Review on 🔍 APDTY 133830 Oil Pressure Sensor and Harness: Reliable Solution for Monitoring Oil Pressure by Michael Boyce

Good set and cheaper price than local stores. Will fit a 2003 Silverado 5.3 Vortec, good luck getting it between the cab and the rear of the engine. Pry out the old one with a rotary socket wrench, being careful not to drop old leaves or branches into the new hole. A rowdy like me can do it, and I'm just as stupid as they are, so I'm sure you won't have a problem. My symptoms too: random stepper motor clicking sound on the gauge and fluctuations from full oil pressure. until there is no more oil pressure. After I put the gauge in, he said I had good normal pressure.
