A-Premium VVT Intake Exhaust Camshaft Position Actuator Solenoid Valve Kit
Best for broad GM Ecotec applications. This kit includes both intake and exhaust solenoids, with fitment for Chevrolet Equinox, HHR, Impala, Malibu, Cobalt, Captiva Sport, Orlando, GMC Terrain, Buick LaCrosse, Regal, Verano, Pontiac G5/G6/Solstice, Saturn Saab lines, and more. The reference numbers cover a wide range of factory solenoids, simplifying replacement when multiple units are involved. Useful for vehicles transitioning to OEM-style PWM oil control and improving idle stability and timing control.
Who it’s for: Owners of GM vehicles with Ecotec engines seeking a single, comprehensive replacement for both VVT solenoids. Why selected: broad compatibility reduces the need to mix parts and helps restore accurate cam timing.
Caution: Verify exact solenoid part numbers and engine size before purchase to ensure compatibility with your model year and engine code.
A-Premium 2-PC Engine Variable Valve Timing (VVT) Solenoid
Best for Ford and related V8 applications needing targeted valve timing control. This two-solenoid set is designed for engines like the Ford F-150 (3.5L and 4.6L variants), Expedition, Mustang, Lincoln Mark LT, Navigator, and Mercury Mountaineer. It supports multiple VVT functions to adjust camshaft timing for varied RPM ranges, supporting improved efficiency and response.
Who it’s for: Ford/Mercury/Lincoln owners with 4.6L or similar VVT engines. Why selected: a dedicated two-piece kit captures the common VVT failure points without needing a dual-brand solution.
Caution: Confirm your exact engine family and VVT control module compatibility, as Ford/Lincoln/Mercury VVT solenoids vary by model year and specification.
AULINK Intake & Exhaust Camshaft Position Actuator VVT Solenoid
Best for a wide 2.0L to 2.5L GM fitment range. This OEM-number replacement covers multiple Buick, Cadillac, Chevy, and GMC vehicles, including Regal, ATS, Malibu, Impala, Colorado, Acadia, Canyon, Envision, and more. It emphasizes TS16949-certified facilities for quality, and it’s designed to restore proper PWM oil-flow to the cam phaser.
Who it’s for: GM owners seeking a robust, factory-matched substitute. Why selected: explicit OEM reference numbers and broad coverage reduce guessing about compatibility.
Caution: The breadth of fitment can require precise model verification to ensure the correct solenoid aligns with your vehicle, engine, and year.
Dorman 916-520 Variable Valve Timing Solenoid
Best for professional aftermarket replacements. Dorman’s 916-520 VVT solenoid aims to match the function and performance of the stock part for selected applications. The product line emphasizes durability and the company’s long history in automotive parts, making it a common choice for independent repair outlets and DIY enthusiasts seeking reliability.
Who it’s for: Vehicle owners needing a straightforward, durable replacement that aligns with OEM expectations. Why selected: established manufacturer with a long-standing track record in automotive parts.
Caution: Specific vehicle applications vary; verify exact fitment to avoid incorrect installation on non-target engines.
2-Pack VVT Solenoid 12655420
Best for Ecotec engines with the 12655420 intake and 12655421 exhaust references. This two-pack is designed for GM 2.0L/2.2L/2.4L Ecotec variants, spanning models such as Cobalt, HHR, Malibu, Equinox, Impala, Captiva, Orlando, and more. It is positioned as a PWM-capable option to restore proper cam timing and reduce common VVT faults.
Who it’s for: GM Ecotec owners targeting a complete two-solver replacement. Why selected: explicit coverage for common intake and exhaust solenoids in a single package.
Caution: Check the exact engine code to ensure the 2-pack includes the correct solenoids for your configuration; PWM compatibility may vary by ECU tuning.
Buying Guide
- Compatibility matters: Start with your engine family and model year. Solenoids vary by engine code (for example, GM Ecotec vs. Ford 4.6L/5.4L lines).
- Intake vs. exhaust: Some kits include both solenoids; others are sold as a pair for a single function. Decide if you need one or both sides replaced.
- OEM references: OEM numbers in product descriptions help verify fitment more precisely than generic claims.
- Quality and durability: Look for parts manufactured to TS16949 standards or established brands with a long history of automotive replacements.
- Ease of installation: Some solenoids use standard 2-pin plugs and common connectors; check your vehicle’s connector style before purchasing.
- Symptoms indicating replacement: Rough idle, misfires related to cam timing, check engine light with P0010/P0011/P0013/P0014 codes, and poor fuel economy can all signal VVT solenoid issues.
FAQ
- What does a Variable Valve Timing Solenoid do?
– It controls the oil flow that positions the camshaft, improving engine efficiency and performance across RPM ranges. - How do I know if my car needs a VVT solenoid replacement?
– Symptoms include rough idle, hesitation, reduced fuel economy, and check engine light with cam timing-related codes. - Can I replace just the intake or exhaust solenoid?
– Yes, some engines benefit from replacing only the affected side, but many kits include both to restore full VVT function. - Are OEM-number parts better than aftermarket?
– OEM-number parts help ensure exact fit, but reputable aftermarket solenoids can offer reliable performance at a lower cost. - Will a replacement solenoid fix sludge-related stalls?
– If sludge has blocked oil flow, replacing the solenoid can help, but cleaning the oil passages and addressing lubrication is important for long-term reliability.
