Review on 🧰 ACDelco GM OE 12615873 VVT Solenoid for Variable Valve Timing by Mike Devine

Check Engine Light On, Scanner Coded Variable Valve Timing Solenoid On A 2005 Trailblazer. Flushed engine, put new oil in and put this solenoid valve in, reset engine light and everything works fine. Can't compete with the price of this genuine GM part. In the auto parts trade it costs almost twice as much. Note: (Oil deposits (deposits) clog the grooves in these solenoids and are the leading cause of failures. Flushing the engine and changing the oil will help keep the new one working properly.
