Detailed Product Overview

This Gates VVT solenoid regulates oil flow to the cam phaser system so the engine computer can adjust valve timing as needed. Accurate timing control supports smoother idle, stronger throttle response, improved fuel economy, and lower emissions when the original solenoid is worn, sticking, or electrically failing. Part number VVS310 is listed for 1998-2002 Ford Escort, 2002 Ford Focus, 1999-2002 Mercury Cougar, 1998-2000 Ford Contour, and 1998-2000 Mercury Mystique.

This part cross-references Dorman OE Solutions 918-054 for the same application.

Common Problems This Part Can Address

• Rough or unstable idle caused by inconsistent cam timing control
• Reduced engine response from delayed variable valve timing operation
• Check engine light conditions related to VVT solenoid performance
• Lower fuel economy from improper oil control valve operation
• Increased emissions from timing control faults

Installation Notes and Tips

Verify connector style, terminal count, and mounting dimensions before installation. VVS310 uses a single female connector, 2 male blade terminals, and measures 4.6 in. long, 1.16 in. wide, and 4.91 in. high. Inspect the engine oil condition and related passages during service, since contamination can affect solenoid operation. Confirm the vehicle application by year, make, and model before ordering.
