CVVT Solenoid Cleaning with ReleaseTech Power Cleaner

How to clean a CVVT Solenoid.

One of our customers was experiencing frequent check engine lights (CEL) due to a clogged CVVT Solenoid.

The vehicle was a Tucson JM 2.0i with over 140k miles.  A history of low quality oil (dealer supplied) had taken its toll and the CVVT Solenoid would malfunction creating engine running problems and engine warning lights.

The customer added Oilsyn’s Ester-based Power Cleaner to the the engine oil and the problem disappeared within 500 miles of normal driving.  No more engine running difficulties or CELs.
