NewYall Camshaft Actuator Solenoid Kit 4-Piece for GM Vehicles — Intake & Exhaust Replacements, OE-Referenced Fit

NewYall 4-piece camshaft actuator solenoid kit replaces intake and exhaust position actuators for a wide range of GM vehicles, restoring precise cam timing control.

If your check engine light points to camshaft or timing control issues, this NewYall kit supplies four replacement solenoids engineered to match OE references and fit many GMC, Cadillac, Buick, Chevrolet, Pontiac and Saturn models. Each solenoid is designed to replace failed or worn actuators that control oil flow to the variable valve timing system, helping the engine maintain optimized valve timing under different loads and speeds.

How will these solenoids fit my vehicle?

These NewYall actuators are specified to match common OE part numbers and cover many model years across several GM brands. Confirm compatibility by comparing listed vehicles and OE references with your VIN or the part number on your existing solenoid. Fitment covers intake and exhaust locations where the factory used the same style actuator.

• Covers OE refs: 12586722, 12588943, 12615613, 12626012, 12636175, TS1013
• Compatible with GMC, Cadillac, Buick, Chevrolet, Pontiac, Saturn models (2005–2017 ranges)
• Includes four solenoids to replace multiple failed units in one service

What are the practical benefits of replacing these actuators?

Replacing worn or failing camshaft actuator solenoids can eliminate rough idle, poor acceleration, and timing-related diagnostic codes. Fresh solenoids restore the oil control needed for variable valve timing to operate as intended, helping drivability and throttle response without costly internal engine repairs.

• Resolves timing-related trouble codes and limp-home mode triggers
• Improves idle smoothness and low-speed responsiveness
• Prevents potential oil-control issues that affect cam phasing

What should I expect during installation and maintenance?

Installation is a straightforward mechanical task for anyone comfortable with basic engine service: remove the engine cover if present, unplug the electrical connector, unbolt the old solenoid and swap in the NewYall unit. Always inspect seals and the electrical connector for corrosion; replace any damaged gaskets and torque bolts to manufacturer specs.

• Typical tools: ratchet, Torx or hex sockets, torque wrench
• Recommended to check oil condition and level before reassembly
• Replace all four if multiple units are failing or for preventive maintenance

Which symptoms indicate a failing camshaft position actuator solenoid?

Common signs include a persistent check engine light, reduced power or misfires, and unusual engine noises during acceleration. These actuators rely on clean engine oil and intact electrical connections—contamination or wear leads to sticking, erratic timing, and diagnostic trouble codes.

• Illuminated check engine light with cam timing codes
• Rough idle, hesitation, or loss of power under load
• Variable valve timing warning or reduced fuel economy

Who is this for: This NewYall 4-piece actuator solenoid kit is aimed at DIY mechanics, independent shops, and fleet owners who maintain mid-2000s to mid-2010s GM vehicles and need a cost-effective set of intake and exhaust solenoids. If your vehicle matches the listed models or OE references and you’re experiencing timing-related drivability issues, this kit supplies four direct-fit replacements to help restore reliable VVT operation and avoid repeat trips for the same fault.
