Review on 🧰 ACDelco GM OE 12615873 VVT Solenoid for Variable Valve Timing by Evan Beougher

I replaced it on my 2006 4.2L Trailblazer in less than 20 minutes. Most of the time I was looking for one of the power steering pump bolts which I kept dropping. Exact replacement. I'll let you know if I see an increase in fuel consumption per gallon. EDIT: I replaced it along with the fuel pump, camshaft position sensor and crankshaft position sensor and now the truck runs very smooth.
