NewYall Camshaft Actuator Solenoid 4-Pc Set — Direct-Fit OE-Match Intake/Exhaust VVT

NewYall 4Pcs engine intake/exhaust camshaft position actuator solenoids are a direct-fit replacement kit designed to restore variable valve timing control on compatible GM-family vehicles.

This four-piece solenoid set replaces worn or failing camshaft position actuator valves on a wide range of General Motors platforms, helping the engine control system accurately adjust valve timing. Each valve is manufactured to match OE reference numbers and fitment specs, so installation uses the factory mounting points and electrical connectors. The kit is ideal when multiple solenoids show signs of wear, oil leakage, or responsive delay.

Which vehicles will these NewYall solenoids fit?

These solenoids are made for many GM cars, crossovers and trucks built between roughly 2005 and 2017. Compatibility covers Buick, Cadillac, Chevrolet, GMC, Pontiac and Saturn models that came with variable valve timing (VVT) systems from the factory.

• GMC: Acadia (2007–2016), Acadia Limited (2017), Canyon (2015–2016), Terrain (2010–2017).
• Cadillac: ATS (2013–2017), CTS (2005–2017), SRX (2007–2016), STS (2007–2011), XTS (2013–2017).
• Buick, Chevrolet, Pontiac, Saturn compatibility listed for specific model years — see the OE ref numbers for exact matches.

How do these actuator solenoids affect engine performance?

Camshaft actuator solenoids control oil flow to the variable cam phasers; when they operate correctly the engine optimizes valve timing for different speeds and loads. Replacing faulty solenoids can reduce rough idle, eliminate some check-engine codes, and improve throttle response.

• Restores precise oil control to cam phasers for correct timing adjustments.
• Helps reduce VVT-related fault codes and erratic idle behavior.
• Improves drivability by allowing the ECU to use the intended timing maps.

Are these NewYall parts direct replacements and what OE numbers do they match?

Yes — the kit is manufactured to replace factory solenoids and matches several OE reference numbers used across GM models. Confirm fit by comparing the OE references with the part numbers in your vehicle's service information before ordering.

• OE references include 12586722, 12588943, 12615613, 12626012, 12636175 and TS1013.
• Each solenoid uses factory-style connectors and mounting points for straightforward swap-in installation.
• Sold as a complete set of four to address multiple worn units at once.

What should I know about installation and maintenance?

Installation typically requires standard hand tools and basic mechanical skill; access may vary by engine layout and vehicle. Replace the full set if several solenoids are old, and always use clean engine oil and a fresh filter after installation to reduce contamination risk.

• Install by disconnecting battery, removing intake/plenum as needed, swapping solenoids and reconnecting electrical plugs.
• Inspect electrical connectors and keep O-rings lubed with clean oil during fitment to ensure seal integrity.
• Reset codes and perform a short drive cycle to allow the ECU to relearn timing behavior.

Who is this for: This NewYall 4-piece camshaft position actuator solenoid kit is aimed at DIY mechanics, independent service shops, and fleet technicians maintaining mid-2000s to late-2010s GM vehicles. Choose this kit if multiple VVT solenoids are failing, if you want OE-referenced replacements for a cost-effective repair, or if you prefer changing all actuators at once to prevent repeat labor.
