Wells 3T1065 Engine Variable Valve Timing (VVT) Sprocket

The Wells 3T1065 is a direct-fit replacement Engine Variable Valve Timing (VVT) Sprocket, also known as a VVT actuator or cam phaser. This toothed wheel is mounted on the camshaft and works in conjunction with the VVT solenoid to precisely control valve timing for optimized engine performance.

After the VVT solenoid directs oil pressure to the sprocket, the actuator advances or retards camshaft timing, enabling finer adjustments to the intake and exhaust valves. These adjustments regulate combustible fuel flow and exhaust gas movement in and out of the combustion chamber, helping to reduce emissions and improve fuel economy.

Key Features:

• Engineered and thermal-shock tested to match OE parts in fit, form, and function
• Direct replacement for worn or failed factory VVT sprockets
• Manufactured by Wells Vehicle Electronics, a leading global supplier of advanced vehicle electronics
• Installs on the end of the intake or exhaust camshaft

Common Symptoms of a Failing VVT Sprocket:

• Loud rattling or clattering sounds, especially at cold start
• Hard starting
• Reduced power at higher engine speeds
• Illuminated check engine light

The Wells 3T1065 restores proper variable valve timing operation to bring engine efficiency and performance back to factory specifications.
