Review on APDTY 028320 Variable Valve Timing 🧰 Solenoid Replacement Options: 12636175, 12615613, 12586722, 12588943 by Jerry Anderson

These solenoids are awful! So after struggling for about an hour to get them through the new fillings, I decided to take one of the original Delco seals and put it in with no problem. The problem is these aftermarkets have a hard surface with no radius and if you measure the diameter you'll find that it's larger than the Delco so they can't go through the gasket. This makes it impossible to install them.
