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, Standard and Intermotor VVT solenoids feature hard anodized components to ensure proper performance and long service life.
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 few specific applications that are known to have high failure rates for VVT solenoids include the GM 2.4L and Toyota 3.0L and 3.3L. As you can see below, Standard and Intermotor have these applications covered.
