- Male pin terminal design with 2 pins
- Single connector configuration for straightforward electrical matching
- Engine variable valve timing solenoid replacement from Cloyes
Detailed Description
The Cloyes VTS129 variable valve timing solenoid is intended for vehicles that use an electronically controlled VVT system and need replacement of a failed solenoid. Its compact body measures 5.709 inches long and 2.175 inches wide, with a 0.943-inch shaft diameter, helping it match the original service envelope on the listed fitments. This part number, VTS129, applies across a broad range of GM and related platforms including Chevrolet Colorado, GMC Canyon, and Chevrolet Trailblazer applications.
Cloyes positions this engine VVT solenoid as a repair solution for higher-mileage vehicles where timing control issues can affect drivability and engine performance. The part number VTS129 should be matched to the vehicle’s original connector and electrical specification before installation.
What It Helps Solve
- Erratic valve timing control
- Check engine light concerns related to VVT operation
- Rough idle caused by a failing solenoid
- Loss of engine response from a malfunctioning timing actuator
- Replacement needs on higher-mileage engines
Installation Notes
Verify connector style, pin count, and electrical specification against the original unit before installation. Confirm fitment by year, make, and model for Chevrolet Colorado, GMC Canyon, Hummer H3, and the other listed applications. Professional installation is recommended when diagnosing VVT-related engine concerns.
Quality Assurance
Cloyes manufactures engine timing components and related control parts for service replacement applications. This part cross-references Monroe Shocks & Struts (e.g., 12615873, 8126158730) for the same application.
