In this video, I show you the exact location of both the Intake and Exhaust VVT Solenoids (also known as Variable Valve Timing actuators or oil control valves) on a 2012-2016 Chevrolet Malibu 2.5L. Finding exactly where these solenoids sit on top of the cylinder head is an essential first step for a quick DIY vehicle repair, saving you time and guesswork before you unbolt any components.
Common symptoms of faulty Intake or Exhaust VVT Solenoids include:
- An active Check Engine Light (CEL) on your dashboard, typically with variable valve timing codes like P0010, P0011, P0013, or P0014.
- A rough, surging engine idle, engine hesitation during acceleration, or a noticeable loss of overall engine power.
- Increased fuel consumption (poor gas mileage) or a distinct knocking/rattling noise from the top of the engine, especially when the oil gets dirty or low.
Safety First: Working on top of the cylinder head requires clean working habits to prevent dirt from entering the engine’s oil passages. Always ensure the engine is completely off and cool, protect your hands and eyes by wearing durable gloves and safety glasses, and stay fully focused and attentive throughout the process.
