Gates VVS252 Engine Variable Valve Timing (VVT) Solenoid - Exhaust (Left)

OE-Style VVT Solenoid for Subaru Exhaust Timing

The Gates VVS252 engine variable valve timing solenoid is built to OE specifications for fit, form, and performance. It is designed for Subaru applications that use an exhaust-side oil control valve, helping restore proper cam timing response and engine operation.

Gates Engine Variable Valve Timing Solenoids are part of a focused OE performance line for precise oil control and dependable operation. This VVS252 unit uses durable materials and an electromagnetic activation style to support consistent valve timing control in the applications listed below.

• OE-spec fit, form, and performance
• Electromagnetic activation style
• 12-volt design
• 1 female connector with 2 male blade terminals
• Seal and gasket included
• Steel shaft construction
• Overall length: 4.843 in. (123 mm)
• Overall width and height: 1.118 in. (28.4 mm)
• Shaft diameter: 0.709 in. (18 mm)

Detailed Description

The Gates VVS252 variable valve timing solenoid, also referred to as an oil control valve, regulates oil flow to the VVT system so the engine can adjust cam timing as commanded. This OE-style replacement is engineered for direct replacement in Subaru exhaust-left applications, including 2010 Subaru Legacy, 2010 Subaru Outback, 2010 Subaru Tribeca built May 23, 2010 and older, plus 2008-2009 Subaru Tribeca. If you are searching for a Subaru Legacy exhaust VVT solenoid or a Subaru Outback exhaust oil control valve, VVS252 is the correct part number to compare.

This part cross-references Dorman OE Solutions 916-921 for the same application. It also cross-references Standard Ignition VVT171 for the same application.

What It Helps Address

• Rough or unstable idle caused by incorrect cam timing control
• Reduced engine response from a sticking or failing VVT solenoid
• Check engine light conditions related to variable valve timing operation
• Loss of fuel economy from improper oil control to the cam phaser system
• Emissions concerns tied to inconsistent valve timing

Installation Notes and Tips

Verify the exhaust-left position and model year before ordering, especially on 2010 Subaru Legacy, Outback, and Tribeca applications with the May 23, 2010 cutoff. Inspect the connector, terminals, and sealing surface before installation, and replace any damaged gasket or oil residue contamination at the mounting area. Confirm the electrical connector is a female 1-port style with 2 blade terminals and match the shaft dimensions to the original unit.

Quality Assurance

Gates designs this Engine Variable Valve Timing Solenoid to OE specifications and tests it to help restore engine performance, fuel economy, idle quality, power delivery, and emissions control in the listed Subaru applications.
