AULINK VVT Camshaft Position Actuator Solenoid Pair (Intake & Exhaust) for GM 2.0L–2.4L — Direct-Fit, OEM Cross-Reference, Premium

These two AULINK VVT camshaft position actuator solenoids (intake and exhaust) replace OE numbers 12655420/12655421 to restore variable valve timing control on compatible GM 2.0L–2.4L engines.

If your Chevy, GMC, Buick, Pontiac or Saturn with a 2.0L–2.4L L4 engine is showing VVT fault codes, rough idle, or oil leaks at the solenoid, this pair (intake + exhaust) provides a direct-fit replacement engineered to meet OEM fit and function. Manufactured in TS16949 certified facilities, the set includes premium O-rings and is backed by a one-year or 50,000 km warranty to help ensure reliable operation and long service life.

How do these solenoids affect engine performance?

VVT solenoids control oil flow to the cam phasers, allowing timing adjustments that optimize torque, fuel economy and emissions. A failing solenoid can cause sluggish throttle response, misfires or a check-engine light related to camshaft timing.

• Restores correct oil routing to cam phasers for accurate timing
• Helps reduce rough idle and improves throttle response
• Addresses common VVT fault codes tied to timing circuit issues
