Dorman VVT Solenoid 917-010 — Direct-Replacement OEM-Fit for GM, Isuzu, Hummer Vehicles

The Dorman 917-010 is a direct-replacement variable valve timing (VVT) solenoid engineered to restore proper VVT operation for compatible GM, Isuzu, Hummer, Saab and Oldsmobile vehicles.

This replacement VVT solenoid is built to match the fit and function of the original component, using durable materials and vehicle-level testing to help ensure long-term reliability. It’s intended for applications where the factory VVT unit shows signs of wear, electrical failure, or oil passage blockage. Before ordering, verify compatibility by entering your vehicle details in the garage tool and confirming the fitment indicator.

How does this VVT solenoid affect engine performance?

A functioning VVT solenoid controls oil flow to the cam phasers that adjust valve timing; when it operates correctly, timing advances or retards as the engine demands. Replacing a faulty solenoid can restore smoother idle, improved throttle response, and steadier idling during load changes. It does not alter engine specifications but returns the timing control to intended behavior.

• Regulates oil to cam phasers for correct timing adjustments
• Helps reduce erratic idle and hesitation under load
• Designed to match original-fit electrical and mounting interfaces

Will the Dorman 917-010 fit my vehicle?

This unit is specified for many GM and related models across early-2000s through early-2010s model years. Compatibility includes Buick, Chevrolet, GMC, Hummer, Isuzu, Oldsmobile and Saab applications listed in the product details. Always confirm fitment using the site’s garage tool and check for any special fit notes shown by the fitment icon.

• Fits multiple models: Chevrolet Colorado, Trailblazer, Buick Rainier, GMC Canyon/Envoy, Hummer H3/H3T, Isuzu lines, Saab 9-7x, Oldsmobile Bravada
• Model years vary by application — verify with vehicle entry tool
• Look for blue "i" fitment icon for additional verification notes

What are the key quality and durability features?

Dorman builds this solenoid using quality materials intended to resist wear and oil contamination over time, and subjects the part to on-vehicle testing to confirm fit and functionality. The design aims to replicate the original part’s mechanical interface and electrical connection so installation is straightforward for experienced DIYers or professional technicians.

• Constructed from durable materials to resist degradation
• On-vehicle testing helps verify fit and performance characteristics
• Engineered to match OEM mounting points and electrical connectors

How difficult is installation and what should I check?

Installation complexity is moderate: access to the VVT solenoid location varies by engine and may require removal of intake or engine covers. Basic hand tools and a safe (engine-cool) work environment are typically sufficient; replacing the solenoid also provides a good opportunity to check oil condition and wiring harness connections. If you’re unsure, a professional mechanic can complete the swap quickly.

• May require intake or cover removal depending on vehicle
• Check oil condition and wiring connector integrity during replacement
• Recommended for technicians or experienced DIYers comfortable with engine access

Who is this part for? The Dorman 917-010 VVT solenoid is aimed at owners and technicians working on the specific GM, Isuzu, Saab and Hummer models listed in the product application who need a reliable, direct-fit replacement for a failing or unreliable factory VVT unit. It’s suitable for drivers wanting to restore proper valve timing control without costly engine overhauls, and for repair shops stocking common replacement components for early-2000s to early-2010s American and related vehicles.
