Walker 590-1399 Engine Variable Valve Timing (VVT) Solenoid
Walker 590-1399 VVT Solenoid Overview
Walker 590-1399 is an OE replacement engine variable valve timing solenoid built to restore camshaft control in modern GM applications. It regulates pressurized oil flow to the cam phaser or VVT sprocket, helping maintain proper valve timing across changing engine loads and speeds.
Compatible with 2019-2021 Chevrolet Silverado 1500, 2020-2021 Chevrolet Silverado 2500 HD, 2020-2021 Chevrolet Silverado 3500 HD, and other listed Cadillac, Chevrolet, and GMC applications, this part number 590-1399 is a direct-fit service solution for timing-related drivability concerns.
Key Features
- OE replacement VVT solenoid for dynamic camshaft timing control
- Heat-resistant plastic housing for engine-bay durability
- Precision-machined internal valve for controlled oil flow
- Oil-sealed connector design for reliable electrical connection
- Exact OE fit for factory wiring and mounting points
- Black connector with D-shaped, female connector design
- 2-terminal, pin-style electrical interface
- 3 mounting holes for secure installation
Detailed Description
Walker Products 590-1399 is engineered to meet or exceed OE specifications for electrical response, oil flow control, and pressure regulation. The solenoid’s job is to direct engine oil to the cam phaser so valve timing can adjust in real time, improving throttle response, fuel efficiency, and emissions performance under varying driving conditions. This makes it a practical replacement for vehicles such as the Chevrolet Corvette, GMC Sierra 1500, and Cadillac Escalade when the original unit is no longer operating correctly.
Built with a 70.00 mm housing width and a 4.00 mm shaft diameter, this VVT solenoid is designed for consistent fit and function in supported GM platforms. Walker 590-1399 is a direct OE-style service part for technicians and owners addressing timing control faults on 2019-2021 Chevrolet Silverado 1500 and related applications.
Common Issues This Part Can Address
- Check engine light with VVT-related fault codes such as P0010-P0014 or P0020-P0024
- Rough idle or unstable engine speed
- Hesitation during acceleration
- Reduced engine power or sluggish throttle response
- Timing control problems caused by a sticking or electrically failed solenoid
Installation Notes and Tips
Install Walker 590-1399 using the factory connector and mounting points on the applicable engine. Before replacement, inspect the oil condition and verify that the VVT passages are not restricted, since contamination can affect solenoid operation. Confirm the vehicle application by year, make, and model before service.
Part number 590-1399 is listed for 2021 Cadillac Escalade and Escalade ESV, 2020-2021 Chevrolet Corvette, 2019-2021 Chevrolet Express 2500 and Express 3500, 2019-2021 Chevrolet Silverado 1500, 2020-2021 Chevrolet Silverado 2500 HD and Silverado 3500 HD, 2021 Chevrolet Tahoe, 2019-2021 GMC Savana 2500 and Savana 3500, 2019-2021 GMC Sierra 1500, 2020-2021 GMC Sierra 2500 HD and Sierra 3500 HD, and 2021 GMC Yukon and Yukon XL.
Quality Assurance
