Review on 🌑️ ACDelco 213-77 Engine Coolant Temperature Sensor: Genuine GM Original Equipment for Optimal Performance by Justin Woolley

Revainrating 5 out of 5

Genuine AC Delco part (not a counterfeit)

This new OEM AC Delco Temperature Sensor (P/N 213-77) arrived on time and in AC Delco packaging. Please note that on LT1 engines this is NOT the temperature sensor on the water pump, it is the sensor on the passenger side of the engine which sends a signal to the dashboard mounted temperature sensor.

Pros
  • Durable Test Results
Cons
  • Long Lead Time
