provide buyer confidence while covering manufacturing defects. Production in TS16949-certified facilities and 100% functional testing are part of the product's quality controls.

• 1-year or 50,000 km warranty for manufacturing faults.
• Produced and inspected under automotive-quality standards (TS16949).
• Each unit tested to meet or exceed original equipment function prior to shipping.

Who is this for: This four-piece AULINK VVT solenoid kit is aimed at owners and mechanics working on GM-derived V6 engines who need a cost-effective, direct-fit replacement for failing oil control valves. It suits owners performing routine engine timing maintenance, shops replacing multiple solenoids at once, and anyone restoring VVT responsiveness in 2.8L, 3.0L or 3.6L equipped models. Always confirm vehicle compatibility with OEM cross-references and your VIN before purchase to ensure a correct fit.
