VVT Solenoids

Variable valve timing solenoids can fail due to low engine oil levels and/or irregularly changed engine oil or filters. For a high-quality replacement, Intermotor® VVT solenoids feature hard anodized components to ensure proper performance and long service life.

Solutions for High-Failure Applications

Every variable valve timing system is slightly different, but there are three general rules to follow to ensure proper performance. First, regularly service the engine oil and filter. Second, use the manufacturer’s required engine oil type. Lastly, service the engine oil and filter after you install new solenoids or sprockets.

A specific application that is known to have high failure rates for VVT solenoids include the Toyota 3.0L and 3.3L. As you can see below, Intermotor has these applications covered.
